2024-05-09 06:00:11 | Ummasking Tycoon 2FA: Un kit de phishing furtif utilisé pour contourner Microsoft 365 et Google MFA Unmasking Tycoon 2FA: A Stealthy Phishing Kit Used to Bypass Microsoft 365 and Google MFA (lien direct) |
Tycoon 2FA is a phishing-as-a-service (PhaaS) platform that was first seen in August 2023. Like many phish kits, it bypasses multifactor authentication (MFA) protections and poses a significant threat to users. Lately, Tycoon 2FA has been grabbing headlines because of its role in ongoing campaigns designed to target Microsoft 365 and Gmail accounts. This blog post is a rundown of how these attacks work, how they\'re evolving, what they look like in the real world-and how Proofpoint can help. How it works Tycoon 2FA operates as an adversary-in-the-middle (AitM) phishing kit. Its primary function is to harvest Microsoft 365 and Gmail session cookies. Attackers use these cookies to circumvent MFA access controls during subsequent authentication. That allows them to gain unauthorized access to a user\'s accounts, systems and cloud services-even those that have additional security measures in place. What\'s new In March 2024, the group behind Tycoon 2FA released an updated version of the kit. This new version boasts enhanced detection evasion capabilities that make it even harder for security systems to identify and block the kit. Significant alterations to the kit\'s JavaScript and HTML code have been implemented to increase its stealthiness and effectiveness. These changes include: Obfuscation techniques that scramble the code, making it difficult to understand Dynamic code generation that alters the code each time it runs, thereby enabling it to evade signature-based detection systems Where to find it The group behind Tycoon 2FA sells ready-to-use phishing pages for Microsoft 365 and Gmail via Telegram, a malicious cloud-based encrypted messaging service. Prices start at $120 for 10 days of access to the service, with variations based on top-level domains (TLDs). This business model broadens the potential pool of attackers because it allows less technically skilled bad actors to launch sophisticated phishing attacks. What an attack looks like Tycoon 2FA relies on attacker-controlled infrastructure to host the phishing webpage. Through the use of a “reverse proxy,” the platform allows the interception of victims\' entered credentials. The credentials are then relayed to the legitimate service for a transparent, successful login, prompting MFA requests. The resulting session cookies are relayed back to the threat actors. The stolen session credentials allow the attackers to bypass a company\'s MFA protection if they remain active. This gives them unauthorized access to the user\'s account. Real-world examples Since December 2023, Proofpoint has observed phishing landing pages that use Tycoon 2FA to facilitate MFA token theft and bypass.

2024-05-08 06:00:27 | Comment les attaquants utilisent-ils des e-mails usurpés pour détourner vos communications commerciales?4 scénarios de risque How Do Attackers Use Spoofed Email to Hijack Your Business Communications? 4 Risk Scenarios (lien direct) |
When you hear the term “spoofed” email, does business email compromise (BEC) come to mind? It does for many people-especially security leaders. BEC is a form of email fraud, and it has been a top concern for chief information security officers for years. BEC scams are a costly problem. The latest Internet Crime Report from the FBI\'s Internet Crime Complaint Center (IC3) notes that adjusted losses from BEC were $2.9 billion last year. Since 2013, accumulated financial losses due to BEC have reached nearly $53 billion. Spoofing is impersonation, and it is the essence of email fraud. It is also one of the most common techniques used in other types of attacks like phishing and ransomware. Your business, like many, probably focuses on stopping spoofed emails before they can reach employees\' inboxes. However, there is more to worry about. Spoofed email has the potential to damage your brand reputation and jeopardize your business ecosystem, too. In this post, we will explore various impersonation risk scenarios. But first, let\'s look at some common tactics. Impersonation tactics Here are some common methods bad actors use to impersonate others so they can further their attacks. Display name spoofing. The display name appears in the “From:” field of an email. It is the easiest email identifier to manipulate. Attackers forge email headers so that client software displays the fraudulent sender, which most users take at face value. Domain spoofing. Bad actors will use an exact match of an organization\'s domain to launch this type of fraud attack. Attackers who engage in domain spoofing will attempt to imitate the sending server or sending domain. Lookalike domains. Third parties can register lookalike domains and send email that appears to have come from a trusted source. Compromised supplier accounts. In some advanced attacks, attackers will compromise an account from a supplier that works with the business that they want to target. They will use the compromised supplier account to hijack the email communication between their target and its supplier. Eventually, attackers are in a position to launch an attack or solicit fraudulent payment or sensitive data. Attack scenarios Now, let\'s dive into how attackers can use spoofed emails to exploit the trusted relationships you have with your customers, business partners, suppliers and employees. Scenario 1: Impersonate you to target your employees You are probably most familiar with the first scenario, where attackers pretend to be someone within your company, like your CEO or manager. The scam often starts with a simple lure that seems to be a benign message like: How is your day? Are you at your desk? Can you help me with something urgent? Once attackers get a victim to engage, the conversation evolves. The bad actor may request the victim to purchase gift cards for them, proceed with a fraudulent payment, or share confidential data. Not only can attackers impersonate executives, but they can also pretend to be general employees asking human resources to redirect their payrolls. In short, it doesn\'t matter what a victim\'s role is. Anyone can be impersonated to target anyone within an organization. An example of a simple lure where the attacker used display name spoofing to impersonate Ken, the CEO. Another example of a BEC lure where an attacker used a lookalike domain of Watertronics (vs. waltertronics, in the example) to spoof their CEO. Scenario 2: Exploit your suppliers or business partners to target your employees The most common theme in this scenario is supplier invoicing fraud. Bad actors will exploit a company\'s suppliers using tactics such as malicious lookalike domains of suppliers or compromised supplier accounts to either send a fake invoice or request the victim to redirect the payment to a bank account that the attackers control.

Chief information security officers (CISOs) face a daunting challenge as they work to integrate generative AI (GenAI) tools into business workflows. Robust data protection measures are important to protect sensitive data from being leaked through GenAI tools. But CISOs can\'t just block access to GenAI tools entirely. They must find ways to give users access because these tools increase productivity and drive innovation. Unfortunately, legacy data loss prevention (DLP) tools can\'t help with achieving the delicate balance between security and usability. Today\'s release of Proofpoint DLP Transform changes all that. It provides a modern alternative to legacy DLP tools in a single, economically attractive package. Its innovative features help CISOs strike the right balance between protecting data and usability. It\'s the latest addition to our award-winning DLP solution, which was recognized as a 2024 Gartner® Peer Insights™ Customers\' Choice for Data Loss Prevention. Proofpoint was the only vendor that placed in the upper right “Customers\' Choice” Quadrant. In this blog, we\'ll dig into some of our latest research about GenAI and data loss risks. And we\'ll explain how Proofpoint DLP Transform provides you with a human-centric approach to reduce those risks. GenAI increases data loss risks Users can make great leaps in productivity with ChatGPT and other GenAI tools. However, GenAI also introduces a new channel for data loss. Employees often enter confidential data into these tools as they use them to expedite their tasks. Security pros are worried, too. Recent Proofpoint research shows that: Generative AI is the fastest-growing area of concern for CISOs 59% of board members believe that GenAI is a security risk for their business “Browsing GenAI sites” is one of the top five alert scenarios configured by companies that use Proofpoint Information Protection Valuable business data like mergers and acquisitions (M&A) documents, supplier contracts, and price lists are listed as the top data to protect A big problem faced by CISOs is that legacy DLP tools can\'t capture user behavior and respond to natural language processing-based user interfaces. This leaves security gaps. That\'s why they often use blunt tools like web filtering to block employees from using GenAI apps altogether. You can\'t enforce acceptable use policies for GenAI if you don\'t understand your content and how employees are interacting with it. If you want your employees to use these tools without putting your data security at risk, you need to take a human-centric approach to data loss. A human-centric approach stops data loss With a human-centric approach, you can detect data loss risk across endpoints and cloud apps like Microsoft 365, Google Workspace and Salesforce with speed. Insights into user intent allow you to move fast and take the right steps to respond to data risk. Proofpoint DLP Transform takes a human-centric approach to solving the security gaps with GenAI. It understands employee behavior as well as the data that they are handling. It surgically allows and disallows employees to use GenAI tools such as OpenAI ChatGPT and Google Gemini based on employee behavior and content inputs, even if the data has been manipulated or has gone through multiple channels (email, web, endpoint or cloud) before reaching it. Proofpoint DLP Transform accurately identifies sensitive content using classical content and LLM-powered data classifiers and provides deep visibility into user behavior. This added context enables analysts to reach high-fidelity verdicts about data risk across all key channels including email, cloud, and managed and unmanaged endpoints. With a unified console and powerful analytics, Proofpoint DLP Transform can accelerate incident resolution natively or as part of the security operations (SOC) ecosystem. It is built on a cloud-native architecture and features modern privacy controls. Its lightweight and highly stable user-mode agent is unique in | Tool Medical Cloud | ChatGPT | ★★★ |

Engineering Insights is an ongoing blog series that gives a behind-the-scenes look into the technical challenges, lessons and advances that help our customers protect people and defend data every day. Each post is a firsthand account by one of our engineers about the process that led up to a Proofpoint innovation. In the nascent world of large language models (LLMs), prompt engineering has emerged as a critical discipline. However, as LLM applications expand, it is becoming a more complex challenge to manage and maintain a library of related prompts. At Proofpoint, we developed Exploding Prompts to manage the complexity through exploding template composition. We first created the prompts to generate soft labels for our data across a multitude of models and labeling concerns. But Exploding Prompts has also enabled use cases for LLMs that were previously locked away because managing the prompt lifecycle is so complex. Recently, we\'ve seen exciting progress in the field of automated prompt generation and black-box prompt optimization through DSPy. Black-box optimization requires hand-labeled data to generate prompts automatically-a luxury that\'s not always an option. You can use Exploding Prompts to generate labels for unlabeled data, as well as for any prompt-tuning application without a clear (or tractable) objective for optimization. In the future, Exploding Prompts could be used with DSPy to achieve a human-in-the-loop feedback cycle. We are also thrilled to announce that Exploding Prompts is now an open-source release. We encourage you to explore the code and consider how you might help make it even better. The challenge: managing complexity in prompt engineering Prompt engineering is not just about crafting queries that guide intelligent systems to generate the desired outputs; it\'s about doing it at scale. As developers push the boundaries of what is possible with LLMs, the need to manage a vast array of prompts efficiently becomes more pressing. Traditional methods often need manual adjustments and updates across numerous templates, which is a process that\'s both time-consuming and error-prone. To understand this problem, just consider the following scenario. You need to label a large quantity of data. You have multiple labels that can apply to each piece of data. And each label requires its own prompt template. You timebox your work and find a prompt template that achieves desirable results for your first label. Happily, most of the template is reusable. So, for the next label, you copy-paste the template and change the portion of the prompt that is specific to the label itself. You continue doing this until you figure out the section of the template that has persisted through each version of your labels can be improved. Now you now face the task of iterating through potentially dozens of templates to make a minor update to each of the files. Once you finish, your artificial intelligence (AI) provider releases a new model that outperforms your current model. But there\'s a catch. The new model requires another small update to each of your templates. To your chagrin, the task of managing the lifecycle of your templates soon takes up most of your time. The solution: exploding prompts from automated dependency graphs Prompt templating is a popular way to manage complexity. Exploding Prompts builds on prompt templating by introducing an “explode” operation. This allows a few single-purpose templates to explode into a multitude of prompts. This is accomplished by building dependency graphs automatically from the directory structure and the content of prompt template files. At its core, Exploding Prompts embodies the “write it once” philosophy. It ensures that every change made in a template correlates with a single update in one file. This enhances efficiency and consistency, as updates automatically propagate across all relevant generated prompts. This separation ensures that updates can be made with speed and efficiency so you can focus on innovation rather th | Malware Tool Threat Studies Cloud Technical | ★★★ | |

This blog post is part of a monthly series, Cybersecurity Stop of the Month, which explores the ever-evolving tactics of today\'s cybercriminals. It focuses on the critical first three steps in the attack chain in the context of email threats. The goal of this series is to help you understand how to fortify your defenses to protect people and defend data against emerging threats in today\'s dynamic threat landscape. The critical first three steps of the attack chain-reconnaissance, initial compromise and persistence. So far in this series, we have examined these types of attacks: Supplier compromise EvilProxy SocGholish eSignature phishing QR code phishing Telephone-oriented attack delivery (TOAD) Payroll diversion MFA manipulation Supply chain compromise Multilayered malicious QR code attack In this post, we examine an emerging threat-the use of malicious cloud applications created within compromised cloud tenants following account takeover. We refer to it as MACT, for short. Background Cloud account takeover (ATO) attacks are a well-known risk. Research by Proofpoint found that last year more than 96% of businesses were actively targeted by these attacks and about 60% had at least one incident. Financial damages reached an all-time high. These findings are unsettling. But there is more for businesses to worry about. Cybercriminals and state-sponsored entities are rapidly adopting advanced post-ATO techniques. And they have embraced the use of malicious and abused OAuth apps. In January 2024, Microsoft revealed that a nation-state attacker had compromised its cloud environments and stolen valuable data. This attack was attributed to TA421 (aka Midnight Blizzard and APT29), which are threat groups that have been attributed to Russia\'s Foreign Intelligence Service (SVR). Attackers exploited existing OAuth apps and created new ones within hijacked cloud tenants. After the incident, CISA issued a new advisory for businesses that rely on cloud infrastructures. Proofpoint threat researchers observed attackers pivoting to the use of OAuth apps from compromised-and often verified-cloud tenants. Threat actors take advantage of the trust that\'s associated with verified or recognized identities to spread cloud malware threats as well as establish persistent access to sensitive resources. The scenario Proofpoint monitors a malicious campaign named MACT Campaign 1445. It combines a known tactic used by cloud ATO attackers with new tactics, techniques and procedures. So far, it has affected dozens of businesses and users. In this campaign, attackers use hijacked user accounts to create malicious internal apps. In tandem, they also conduct reconnaissance, exfiltrate data and launch additional attacks. Attackers use a unique anomalous URL for the malicious OAuth apps\' reply URL-a local loopback with port 7823. This port is used for TCP traffic. It is also associated with a known Windows Remote Access Trojan (RAT). Recently, Proofpoint researchers found four accounts at a large company in the hospitality industry compromised by attackers. In a matter of days, attackers used these accounts to create four distinct malicious OAuth apps. The threat: How did the attack happen? Here is a closer look at how the attack unfolded. Initial access vectors. Attackers used a reverse proxy toolkit to target cloud user accounts. They sent individualized phishing lures to these users, which enabled them to steal their credentials as well as multifactor authentication (MFA) tokens. A shared PDF file with an embedded phishing URL that attackers used to steal users\' credentials. Unauthorized access (cloud account takeover). Once attackers had stolen users\' credentials, they established unauthorized access to the four targeted accounts.

For years, the Proofpoint Cloud Research team has been particularly focused on the constantly changing landscape of cloud malware threats. While precise future predictions remain elusive, a retrospective examination of 2023 enabled us to discern significant shifts and trends in threat actors\' behaviors, thereby informing our projections for the developments expected in 2024. There is no doubt that one of the major, and most concerning, trends observed in 2023 was the increased adoption of malicious and abused OAuth applications by cybercriminals and state-sponsored actors. In January, Microsoft announced they, among other organizations, were targeted by a sophisticated nation-state attack. It seems that the significant impact of this attack, which was attributed to TA421 (AKA Midnight Blizzard and APT29), largely stemmed from the strategic exploitation of pre-existing OAuth applications, coupled with the creation of new malicious applications within compromised environments. Adding to a long list of data breaches, this incident emphasizes the inherent potential risk that users and organizations face when using inadequately protected cloud environments. Expanding on early insights shared in our 2021 blog, where we first explored the emerging phenomenon of application creation attacks and armed with extensive recent discoveries, we delve into the latest developments concerning this threat in our 2024 update. In this blog, we will: Define key fundamental terms pertinent to the realm of cloud malware and OAuth threats. Examine some of the current tactics, techniques, and procedures (TTPs) employed by threat actors as part of their account-takeover (ATO) kill chain. Provide specific IOCs related to recently detected threats and campaigns. Highlight effective strategies and solutions to help protect organizations and users against cloud malware threats. Basic terminology OAuth (Open Authorization) 2.0. OAuth is an open standard protocol that enables third-party applications to access a user\'s data without exposing credentials. It is widely used to facilitate secure authentication and authorization processes. Line-of-business (LOB) applications. LOB apps (also known as second-party apps) typically refer to applications created by a user within their cloud environment in order to support a specific purpose for the organization. Cloud malware. A term usually referring to malicious applications created, utilized and proliferated by threat actors. Malicious apps can be leveraged for various purposes, such as: mailbox access, file access, data exfiltration, internal reconnaissance, and maintaining persistent access to specific resources. MACT (Malicious Applications Created in Compromised Credible Tenants). A common technique wherein threat actors create new applications within hijacked environments, exploiting unauthorized access to compromised accounts to initiate additional attacks and establish a persistent foothold within impacted cloud tenants. Apphish. A term denoting the fusion of cloud apps-based malware with phishing tactics, mainly by utilizing OAuth 2.0 infrastructure to implement open redirection attacks. Targeted users could be taken to a designated phishing webpage upon clicking an app\'s consent link. Alternatively, redirection to a malicious webpage could follow authorizing or declining an application\'s consent request. Abused OAuth applications. Benign apps that are authorized or used by attackers, usually following a successful account takeover, to perform illegitimate activities. What we are seeing Already in 2020, we witnessed a rise in malicious OAuth applications targeting cloud users, with bad actors utilizing increasingly sophisticated methods such as application impersonation and diverse lures. In October 2022, Proofpoint researchers demonstrated how different threat actors capitalized on the global relevance of the COVID-19 pandemic to spread malware and phishing threats.

In this two-part blog series, we will address many of the frequently asked questions submitted by attendees. In our first installment, we address questions related to the threat landscape. Understanding the threat landscape is paramount in crafting a human-centric security strategy. That\'s the goal behind our 10th annual State of the Phish report. When you know what threats are out there and how people are interacting with them, you can create a modern cybersecurity strategy that puts the complexity of human behavior and interaction at the forefront. Our report was launched a month ago. Since then, we\'ve followed up with a few webinars to discuss key findings from the report, including: Threat landscape findings: Over 1 million phishing threats involved EvilProxy, which bypasses multifactor authentication (MFA). Yet, 89% of security pros still believe that MFA provides complete protection against account takeover. BEC threat actors benefit from generative AI. Proofpoint detected and stopped over 66 million targeted business email compromise (BEC) attacks per month on average in 2023. User behavior and attitude findings: 71% of surveyed users took at least one risky action, and 96% of them knew that those actions were associated with risk. 58% of those risky actions were related to social engineering tactics. 85% of security pros believed that most employees know they are responsible for security. Yet nearly 60% of employees either weren\'t sure or disagreed. These findings inspired hundreds of questions from audiences across the world. What follows are some of the questions that repeatedly came up. Frequently asked questions What are the definitions of BEC and TOAD? Business email compromise (BEC) essentially means fraud perpetrated through email. It can take many forms, such as advance fee fraud, payroll redirection, fraudulent invoicing or even extortion. BEC typically involves a deception, such as the spoofing of a trusted third party\'s domain or the impersonation of an executive (or literally anyone the recipient trusts). BEC is hard to detect because it is generally pure social engineering. In other words, there is often no credential harvesting portal or malicious payload involved. Threat actors most often use benign conversation to engage the victim. Once the victim is hooked, attackers then convince that person to act in favor of them, such as wiring money to a specified account. Similarly, telephone-oriented attack delivery (TOAD) attacks also use benign conversations. But, in this case, a threat actor\'s goal is to motivate the victim to make a phone call. From there, they will walk their target through a set of steps, which usually involve tricking the victim into giving up their credentials or installing a piece of malware on their computer. TOAD attacks have been associated with high-profile malware families known to lead to ransomware, as well as with a wide variety of remote access tools like AnyDesk that provide the threat actors direct access to victims\' machines. The end goal might still be fraud; for example, there have been cases where payment was solicited for “IT services” or software (Norton LifeLock). But the key differentiator for TOAD, compared with BEC, is the pivot out of the email space to a phone call., is the pivot out of the email space to the phone. What is the difference between TOAD and vishing? TOAD often starts with an email and requires victims to call the fraudulent number within that email. Vishing, on the other hand, generally refers to fraudulent solicitation of personally identifiable information (PII) and may or may not involve email (it could result from a direct call). Some TOAD attempts may fall into this category, but most perpetrators focus on getting software installed on a victim\'s machine. How do you see artificial intelligence (AI) affecting phishing?

2024-03-25 06:00:56 | DNS pendante: nettoyage de printemps pour protéger contre le risque d'identification Dangling DNS: Spring Cleaning to Protect Against Impersonation Risk (lien direct) |
It is well-established that email is the number one threat vector for cyberattacks. It\'s a go-to for many bad actors because they don\'t need to be highly skilled to initiate an email-based attack. Nor do they need to do elaborate work upfront. Their success hinges on their ability to be convincing. Targets must believe that they are interacting with a trusted source if they\'re going to voluntarily hand over sensitive data, provide their authentication credentials, make a wire transfer or install malware. That\'s why a critical part of any company\'s security posture is using protocols and policies that reduce impersonation risk. And a major step in this direction is to enable and enforce email authentication methods across all your domains. These include: Sender Policy Framework (SPF). This is a published authoritative list of approved sending IP addresses. It can help recipient email systems confirm that an email is coming from a legitimate source and is not impersonating a person or entity through spoofing. DomainKeys Identified Mail (DKIM). This email authentication method stamps a digital signature to outgoing emails. It helps recipient email systems verify, with proper alignment, that the email was sent by the domain it claims to be from and that it hasn\'t been altered in transit. Domain-based Message Authentication, Reporting, and Conformance (DMARC). This email authentication protocol builds on SPF and DKIM by allowing senders to set policies for handling emails that fail these authentication checks. If you don\'t maintain your systems, bad actors can exploit out-of-date information and nullify your email authentication efforts. In this blog, we will highlight a key bad actor impersonation tactic to inspire you to regularly spring clean your records moving forward. The tactic in focus: “dangling DNS” Dangling DNS refers to a misconfiguration in your email-related domain name system (DNS) records. A reference domain or subdomain is left pointing to a domain that no longer exists or is not under the control of the original domain owner. The term “dangling" implies that the DNS entry is pointing to something that is hanging without proper support. In this case, it is a domain that has expired. Bad actors have gotten wise to the fact that these expired domains create a crack in your defense that they can exploit. The risk of subdomain takeover If a subdomain is left pointing to an external service that the domain owner no longer controls, an attacker can register that domain to gain control of any DNS records that are pointed toward it. So, when they initiate their impersonation-based attack, they have the added benefit of passing email authentication! Using SPF records with all your sending infrastructure listed, rather than hidden behind an SPF macro, also discloses sensitive data about your company\'s infrastructure. Attackers can use this data to plan and execute targeted attacks. Actions you can take to reduce risk To mitigate the risks associated with dangling DNS records, domain owners must review their email-related DNS configurations regularly. It is especially important when you decommission or change services. Here are some actions that can help you to reduce your risk exposure. Regularly review and remove unused DNS records You should promptly remove DNS records that point to deprecated or unused services: SPF records. Review and minimize the entries that are posted within your SPF record. Review every “Include” and “Reference”, especially for third parties and expired domains, or if domains change owners. Access to SPF telemetry data can help simplify your investigations. DKIM selector records. Review CNAMEd DKIM selector records that point to third parties for expired domains, or if domains change owners. DMARC policy records. Review CNAMEd DMARC records that point to third parties for expired domains, or if domains change owners. MX records.

This cybersecurity lore is well on its way to becoming cliché. But like most clichés, it\'s true: Data doesn\'t leave your organization on its own. People let your data out. They either take it with them, or they leave the door open for someone else to help themselves. In this environment, where cybercriminals are less inclined to target software vulnerabilities and far more focused on our identities, the perimeter as we once knew it has disappeared. Today, our people are the perimeter-wherever they are, on-premises or in the cloud, and whatever systems, devices and credentials they use to access our data. Needless to say, if cyberattacks are targeted at our people (or rather, their identities), then our cyber defenses must be targeted, too. But with large and often remote workforces accessing our networks across various endpoints, this is increasingly challenging. To protect our people-and, in turn, our businesses-we need a deep understanding of who is accessing our data as well as how, when, where and why. It\'s only when we have all this information that we can begin to place protections where they are needed most, educate users on the risks they face and fight threat actors on the new frontier of our identities. Tackling insider threats As if defending a new, more fluid perimeter wasn\'t difficult enough, the increased focus on our identities presents another problem. Our people are already within our traditional defenses. So, to protect against malicious, compromised or careless users who are enabling data loss, we need to defend from the inside out. Email remains the number one entry point for common and advanced threats, so any effective defense starts in the inbox. Our people must understand the importance of strong credentials, the risk of password reuse and sharing, and the dangers posed by phishing emails, malicious links and bogus attachments. In our research for the 2024 State of the Phish report, Proofpoint found that security professionals in Europe and the Middle East rated password reuse as the riskiest behavior-and the second-most common behavior among end users. Email protection tools can assist here, too, by filtering malicious messages before they reach the inbox. That helps to mitigate the compromised employee use case. However, security teams must always assume that threats will get through these lines of defense, even with detection rates above 99% being the norm. And when they do, additional layers of security are needed to stop them in their tracks. Advanced enterprise data loss prevention (DLP) and insider threat management (ITM) tools provide this additional layer. By analyzing content, behavior and threat telemetry, these tools highlight anomalous or suspicious behavior that can lead to data loss. Careless users were the most cited cause of data loss in our inaugural 2024 Data Loss Landscape report. To handle this use case you might want to interrupt their careless behavior with a security prompt. For example, suppose an employee attempts to send confidential files in a plain text email. A simple pop-up advising them to reconsider their action could prevent this data from being exposed. A complete log of the incident is also captured, which can add real-world context to security awareness training. Another action that a careless user may perform is to send an email to the wrong recipient. According to our research, 1 in 3 users misdirected one or two emails to the wrong recipient. In the event of a malicious insider, intelligent DLP and ITM tools will spot and alert security teams to any high-risk behaviors. This could be a user who downloads an unauthorized app to a corporate machine or renames files to hide their intentions and cover their tracks. As for leavers-who remain one of the primary reasons for insider-driven data loss-security teams can take a more proactive approach. By focusing on these high-risk employees, you can build an evidential picture of intent. With the right tools in place, you can capture activity l | Tool Vulnerability Threat Cloud | ★★ | |

La perte de données est un problème de personnes, ou plus précisément, un problème de personnes imprudentes.C'est la conclusion de notre nouveau rapport, le paysage de la perte de données 2024, que Proofpoint lance aujourd'hui. Nous avons utilisé des réponses à l'enquête de 600 professionnels de la sécurité et des données de la protection des informations de Proofpoint pour explorer l'état actuel de la prévention de la perte de données (DLP) et des menaces d'initiés.Dans notre rapport, nous considérons également ce qui est susceptible de venir ensuite dans cet espace à maturation rapide. De nombreuses entreprises considèrent aujourd'hui toujours leur programme DLP actuel comme émergent ou évoluant.Nous voulions donc identifier les défis actuels et découvrir des domaines d'opportunité d'amélioration.Les praticiens de 12 pays et 17 industries ont répondu aux questions allant du comportement des utilisateurs aux conséquences réglementaires et partageaient leurs aspirations à l'état futur de DLP \\. Ce rapport est une première pour Proofpoint.Nous espérons que cela deviendra une lecture essentielle pour toute personne impliquée dans la tenue de sécuriser les données.Voici quelques thèmes clés du rapport du paysage de la perte de données 2024. La perte de données est un problème de personnes Les outils comptent, mais la perte de données est définitivement un problème de personnes.2023 Données de Tessian, une entreprise de point de preuve, montre que 33% des utilisateurs envoient une moyenne d'un peu moins de deux e-mails mal dirigés chaque année.Et les données de la protection de l'information ProofPoint suggèrent que à peu de 1% des utilisateurs sont responsables de 90% des alertes DLP dans de nombreuses entreprises. La perte de données est souvent causée par la négligence Les initiés malveillants et les attaquants externes constituent une menace significative pour les données.Cependant, plus de 70% des répondants ont déclaré que les utilisateurs imprudents étaient une cause de perte de données pour leur entreprise.En revanche, moins de 50% ont cité des systèmes compromis ou mal configurés. La perte de données est répandue La grande majorité des répondants de notre enquête ont signalé au moins un incident de perte de données.Les incidents moyens globaux par organisation sont de 15. L'échelle de ce problème est intimidante, car un travail hybride, l'adoption du cloud et des taux élevés de roulement des employés créent tous un risque élevé de données perdues. La perte de données est dommageable Plus de la moitié des répondants ont déclaré que les incidents de perte de données entraînaient des perturbations commerciales et une perte de revenus.Celles-ci ne sont pas les seules conséquences dommageables.Près de 40% ont également déclaré que leur réputation avait été endommagée, tandis que plus d'un tiers a déclaré que leur position concurrentielle avait été affaiblie.De plus, 36% des répondants ont déclaré avoir été touchés par des pénalités réglementaires ou des amendes. Préoccupation croissante concernant l'IA génératrice De nouvelles alertes déclenchées par l'utilisation d'outils comme Chatgpt, Grammarly et Google Bard ne sont devenus disponibles que dans la protection des informations de Proofpoint cette année.Mais ils figurent déjà dans les cinq règles les plus implémentées parmi nos utilisateurs.Avec peu de transparence sur la façon dont les données soumises aux systèmes d'IA génératives sont stockées et utilisées, ces outils représentent un nouveau canal dangereux pour la perte de données.

2024-03-14 06:00:19 | Comment nous avons déployé Github Copilot pour augmenter la productivité des développeurs How We Rolled Out GitHub Copilot to Increase Developer Productivity (lien direct) |
Engineering Insights is an ongoing blog series that gives a behind-the-scenes look into the technical challenges, lessons and advances that help our customers protect people and defend data every day. Each post is a firsthand account by one of our engineers about the process that led up to a Proofpoint innovation. Inspired by the rapid rise of generative artificial intelligence (GenAI), we recently kicked off several internal initiatives at Proofpoint that focused on using it within our products. One of our leadership team\'s goals was to find a tool to help increase developer productivity and satisfaction. The timing was perfect to explore options, as the market had become flush with AI-assisted coding tools. Our project was to analyze the available tools on the market in-depth. We wanted to choose an AI assistant that would provide the best productivity results while also conforming to data governance policies. We set an aggressive timeline to analyze the tools, collaborate with key stakeholders from legal, procurement, finance and the business side, and then deploy the tool across our teams. In the end, we selected GitHub Copilot, a code completion tool developed by GitHub and OpenAI, as our AI coding assistant. In this post, we walk through how we arrived at this decision. We also share the qualitative and quantitative results that we\'ve seen since we\'ve introduced it. Our analysis: approach and criteria When you want to buy a race car-or any car for that matter-it is unlikely that you\'ll look at just one car before making a final decision. As engineers, we are wired to conduct analyses that dive deeply into all the possible best options as well as list all the pros and cons of each. And that\'s what we did here, which led us to a final four list that included GitHub Copilot. These are the criteria that we considered: Languages supported IDEs supported Code ownership Stability AI models used Protection for intellectual property (IP) Licensing terms Security Service-level agreements Chat interface Innovation Special powers Pricing Data governance Support for a broad set of code repositories We took each of the four products on our shortlist for a test drive using a specific set of standard use cases. These use cases were solicited from several engineering teams. They covered a wide range of tasks that we anticipated would be exercised with an AI assistant. For example, we needed the tool to assist not just developers, but also document writers and automation engineers. We had multiple conversations and in-depth demos from the vendors. And when possible, we did customer reference checks as well. Execution: a global rollout Once we selected a vendor, we rolled out the tool to all Proofpoint developers across the globe. We use different code repos, programming languages and IDEs-so, we\'re talking about a lot of permutations and combinations. Our initial rollout covered approximately 50% of our team from various business units and roles for about 30 days. We offered training sessions internally to share best practices and address challenges. We also built an internal community of experts to answer questions. Many issues that came up were ironed out during this pilot phase so that when we went live, it was a smooth process. We only had a few issues. All stakeholders were aware of the progress, from our operations/IT team to our procurement and finance teams. Our journey from start to finish was about 100 days. This might seem like a long time, but we wanted to be sure of our choice. After all, it is difficult to hit “rewind” on an important initiative of this magnitude. Monitoring and measuring results We have been using GitHub Copilot for more than 150 days and during that period we\'ve been collecting telemetry data from the tool and correlating it with several productivity and quality metrics. Our results have been impressive. When it comes to quantitative results, we have seen a general increase in | Tool Cloud Technical | ★★★ | |

By now, much of the industry has seen the big news about Cohesity acquiring the enterprise data protection business of Veritas Technologies. The transaction will see the company\'s NetBackup technology-software, appliances and cloud (Alta Data Protection)-integrated into the Cohesity ecosystem. But what about other Veritas products? As stated in the Cohesity and Veritas press releases, the “remaining assets of Veritas\' businesses will form a separate company, \'DataCo.\' \'DataCo\' will comprise Veritas\' InfoScale, Data Compliance, and Backup Exec businesses.” Data Compliance includes Veritas Enterprise Vault (EV), which might raise concerns for EV customers. As a new, standalone entity, \'DataCo\' has no innovation track record. In this blog, I provide my opinion on the questionable future of Veritas archiving products, why EV customers should start looking at alternative archiving tools, and why you should trust Proofpoint as your next enterprise archiving solution. EV architecture isn\'t future-proof EV gained a following because it came onto the market just when it was needed. With its big, robust on-premises architecture, EV was ideal to solve the challenges of bloated file and email servers. Companies had on-premises file and email servers that were getting bogged down with too much data. They needed a tool to offload legacy data to keep working and so they could be backed up in a reasonable amount of time. However, with key applications having moved to the cloud over the last decade-plus, storage optimization is no longer a primary use case for archiving customers. While EV has adapted to e-discovery and compliance use cases, its underlying on-premises architecture has struggled to keep up. EV customers still have headaches with infrastructure (hardware and software) planning, budgeting and maintenance, and archive administration. What\'s more, upgrades often require assistance from professional services and support costs are rising. And the list goes on. Today, most cloud-native archives remove virtually all of these headaches. And just like you moved on from DVDs and Blu-ray discs to streaming video, it\'s time to migrate from legacy on-premises archiving architectures, like EV, to cloud-native solutions. Future investments are uncertain When you look back over EV\'s last 5-6 years, you might question what significant innovations Veritas has delivered for EV. Yes, Veritas finally released supervision in the cloud. But that was a direct response to the EOL of AdvisorMail for EV.cloud many years ago. Yes, Veritas added dozens of new data sources for EV. But that was achieved through the acquisition of Globanet-and their product Merge1-in 2020. (They still list Merge1 as an independent product on their website.) Yes, they highlight how EV can store to “Azure, AWS, Google Cloud Storage, and other public cloud repositories” via storage tiering. But that just means that EV extends the physical storage layer of a legacy on-prem archiving architecture to the cloud-it doesn\'t mean it runs a cloud-native archiving solution. Yes, Veritas has cloud-based Alta Archiving. But that\'s just a rebranding and repackaging of EV.cloud, which they retired more than two years ago. Plus, Alta Archiving and Enterprise Vault are separate products. With the Cohesity data protection acquisition, EV customers have a right to question future investments in their product. Will EV revenue alone be able to sustain meaningful, future innovation in the absence of the NetBackup revenue “cash cow”? Will you cling to hope, only to be issued an EOL notice like Dell EMC SourceOne customers? Now is the time to migrate from EV to a modern cloud-native archiving solution.

Protecting people and defending data are ongoing priorities for federal agencies whose missions are constantly under attack. These entities struggle to keep pace with an array of potent threats, like insiders who steal secrets about missile technology and threat actors who use living off the land techniques (LOTL). Proofpoint can provide agencies with a critical edge in their efforts to defend data from risky users and detect real-time identity threats. Products to help with these challenges include: Proofpoint Insider Threat Management Proofpoint Identity Threat Defense This blog takes a closer look at these products and how they help our federal customers. Understand the context behind user behavior with Proofpoint ITM Across all levels of government, data loss is costly-these incidents have cost agencies $26 billion over the past eight years. A critical first step toward preventing data loss and risky behavior is to understand that data does not lose itself. People lose it. Employees, third parties and contractors have access to more data than ever-on their laptops, in email and the cloud. But you can\'t reduce the risk of insider threats without first understanding the context behind user behavior. Context also helps you to choose the best response when an insider-led incident occurs, whether it\'s due to a malicious, compromised or careless user. Proofpoint ITM can help you gain that vital context. It also helps you to move swiftly to address insider threats. Here\'s how: Get a clear picture of threats. You can gain complete context into users and their data activity on endpoints, and web and cloud applications. User attribution is easy thanks to a clear, visual timeline and flexible, real-time screenshots. Identify risks proactively. Proofpoint includes preconfigured indicators of risk that can help you catch user activities in real time, like data exfiltration, privilege abuse, unauthorized access and security controls bypass. The out-of-the-box Insider Threat Library was built using feedback from our customers as well as guidelines from NIST, MITRE and the CERT Division of the Software Engineering Institute at Carnegie Mellon. Investigate faster. You can investigate incidents with more efficiency when you can see user intent. With Proofpoint ITM, you can gather, package and export the evidence (who, what, where, when and user intent) and share it easily with groups outside of security such as HR, legal and privacy. This saves time and reduces the cost of investigations. Get better time to value. Proofpoint ITM has a single, lightweight user-mode agent that is easy to install and invisible to your users. With a converged DLP and ITM solution, you can monitor everyday and risky users. Gain efficiencies and manage risks Here are more ways that Proofpoint ITM helps federal agencies: Manage alert rules efficiently. Alert rules are grouped by categories and assigned to user lists, which streamlines management. Comply with privacy laws. Agencies can protect privacy by anonymizing users in the dashboard, which helps eliminate bias in investigations. Manage risks at a department level. Large agencies can manage employee risks based on their department or group by using Active Directory group-based permissions. Each group has a dedicated security team member or manager. Meet zero trust and CMMC needs Agencies can use ITM to meet their zero trust and Cybersecurity Maturity Model Certification (CMMC) needs as well. Proofpoint ITM capabilities support several pillars of Zero Trust and more than seven domains of CMMC. For Zero Trust, Proofpoint ITM helps agencies align to these pillars: Department of Defense: Data and Visibility and Analytics Pillar Cybersecurity and Infrastructure Security Agency: Data and Devices Pillars Proofpoint Information Protection products help our customers with these CMMC domains: Access Controls Asset Management Audit and Accountability Configuration Management Incident Response Media Protect | Ransomware Vulnerability Threat Cloud | ★★★ | |

2024-02-29 06:00:13 | Briser la chaîne d'attaque: des mouvements décisifs Break the Attack Chain: Decisive Moves (lien direct) |
In our “Break the Attack Chain” blog series, we have looked at how threat actors compromise our defenses and move laterally within our networks to escalate privileges and prepare for their endgame. Now, we come to the final stage of the attack chain where it\'s necessary to broaden our outlook a little. While most external threat actors will follow the same playbook, they aren\'t our only adversaries. The modern reality is that data often just walks out of the door because our employees take it with them. More than 40% of employees admit to taking data when they leave. At the same time, careless employees who make security mistakes are responsible for more than half of insider-led data loss incidents. So, while it\'s important to detect and deter cybercriminals who want to exfiltrate our data, we must also watch out for our users. Whether they are malicious or careless, our users are just as capable of exposing sensitive data. In this third and final installment, we discuss how companies tend to lose data-and how we can better protect it from all manner of risks. Understanding data loss As with every stage in the attack chain, we must first understand threats before we can put protections in place. Let\'s start with the case of a cybercriminal following the typical attack chain. While this may not sound like a traditional insider attack, it\'s often aided by careless or reckless employees. Users expose data and open themselves and your business up to compromise in a multitude of ways, like using weak passwords, reusing credentials, forgoing security best practices and clicking on malicious links or attachments. Any of these risky moves give cybercriminals a way into your networks where they can embark on lateral movement and escalation. Incidents like these are so common that careless or compromised users cause over 80% of insider-led data loss. Malicious insiders make up the remainder. Insider threats could be a disgruntled employee looking to cause disruption, a user compromised by cybercriminals, or, increasingly, an employee who will soon leave your organization. In most cases, data exfiltration follows a three-stage pattern: Access. Users, whether malicious or compromised, will attempt to take as much information as possible. This could mean excessive downloading or copying from corporate drives or exporting data from web interfaces or client apps. Obfuscation. Both cybercriminals and malicious insiders will be aware of the kinds of activity likely to trigger alarms and will take steps to avoid them. Changing file names and extensions, deleting logs and browsing history, and encrypting files are typical strategies. Exfiltration. With targets acquired and tracks covered, data exfiltration is then carried out by copying files to a personal cloud or removable storage device and sharing files with personal or burner email accounts. Defending from the inside out As we explained in our webinar series, while the initial stage of the attack chain focuses on keeping malicious actors outside our organization, the final two stages are far more concerned with what\'s happening inside it. Therefore, any effective defense must work from the inside out. It must detect and deter suspicious activity before data can slip past internal protections and be exposed to the outside world. Of course, data can do many things-but it cannot leave an organization on its own. Whether compromised, careless or malicious, a human is integral to any data loss incident. That\'s why traditional data loss prevention (DLP) tools are not as effective as they used to be. By focusing on the content of an incident, they only address a third of the problem. Instead, a comprehensive defense against data loss must merge content classification with threat telemetry and user behavior. Proofpoint Information Protection is the only solution that uses all three across channels in a unified, cloud-native interface. With this information, security teams can identify who is accessing and moving data-when, where and why. And | Tool Threat Cloud | ★★★ | |

2024-02-26 05:03:36 | Les tenants et aboutissants de la confidentialité des données, partie 2: confidentialité par conception en protection de l'information The Ins and Outs of Data Privacy, Part 2: Privacy by Design in Information Protection (lien direct) |
This is the second blog in a two-part series about data privacy. In our previous post, we discussed how data privacy has become increasingly important. And we covered why data loss protection (DLP) and insider threat management (ITM) tools are critical to ensuring data privacy. The shift to “work from anywhere” and the increase in cloud adoption have caused a rise in data loss and insider threats. To defend data from careless, malicious and compromised insiders-and the harm that they cause-security teams must implement data security tools like data loss prevention (DLP) and insider threat management (ITM) platforms. These tools monitor and control how employees interact with data. At the same time, companies are collecting more and more data about employees themselves, like protected health information (PHI). The abundance of all this data-which is being collected and processed in the cloud-creates a critical challenge for security teams. They must protect employee privacy without impeding productivity. In this post, we\'ll explore the topic of privacy by design, which aims to strike a balance between these two challenges. We\'ll cover why it\'s so important. And we\'ll discuss how Proofpoint Information Protection can help you build a modern DLP program and comply with data privacy laws. Why privacy by design matters for DLP and ITM Privacy by design is a framework that embeds privacy into the design of IT systems, infrastructure and business processes. Privacy is not an afterthought. It is considered right from the start-in the initial design phase. What\'s more, it\'s a core component that integrates visibility, transparency and user-centricity into its design. In short, privacy by design ensures that everything is built with the user in mind. Privacy by design is important to DLP and ITM because it helps to: Protect employee rights. Personal data is sacred. Employees expect their personal data to be safe and their rights protected. When a company takes a proactive, transparent approach to data privacy, it helps maintain trust with employees. Comply with privacy laws. Data privacy laws protect people by requiring businesses to keep their data safe and avoid sharing it unethically with third parties. These laws often require companies to tell users exactly how their data is used and collected, and to notify them in the event of a data breach. Failure to comply can lead to hefty fines and penalties, which can damage a firm\'s finances and brand image. Prevent bias in investigations. When user data is kept secure and private, it ensures insider threat investigations maintain their integrity and objectivity. If a user is identified, it could influence a security analyst\'s response to an incident. User privacy helps take emotion and subjectivity out of the picture. Ensure data privacy with Proofpoint DLP and ITM Proofpoint Information Protection includes administration and access controls. These controls can help your business keep data private and meet compliance requirements. Data residency and storage Proofpoint uses regional data centers in the U.S., Europe, Australia and Japan to meet data privacy and data residency requirements. You can control exactly where your data is stored at all of these data centers. For example, you can group your endpoints and map each group to a regional data center. This ensures that data on all those endpoints are stored in that regional center. So, a U.S. realm can manage U.S. endpoint data, which is sent to the U.S. data center. Attribute-based access controls Attribute-based access controls give you a flexible and easy way to manage access to data. You can use these controls to ensure that security analysts have visibility into data on a need-to-know basis only. For instance, you can write granular policies and assign access so that a U.S.-based security analyst can only see U.S. data. They cannot see data in Europe or the Asia-Pacific region. And when an analyst needs to access a specific user\'s data for an | Data Breach Tool Threat Cloud | ★★ | |

This blog is the first in a series where we explore data privacy. In these two blogs, we\'ll cover why data privacy is increasingly important as well as some tips for keeping data safe. We\'ll also discuss how data loss protection (DLP) and insider threat management tools (ITM) are critical to ensuring data privacy. Data Privacy Week in January 2024 highlighted the increasing importance and challenges of data privacy. Trends like digital transformation, remote work and the proliferation of cloud applications have made the task of protecting sensitive data harder than ever. As the volume and perceived value of data grows, so does the risk of data loss and theft, including by insiders. Despite these challenges, businesses can\'t afford missteps when it comes to keeping sensitive data safe. Companies everywhere are under pressure to meet strict data privacy laws that promote data security and data privacy. Noncompliance can be costly. Hefty fines and market loss are common. Research from our 2023 Voice of the CISO report underscores the risk. One-third of the CISOs who told us that their company suffered a material loss of sensitive data within the past 12 months also reported their business was hit with regulatory sanctions as a result. In this blog post, we take a closer look at data privacy and how it relates to data security. We also discuss how laws around data privacy are evolving. And we cover how data loss prevention (DLP) and insider threat management (ITM) tools can help you stay on top of your data compliance challenges. What is data privacy? Data privacy is about protecting sensitive data that belongs to individuals or entities. This includes personally identifiable information (PII), which can be used to identify an individual or a corporate customer. Examples of PII include names, addresses, Social Security or tax ID numbers, credit card data and dates of birth. A business that stores or manages this type of information must follow data privacy laws. These laws ensure that data is kept confidential and secure and that it is only used for authorized purposes. They are intended to help a business: Protect personal information Safeguard critical business data Preserve users\' autonomy Maintain trust with customers and employees Data privacy is also about trust. The misuse or theft of sensitive data can lead to email fraud, insurance fraud, identity theft and more. So, customers need to trust that the companies they share their private data with will guard it carefully. An evolving regulatory landscape Data privacy laws are designed to compel businesses to keep sensitive data safe. Data compliance mandates often require businesses to tell users exactly how their data is used and collected. They may also require companies to notify users when a data breach happens. As noted earlier, not following these laws can result in stiff penalties. Multiple data privacy laws around the globe govern regulations based on their type, the user\'s location and other criteria. Some examples include the: GDPR in the European Union CCPA in the U.S. HIPAA in the U.S. LGPD in Brazil Several state governments in the United States are stepping up efforts to enact data privacy laws. California, Colorado, Connecticut, Utah and Virginia enacted comprehensive consumer privacy laws before 2023. Those laws became enforceable last year. In 2023, these states enacted privacy laws: Delaware Florida Indiana Iowa Montana Oregon Tennessee Texas As data privacy laws emerge or evolve, the definition of sensitive data may change. For example, GDPR expanded the definition of PII to include data elements like email and IP addresses. That is why it is so important for companies to stay attuned to this ever-changing landscape. The rise of generative AI sites has also sparked new concerns about data privacy. New laws are likely to be developed soon. The Biden Administration\'s new executive order will also have an impact on data use in the year ahead. Why | Data Breach Malware Tool Threat Cloud | ★★ | |

2024-02-12 08:02:39 | 4 étapes pour empêcher le compromis des e-mails des fournisseurs dans votre chaîne d'approvisionnement 4 Steps to Prevent Vendor Email Compromise in Your Supply Chain (lien direct) |
Supply chains have become a focal point for cyberattacks in a world where business ecosystems are increasingly connected. Email threats are a significant risk factor, as threat actors are keen to use compromised email accounts to their advantage. Every month, a staggering 80% of Proofpoint customers face attacks that originate from compromised vendor, third-party or supplier email accounts. Known as supplier account compromise, or vendor email compromise, these attacks involve threat actors infiltrating business communications between trusted partners so that they can launch internal and external attacks. Their ultimate goal might be to steal money, steal data, distribute malware or simply cause havoc. In this blog post, we\'ll explain how vendor emails are compromised and how you can stop these attacks. Finally, we\'ll tell you how Proofpoint can help. What\'s at stake Supply chain compromise attacks can be costly for businesses. IBM, in its latest Cost of a Data Breach Report, says that the average total cost of a cyberattack that involves supply chain compromise is $4.76 million. That is almost 12% higher than the cost of an incident that doesn\'t involve the supply chain. In addition to the financial implications, compromised accounts can lead to: Phishing scams that result in even more compromised accounts Reputational and brand damage Complex legal liabilities between business partners How does vendor email compromise occur? Supply chain compromise attacks are highly targeted. They can stretch out over several months. And typically, they are structured as a multistep process. The bad actor initiates the assault by gaining access to the email account of a vendor or supplier through various means. Phishing attacks are one example. Once the attacker gains access, they will lay low for an extended period to observe the vendor\'s email communications. During this time, the adversary will study the language and context of messages so that they can blend in well and avoid detection. Attackers might also use this observation period to establish persistence. They will create mail rules and infrastructure so that they can continue to receive and send messages even after the vendor has regained control of the account. Once they establish access and persistence, the attackers will begin to insert themselves into conversations within the supplier\'s company as well as with external partners and customers. By posing as the sender, the attacker takes advantage of established trust between parties to increase their chances of success. Overview of a vendor email compromise attack. Proofpoint has observed a growing trend of attackers targeting accounts within smaller businesses and using them to gain entry into larger companies. Threat actors often assume that small businesses have less protection than large companies. They see them as targets that can help them achieve a bigger payday. How to stop vendor email compromise If you want to defend against these attacks, it\'s critical to understand the methods behind them. Such a formidable problem requires a strategic and multilayered solution. The four broad steps below can help. Step 1: Know your suppliers Your first line of defense against these email attacks sounds simple, but it\'s challenging. It is the ability to intimately “know your supplier” and understand their security strategy. This requires more than a one-time vendor assessment. Your security teams will need to prioritize continuous monitoring of your company\'s business partnerships. On top of that knowledge, you need a thorough understanding of the access and privileges that your business grants to each vendor.

2024-02-12 07:37:05 | Alerte communautaire: campagne malveillante en cours impactant les environnements cloud Azure Community Alert: Ongoing Malicious Campaign Impacting Azure Cloud Environments (lien direct) |
Over the past weeks, Proofpoint researchers have been monitoring an ongoing cloud account takeover campaign impacting dozens of Microsoft Azure environments and compromising hundreds of user accounts, including senior executives. This post serves as a community warning regarding the attack and offers suggestions that affected organizations can implement to protect themselves from it. What are we seeing? In late November 2023, Proofpoint researchers detected a new malicious campaign, integrating credential phishing and cloud account takeover (ATO) techniques. As part of this campaign, which is still active, threat actors target users with individualized phishing lures within shared documents. For example, some weaponized documents include embedded links to “View document” which, in turn, redirect users to a malicious phishing webpage upon clicking the URL. Threat actors seemingly direct their focus toward a wide range of individuals holding diverse titles across different organizations, impacting hundreds of users globally. The affected user base encompasses a wide spectrum of positions, with frequent targets including Sales Directors, Account Managers, and Finance Managers. Individuals holding executive positions such as “Vice President, Operations”, "Chief Financial Officer & Treasurer" and "President & CEO" were also among those targeted. The varied selection of targeted roles indicates a practical strategy by threat actors, aiming to compromise accounts with various levels of access to valuable resources and responsibilities across organizational functions. Following the attack\'s behavioral patterns and techniques, our threat analysts identified specific indicators of compromise (IOCs) associated with this campaign. Namely, the use of a specific Linux user-agent utilized by attackers during the access phase of the attack chain: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/120.0.0.0 Safari/537.36 Attackers predominantly utilize this user-agent to access the \'OfficeHome\' sign-in application along with unauthorized access to additional native Microsoft365 apps, such as: \'Office365 Shell WCSS-Client\' (indicative of browser access to Office365 applications) \'Office 365 Exchange Online\' (indicative of post-compromise mailbox abuse, data exfiltration and email threats proliferation) \'My Signins\' (used by attackers for MFA manipulation; for more info about this technique, see our recent Cybersecurity Stop of the Month blog) \'My Apps\' \'My Profile\' Post compromise risks Successful initial access often leads to a sequence of unauthorized post-compromise activities, including: MFA manipulation. Attackers register their own MFA methods to maintain persistent access. We have observed attackers choosing different authentication methods, including the registration of alternative phone numbers for authentication via SMS or phone call. However, in most MFA manipulation instances, attackers preferred to add an authenticator app with notification and code. Examples of MFA manipulation events, executed by attackers in a compromised cloud tenant. Data exfiltration. Attackers access and download sensitive files, including financial assets, internal security protocols, and user credentials. Internal and external phishing. Mailbox access is leveraged to conduct lateral movement within impacted organizations and to target specific user accounts with personalized phishing threats. Financial fraud. In an effort to perpetrate financial fraud, internal email messages are dispatched to target Human Resources and Financial departments within affected organizations. Mailbox rules. Attackers create dedicated obfuscation rules, intended to cover their tracks and erase all evidence of malicious activity from victims\' mailboxes. Examples of obfuscation mailbox rules created by attackers following successful account takeover.

2024-02-05 11:41:18 | 7 conseils pour développer une approche proactive pour éviter le vol de données 7 Tips to Develop a Proactive Approach to Prevent Data Theft (lien direct) |
Data is one of the most valuable assets for a modern enterprise. So, of course, it is a target for theft. Data theft is the unauthorized acquisition, copying or exfiltration of sensitive information that is typically stored in a digital format. To get it, bad actors either abuse privileges they already have or use various other means to gain access to computer systems, networks or digital storage devices. The data can range from user credentials to personal financial records and intellectual property. Companies of all sizes are targets of data theft. In September 2023, the personal data of 2,214 employees of the multinational confectionary firm The Hershey Company was stolen after a phishing attack. And in January 2024, the accounting firm of Framework Computer fell victim to an attack. A threat actor posed as the Framework\'s CEO and convinced the target to share a spreadsheet with the company\'s customer data. Data thieves aim to profit financially, disrupt business activities or do both by stealing high-value information. The fallout from a data breach can be very costly for a business-and the cost is going up. IBM reports that the global average cost of a data breach in 2023 was $4.45 million, a 15% increase over three years. Other data suggests that the average cost of a breach is more than double for U.S. businesses-nearly $9.5 million. Not all data breaches involve data theft, but stealing data is a top aim for many attackers. Even ransomware gangs have been shifting away from data encryption in their attacks, opting instead to steal massive amounts of data and use its value as a means to compel businesses to pay ransom. So, what can businesses do to prevent data theft? Taking a proactive approach toward stopping someone from stealing your data is a must. This blog post can help jump-start your thinking about how to improve data security. We explore how data theft happens and describe some common threats that lead to it. We also outline seven strategies that can help reduce your company\'s risk of exposure to data theft and highlight how Proofpoint can bolster your defenses. Understanding data theft-and who commits it Data theft is a serious security and privacy breach. Data thieves typically aim to steal information like: Personally identifiable information (PII) Financial records Intellectual property (IP) Trade secrets Login credentials Once they have it, bad actors can use stolen data for fraudulent activities or, in the case of credential theft, to gain unlawful access to accounts or systems. They can also sell high-value data on the dark web. The consequences of data theft for businesses can be significant, if not devastating. They include hefty compliance penalties, reputational damage, and financial and operational losses. Take the manufacturing industry as an example. According to one source, a staggering 478 companies in this industry have experienced a ransomware attack in the past five years. The costs in associated downtime are approximately $46.2 billion. To prevent data theft, it\'s important to recognize that bad actors from the outside aren\'t the only threat. Insiders, like malicious employees, contractors and vendors, can also steal data from secured file servers, database servers, cloud applications and other sources. And if they have the right privileges, stealing that data can be a breeze. An insider\'s goals for data theft may include fraud, the disclosure of trade secrets to a competitor for financial gain, or even corporate sabotage. As for how they can exfiltrate data, insiders can use various means, from removable media to personal email to physical printouts. How does data theft happen? Now, let\'s look at some common methods that attackers working from the outside might employ to breach a company\'s defenses and steal data. Phishing. Cybercriminals use phishing to target users through email, text messages, phone calls and other forms of communication.

2024-02-02 05:00:40 | Brisez la chaîne d'attaque: le gambit d'ouverture Break the Attack Chain: The Opening Gambit (lien direct) |
The threat landscape has always evolved. But the pace of change over the last decade is unlike anything most security professionals have experienced before. Today\'s threats focus much less on our infrastructure and much more on our people. But that\'s not all. Where once a cyberattack may have been a stand-alone event, these events are now almost always multistage. In fact, most modern threats follow the same playbook: initial compromise, lateral movement and impact. While this approach has the potential to cause more damage, it also gives security teams more opportunities to spot and halt cyberattacks. By placing protections in key spots along the attack chain, we can thwart and frustrate would-be cybercriminals before their ultimate payoff. This starts with understanding the opening gambit: How do threat actors attempt to gain access to your king-in this case, your networks and data? And what can be done to keep them at bay? Understanding the playbook The chess parallels continue when we look at recent evolutions in the threat landscape, with our defensive tactics provoking an adapted method of attack. We see this in full effect when it comes to multifactor authentication (MFA). In recent years, security professionals have flocked to MFA to protect accounts and safeguard credentials. In response, threat actors have developed MFA bypass and spoofing methods to get around and weaponize these protections. So much so that MFA bypass can now be considered the norm when it comes to corporate credential phishing attacks. Increasingly, cybercriminals purchase off-the-shelf kits which enable them to use adversary-in-the-middle (AiTM) tactics to digitally eavesdrop and steal credentials. We have also seen an increase in other human-activated methods, such as telephone-oriented attack delivery (TOAD). This method combines voice and email phishing techniques to trick victims into disclosing sensitive information such as login credentials or financial data. Whatever the method, the desired outcome at this stage is the same. Cybercriminals seek to get inside your defenses so they can execute the next stage of their attack. That is what makes the opening gambit such a critical time in the lifecycle of a cyber threat. Modern threat actors are experts at remaining undetected once they are inside our networks. They know how to hide in plain sight, move laterally and escalate privileges. So, if this stage of the attack is a success, organizations have a huge problem. The good news is that the more we understand the tactics that today\'s cybercriminals use, the more we can adapt our defenses to stop them in their tracks before they can inflict significant damage. Countering the gambit The best opportunity to stop cybercriminals is before and during the initial compromise. By mastering a counter to the opening gambit, we can keep malicious actors where they belong-outside our perimeter. It will surprise no one that most threats start in the inbox. So, the more we can do to stop malicious messaging before it reaches our people, the better. There is no silver bullet in this respect. artificial intelligence (AI)-powered email security is as close as it gets. Proofpoint Email Protection is the only AI and machine learning-powered threat protection that disarms today\'s advanced attacks. Proofpoint Email Protection uses trillions of data points to detect and block business email compromise (BEC), phishing, ransomware, supply chain threats and plenty more. It also correlates threat intelligence across email, cloud and network data to help you stay ahead of new and evolving threats that target your people. However, the difficult reality is that nothing is entirely impenetrable. Today\'s security teams must assume some threats will reach the inbox. And your people need to be prepared when they do. Equipping this vital line of defense requires total visibility into who is being attacked in your organization-and when, where and how.

Engineering Insights is an ongoing blog series that gives a behind-the-scenes look into the technical challenges, lessons and advances that help our customers protect people and defend data every day. Each post is a firsthand account by one of our engineers about the process that led up to a Proofpoint innovation. In this blog post, we discuss the Domain Relationship Policy Framework (DRPF)-an effort that has been years in the making at Proofpoint. The DRPF is a simple method that is used to identify verifiably authorized relationships between arbitrary domains. We create a flexible way to publish policies. These policies can also describe complex domain relationships. The details for this new model require in-depth community discussions. These conversations will help us collectively steer the DRPF toward becoming a fully interoperable standard. We are now in the early proposal stage for the DRPF, and we are starting to engage more with the broader community. This post provides a glimpse down the road leading to standardization for the DRPF. Why Proofpoint developed DRPF To shine a light on why Proofpoint was inspired to develop the DRPF in the first place, let\'s consider the thinking of the initial designers of the Domain Name System (DNS). They assumed that subdomains would inherit the administrative control of their parent domains. And by extension, this should apply to all subsequent subdomains down the line. At the time, this was reasonable to assume. Most early domains and their subdomains operated in much the same way. For example, “university.edu” directly operated and controlled the administrative policies for subdomains such as “lab.university.edu” which flowed down to “project.lab.university.edu.” Since the mid-1980s, when DNS was widely deployed, there has been a growing trend of delegating subdomains to third parties. This reflects a breakdown of the hierarchical model of cascading policies. To see how this works, imagine that a business uses “company.com” as a domain. That business might delegate “marketing.company.com” to a third-party marketing agency. The subdomain must inherit some policies, while the subdomain administrator may apply other policies that don\'t apply to the parent domain. Notably, there is no mechanism yet for a domain to declare a relationship with another seemingly independent domain. Consider a parent company that operates multiple distinct brands. The company with a single set of policies may want them applied not only to “company.com” (and all of its subdomains). It may also want them applied to its brand domains “brand.com” and “anotherbrand.com.” It gets even more complex when any of the brand domains delegate various subdomains to other third parties. So, say some of them are delegated to marketing or API support. Each will potentially be governed by a mix of administrative policies. In this context, “policies” refers to published guidance that is used when these subdomains interact with the domain. Policies might be for information only. Or they might provide details that are required to use services that the domain operates. Most policies will be static (or appear so to the retrieving parties). But it is possible to imagine that they could contain directives akin to smart contracts in distributed ledgers. 3 Design characteristics that define DRPF The goal of the DRPF is to make deployment and adoption easier while making it flexible for future use cases. In many prior proposals, complex requirements bogged down efforts to get rid of administrative boundaries between and across disparate domains. Our work should be immediately useful with minimal effort and be able to support a wide array of ever-expanding use cases. In its simplest form, three design characteristics define the DRPF: A domain administrator publishes a policy assertion record for the domain so that a relying party can discover and retrieve it. The discovered policy assertion directs the relying party to where they can find | Tool Prediction Cloud Technical | ★★★ | |

2024-01-17 06:00:02 | Comment mettre en place un programme de gestion des menaces d'initié et de prévention des pertes de données How to Set Up an Insider Threat Management and Data Loss Prevention Program (lien direct) |
This blog post is adapted from our e-book, Getting Started with DLP and ITM. The last few years have brought unprecedented change. An increasingly distributed workforce, access to more data through more channels and a shift to the cloud have transformed the nature of work. These trends have made protecting sensitive data more complicated and demanding. What\'s clear is that organizations are struggling to rise to the challenge. Between 2020 and 2022, insider threats increased by a staggering 44%. And the costs of addressing them increased 34%-from $11.45 million to $15.38 million. This upswing mainly comes down to two factors. For starters, most security teams have little visibility into people-caused data loss and insider-led security incidents. And few have the tools or resources to handle it. That\'s why Gartner sees platforms for data loss prevention and insider threat management (DLP and ITM) increasingly converging. Businesses need tools and processes that give them holistic, contextualized insights that take user behavior into account. It\'s no longer enough to focus on data-and where it\'s moving. To prevent data loss, industry leaders need to take a people-centric approach that expands beyond traditional drivers like compliance. In this blog post, we\'ll explore some basics for designing an ITM and DLP program. This can help you approach information protection in a way that\'s built for how modern organizations work. Why information protection is so challenging Risks are everywhere in today\'s complex landscape. Here are a few changes making it difficult for companies to protect their data. More data is open to exposure and theft. As businesses go digital, more data is being generated than ever before. According to IDC\'s Worldwide Global DataSphere Forecast, the total amount of data generated data will double from 2022 to 2026. That means malicious insiders will have more access to more sensitive data through more channels. It will also be easier for careless users to expose data inadvertently. Plus, any security gap between channels, any misconfiguration or any accidental sharing of files can give external attackers more opportunities to steal data. New data types are hard to detect. Data isn\'t just growing in volume. It\'s also becoming more diverse, which makes it harder to detect and control. With traditional DLP program tools, data typically fits within very tightly defined data patterns (such as payment card number). But even then, it generates too many false positives. Now, key business data is more diverse and can be graphical, tabular or even source code. The network security perimeter no longer exists. With more employees and contractors working remotely, the security perimeter has shifted from brick and mortar to one based on people. Add to the mix bring-your-own-device (BYOD) practices, where the personal and professional tend to get blurred, and security teams have even more risks to contend with. In a survey for the 2023 State of the Phish report from Proofpoint, 72% of respondents said they use one or more of their personal devices for work. Employee churn is high. Tech industry layoffs in 2022 and 2023 have seen many employees leaving and joining businesses at a rapid rate. The result is greater risk of data exfiltration, infiltration and sabotage. Security leaders know it, too-39% of chief information security officers rated improving information protection as the top priority over the next two years. Security talent is in short supply. A lack of talent has left many security teams under-resourced. And the situation is likely to get worse. In 2023, the cybersecurity workforce gap hit an all-time high-there are 4 million more jobs than there are skilled workers. DLP vs. ITM What\'s the difference between DLP and ITM? Both DLP and ITM work to prevent data loss. But they achieve it in different ways.

Cybercriminals are constantly innovating so that they can infiltrate your systems and steal your valuable data. They do this through a complex multi-stage method commonly known as the attack chain. During the initial compromise, attackers use advanced email threats like phishing scams, malware attachments, business email compromise (BEC) and QR code threats to get a foothold in your systems. That\'s why email security tools typically focus on stopping these threats. Steps in the attack chain. But no technology is foolproof. Inevitably, some emails will get through.

It\'s easy to understand why insider threats are one of the top cybersecurity challenges for security leaders. The shift to remote and hybrid work combined with data growth and cloud adoption has meant it\'s easier than ever for insiders to lose or steal data. Legacy systems simply don\'t provide the visibility into user behavior that\'s needed to detect and prevent insider threats. With so much potential for brand and financial damage, insider threats are now an issue for the C-suite. As a result, businesses are on the lookout for tools that can help them to better manage these threats. To help businesses understand what to look for, Gartner has recently released Market Guide for Insider Risk Management Solutions. In this report, Gartner explores what security and risk leaders should look for in an insider risk management (IRM) solution. It also provides guidance on how to implement a formal IRM program. Let\'s dive into some of its highlights. Must-have capabilities for IRM tools Gartner states that IRM “refers to the use of technical solutions to solve a fundamentally human problem.” And it defines IRM as “a methodology that includes the tools and capabilities to measure, detect and contain undesirable behavior of trusted accounts in the organization.” Gartner identifies three distinct types of users-careless, malicious and compromised. That, we feel, is in line with our view at Proofpoint. And the 2022 Cost of Insider Threats Global Report from Ponemon Institute notes that most insider risks can be attributed to errors and carelessness, followed by malicious and compromised users. In its Market Guide, Gartner identifies the mandatory capabilities of enterprise IRM platforms: Orchestration with other cybersecurity tooling Monitoring of employee activity and assimilating into a behavior-based risk model Dashboarding and alerting of high-risk activity Orchestration and initiation of intervention workflows This is the third consecutive year that Proofpoint is a Representative Vendor in the Market Guide. Proofpoint was an early and established leader in the market for IRM solutions. Our platform: Integrates with a broad ecosystem of cybersecurity tools. Our API-driven architecture means it\'s easy for you to feed alerts into your security tools. That includes security information and event management (SIEM) as well as SOAR and service management platforms, such as Splunk and ServiceNow. That, in turn, helps you gain a complete picture of potential threats. Provides a single lightweight agent with a dual purpose. With Proofpoint, you get the benefit of data loss prevention (DLP) and ITM in a single solution. This helps you protect against data loss and get deep visibility into user activities. With one agent, you can monitor everyday users. That includes low-risk and regular business users, risky users, such as departing employees, privileged users and targeted users. Offers one centralized dashboard. This saves you time and effort by allowing you to monitor users, correlate alerts and triage investigations from one place. You no longer need to waste your time switching between tools. You can quickly see your riskiest users, top alerts and file exfiltration activity in customizable dashboards. Includes tools to organize and streamline tasks. Proofpoint ITM lets you change the status of events with ease, streamline workflows and better collaborate with team members. Plus, you can add tags to help group and organize your alerts and work with more efficiency. DLP and IRM are converging In its latest Market Guide, Gartner says: “Data loss prevention (DLP) and insider risk strategies are increasingly converging into a unified solution. The convergence is driven by the recognition that preventing data loss and managing insider risks are interconnected goals.” A legacy approach relies on tracking data activity. But that approach is no longer sufficient because the modern way of working is more complex. Employees and third parties have access to more data than ever before.

As a new year approaches, it is natural to reflect on recent accomplishments. At Proofpoint, we are reflecting on our work to deliver security awareness content and updated features in line with our ongoing goal to drive behavior change. Proofpoint Security Awareness integrates our rich threat intelligence, which means it taps into current and emerging attacks. Our threat analysts surface threat trends, such as artificial intelligence (AI)-enhanced vishing, malicious QR codes and remote IT support scams. And then we work quickly to release new training features and awareness material to ensure inform security administrators and educate employees about ever-evolving attacks. In 2023, our content releases focused on three areas: Delivering a threat-driven program Improving how security awareness administrators work Enhancing how people learn Let\'s review the past year and explore how Proofpoint used content releases to respond to the changing threat landscape. Image from AI Chatbot Threats training (play video). Quick turnaround for threat trends Proofpoint Security Awareness alerts customers to threats in two powerful ways-Threat Alerts and Attack Spotlights. It also continuously trains employees with threat-driven training modules. Threat Alerts These weekly releases focus on a specific and current ongoing attack. They explain what the threat is and who it might target. And they describe a specific lure, if applicable. Each alert is linked to activity that our threat analysts see happening in the wild. We recommend applicable training like simulated phishing and awareness material and include suggested email messaging. In 2023, we released Threat Alerts on: IRS-themed phishing lures for tax season (February, March, April) AI-enhanced vishing calls that impersonate loved ones (March) Malicious QR codes for credential phishing (May, August) Telephone-oriented attack delivery (TOAD) using a Geek Squad PDF lure (July, October) Charity donation scams around the Israel-Palestine crisis (October) Christmas party lures for credential phishing (November) Attack Spotlights These monthly releases cast a wider lens on attack types. They focus on a time-based or reoccurring threat that is expected to trend, typically related to holidays, travel seasons or shopping events. Each spotlight is released a month in advance with a campaign plan, awareness material and training modules, and is available in 12 core languages. In 2023, Proofpoint published these Attack Spotlight campaigns: Smishing with package delivery lures (February) Business email compromise (BEC) phishing with requests for quotations (RFQs) (April) LinkedIn phishing lures (May) Amazon phishing lures (June) Remote IT support scams (September) Gift card scams (December) Image from Attack Spotlight video (play video). Threat modules These training videos are relevant to the changing threat landscape. They are inspired by our threat intelligence and our team\'s threat landscape research. These micro-learning modules are grounded in learning science principles that are designed to drive behavior change. Each module has a concise and specific learning objective. The delivery of content is tailored to individual factors such as a person\'s role, learning style, vulnerability level and preferred language. In 2023, we covered these topics in our new threat training modules: Data loss protection AI chatbot threats Amazon phishing scams Cryptocurrency investment scams QR code dangers Multifactor authentication (MFA) Image from Threat Module video (play video).

2024-01-04 06:00:10 | Cybersecurity Stop of the Month: MFA Manipulation (lien direct) | This blog post is part of a monthly series exploring the ever-evolving tactics of today\'s cybercriminals. Cybersecurity Stop of the Month focuses on the critical first three steps in the attack chain in the context of email threats. The series is designed to help you understand how to fortify your defenses to protect people and defend data against emerging threats in today\'s dynamic threat landscape. The critical first three steps of the attack chain: reconnaissance, initial compromise and persistence. So far in this series, we have covered the following types of attacks: Supplier compromise EvilProxy SocGholish eSignature phishing QR code phishing Telephone-oriented attack delivery (TOAD) Payroll diversion In this post, we examine an attack technique called multifactor (MFA) manipulation. This malicious post-compromise attack poses a significant threat to cloud platforms. We cover the typical attack sequence to help you understand how it works. And we dive deeper into how Proofpoint account takeover capabilities detected and prevented one of these threats for our customer. Background MFA manipulation is an advanced technique where bad actors introduce their own MFA method into a compromised cloud account. These attackers are used after a cloud account takeover attack, or ATO. ATOs are an insidious threat that are alarmingly common. Recent research by Proofpoint threat analysts found that in 2023 almost all businesses (96%) were targeted by cloud-based attacks. What\'s more, a whopping 60% were successfully compromised and had at least one account taken over. MFA manipulation attacks can work several ways with bad actors having multiple options for getting around MFA. One way is to use an adversary-in-the-middle (AiTM) attack. This is where the bad actor inserts a proxy server between the victim and the website that they\'re trying to log into. Doing so enables them to steal that user\'s password as well as the session cookie. There\'s no indication to the user that they\'ve been attacked-it just seems like they\'ve logged into their account as usual. However, the attackers have what they need to establish persistence, which means they can maintain access even if the stolen MFA credentials are revoked or deemed invalid. The scenario Recently, Proofpoint intercepted a series of MFA manipulation attacks on a large real estate company. In one case, the bad actors used an AiTM attack to steal the credentials of the firm\'s financial controller as well as the session cookie. Once they did that, they logged into that user\'s business account and generated 27 unauthorized access activities. The threat: How did the attack happen? Here is a closer look at how this MFA manipulation attack played out: 1. Bad actors used the native “My Sign-Ins” app to add their own MFA methods to compromise Microsoft 365 accounts. We observed that the attackers registered their own authenticator app with notification and code. They made this move right after they gained access to the hijacked account as part of an automated attack flow execution. This, in turn, allowed them to secure their foothold within the targeted cloud environment. The typical MFA manipulation flow using Microsoft\'s “My Sign-Ins” app. 2. After the compromise, the attackers demonstrated a sophisticated approach. They combined MFA manipulation with OAuth application abuse. With OAuth abuse, an attacker authorizes and/or uses a third-party app to steal data, spread malware or execute other malicious activities. Attackers also use the abused app to maintain persistent access to specific resources even after their initial access to a compromised account has been cut off. 3. The attackers authorized the seemingly benign application, “PERFECTDATA SOFTWARE,” to gain persistent access to the user\'s account and the systems, as well as the resources and applications that the user could access. The permissions the attackers requested for this app included: | Malware Tool Vulnerability Threat Cloud | ★★★ | |

2023-12-28 14:18:07 | Concevoir un indice de texte mutable à l'échelle de la pétaoctet rentable Designing a Cost-Efficient, Petabyte-Scale Mutable Full Text Index (lien direct) |
Engineering Insights is an ongoing blog series that gives a behind-the-scenes look into the technical challenges, lessons and advances that help our customers protect people and defend data every day. Each post is a firsthand account by one of our engineers about the process that led up to a Proofpoint innovation. At Proofpoint, running a cost-effective, full-text search engine for compliance use cases is an imperative. Proofpoint customers expect to be able to find documents in multi-petabyte archives for legal and compliance reasons. They also need to index and perform searches quickly to meet these use cases. However, creating full-text search indexes with Proofpoint Enterprise Archive can be costly. So we devote considerable effort toward keeping those costs down. In this blog post, we explore some of the ways we do that while still supporting our customers\' requirements. Separating mutable and immutable data One of the most important and easiest ways to reduce costs is to separate mutable and immutable data. This approach doesn\'t always fit every use case, but for the Proofpoint Enterprise Archive it fits well. For archiving use cases-and especially for SEC 17a-4 compliance-data that is indexed can\'t be modified. That includes data-like text in message bodies and attachments. The Proofpoint Enterprise Archive has features that require the storage and mutation of data alongside a message, in accordance with U.S. Securities and Exchange Commission (SEC) compliance. (For example, to which folders a message is a member, and to which legal matters a message pertains.) To summarize, we have: Large immutable indexes Small mutable indexes By separating data into mutable and immutable categories, we can index these datasets separately. And we can use different infrastructure and provisioning rules to manage that data. The use of different infrastructure allows us to optimize the cost independently. Comparing the relative sizes of mutable and immutable indexes. Immutable index capacity planning and cost Normally, full-text search indexes must be provisioned to handle the load of initial write operations, any subsequent update operations and read operations. By indexing immutable data separately, we no longer need to provision enough capacity to handle the subsequent update operations. This requires less IO operations overall. To reduce IO needs further, the initial index population is managed carefully with explicit IO reservation. Sometimes, this will mean adding more capacity (nodes/servers/VMs) so that the IO needs of existing infrastructure are not overloaded. When you mutate indexes, it is typically best practice to leave an abundance of disk space to support the index merge operations when updates occur. In some cases, this can be as much as 50% free disk space. But with immutable indexes, you don\'t need to have so much spare capacity-and that helps to reduce costs. In summary, the following designs can help keep costs down: Reduce IO needs because documents do not mutate Reduce disk space requirements because free space for mutation isn\'t needed Careful IO planning on initial population, which reduces IO requirements Mutable index capacity planning and cost Meanwhile, mutable indexes benefit from standard practices. They can\'t receive the same reduced capacity as immutable indexes. However, given that they\'re a fraction of the size, it\'s a good trade-off. Comparing the relative free disk space of mutable and Immutable indexes. Optimized join with custom partitioning and routing In a distributed database, join operations can be expensive. We often have 10s to 100s of billions of documents for the archiving use case. When both sides of the join operation have large cardinality, it\'s impractical to use a generalized approach to join the mutable and immutable data. To make this high-cardinality join practical, we partition the data in the same way for both the mutable and immutable data. As a result, we end up with a one-t | Cloud Technical | ★★★ | |

2023-12-27 09:19:46 | 3 incontournables des performances de recherche d'archives: une comparaison de logiciels d'archives de messagerie 3 Must-Haves of Archive Search Performance: An Email Archive Software Comparison (lien direct) |
Yes, it\'s true that customers who use legacy on-premises archives or even modern cloud solutions say “fast search performance” is a primary reason to migrate to Proofpoint Archive. Our customers often highlight “fast search performance” as a key email archiving solution element. For reference, look no further than Gartner Peer Insights, where “search/index” is ranked the highest out of product feature areas evaluated by our customers. However, you don\'t buy a Tesla Model X just for its top speed. You don\'t purchase a Rolex just to tell time. And you don\'t subscribe to or license an archive just for its search performance. Of course, not having adequate search performance can spell dire consequences when you need to address e-discovery requests. Think of having to settle a lawsuit early because you can\'t get search results in time to determine whether it makes better sense to litigate. But there\'s more to email archive search performance than just speed. In this blog, we\'ll explore three factors that drive positive outcomes for our customers. Speed is one, and the other two are scalability and ease of use. 1: Speed When you run a search for specific information in your email archive, how long does it take to retrieve that information? Hours? Days? Longer? Search speed dictates how fast you receive results from a search. While some vendor email archiving tools are incredibly slow, Proofpoint Archive has a financially backed search service-level agreement (SLA) that obligates us to return search results in seconds, on average, for our customers. To give you with some context, here\'s what we found when we compared the email archive search speeds of Microsoft Purview eDiscovery and Proofpoint Archive-specifically when searching 100 mailboxes and 50,000 mailboxes. For this example, a total of 200 searches were run, based on an average of 10 cases managed per month with each case requiring 20 searches to be performed. Microsoft doesn\'t have search performance SLAs. But they provide “guidelines for average search time” based on the number of mailboxes searched. (See the table below.) Guidelines for average search times for Microsoft Purview eDiscovery solutions. Based on internal, anonymous archive usage reports, as of August 2023 the average search time for Proofpoint Archive was 3.28 seconds. Also, it\'s estimated that Microsoft will take about 1.67 hours to return results when searching 100 mailboxes. Proofpoint Archive returned results in about 0.18 hours, as shown below. A comparison of search speed between Microsoft and Proofpoint. At this level of searching, the search speed difference may not seem significant. However, if you factor in rerunning searches due to new data or a system failure (like index corruption) with Microsoft, the numbers can grow rapidly. The search speed expectation with Proofpoint remains consistent, given our average search performance, particularly when you run consecutive searches. The search speed difference becomes more noteworthy when you consider highly litigious organizations that need to run hundreds or thousands of searches across hundreds or thousands of mailboxes. In the second scenario, when searching 50,000 mailboxes, it\'s estimated that Microsoft will take about 66.67 hours to return search results. That\'s like having your team “babysit” Microsoft e-discovery searches for more than a week and a half every month! Separately, Proofpoint Archive is expected to remain the same at 0.18 hours. With Proofpoint, you get search results from the archive when you need them, helping to improve your ability to respond to e-discovery requests and internal investigations in a timely fashion. 2: Scalability When you address an e-discovery request, do you run only one search? Probably not. The factor of search scalability defines your ability to achieve your expected search speed performance time and time again, regardless of whether you\'re searching 100 mailboxes or 50,000 mailboxes-and regardless of | Tool Cloud | ★★★ | |

2023-12-14 09:44:32 | Atténuation des menaces d'initié: 5 meilleures pratiques pour réduire le risque Insider Threat Mitigation: 5 Best Practices to Reduce Risk (lien direct) |
(This is an updated version of a blog that was originally published on 1/28/21.) Most security teams focus on detecting and preventing external threats. But not all threats come from the outside. The shift to hybrid work, accelerated cloud adoption and high rates of employee turnover have created a perfect storm for data loss and insider threats over the past several years. Today, insider threats rank amongst the top concerns for security leaders-30% of chief information security officers report that insider threats are their biggest cybersecurity threat over the next 12 months. It\'s easy to understand why. Insider threats have increased 44% since 2020 due to current market dynamics-and security teams are struggling to keep pace. According to the Verizon 2023 Data Breach Investigations Report, 74% of all breaches involve the human element. In short, data doesn\'t lose itself. People lose it. When the cybersecurity risk to your company\'s vital systems and data comes from the inside, finding ways to mitigate it can be daunting. Unlike with tools that combat external threats, security controls for data loss and insider threats can impact users\' daily jobs. However, with the right approach and insider threat management tools, that doesn\'t have to be the case. In this blog post, we\'ll share best practices for insider threat mitigation to help your business reduce risk and overcome common challenges you might face along the way. What is an insider threat? But first, let\'s define what we mean by an insider threat. In the cybersecurity world, the term “insider” describes anyone with authorized access to a company\'s network, systems or data. In other words, it is someone in a position of trust. Current employees, business partners and third-party contractors can all be defined as insiders. As part of their day-to-day jobs, insiders have access to valuable data and systems like: Computers and networks Intellectual property (IP) Personal data Company strategy Financial information Customer and partner lists All insiders pose a risk given their position of trust-but not all insiders are threats. An insider threat occurs when someone with authorized access to critical data or systems misuses that access-either on purpose or by making a mistake. The fallout from an insider threat can be dire for a business, including IP loss, legal liability, financial consequences and reputational damage. The challenge for security firms is to determine which insiders are threats, and what type of threats they are, so they know how to respond. There are three insider threat types: Careless. This type of risky insider is best described as a user with good intentions who makes bad decisions that can lead to data loss. The 2022 Cost of Insider Threats Global Report from Ponemon Institute notes that careless users account for more than half (56%) of all insider-led incidents. Malicious. Some employees-or third parties, like contractors or business partners-are motivated by personal gain. Or they might be intent on harming the business. In either case, these risky users might want to exfiltrate trade secrets or take IP when they leave the company. Industrial espionage and sabotage are examples of malicious insider activity. Ponemon research shows malicious insiders account for 26% of insiders. Compromised. Sometimes, external threat actors steal user login information or other credentials. They then use those credentials to access applications and systems. Ponemon reports that compromised users account for 18% of insiders. Insider threat mitigation best practices Companies can minimize brand and financial damage by detecting and stopping insider threats. How each security team approaches insider threats will vary depending on the industry, maturity and business culture. However, every organization can use the five best practices we\'ve outlined below to improve their insider threat prevention. 1.

2023-12-14 09:00:56 | La détection de code QR malveillant fait un bond en avant géant Malicious QR Code Detection Takes a Giant Leap Forward (lien direct) |
Proofpoint introduces inline, pre-delivery QR code detection engine to help protect against imaged-based QR code phishing attacks QR code phishing, also known as quishing, is the latest attack hitting inboxes. This emerging threat is able to get around traditional email defenses and is forging a new way to deliver email attacks directly to users. Along with email phishing, executive impersonation, spear phishing and business email compromise (BEC), this threat has become one of the top concerns for security and IT teams. In response, Proofpoint has launched new inline sandboxing capabilities to detect and stop suspicious QR code threats. Not only do we support behavioral and sandbox detection engines, but we also provide pre- and post-scanning for risky QR codes. When combined, these capabilities more accurately detect and better protect against this new threat vector. Most API-based email security tools rely on behavioral signals, which means they can only detect a suspicious QR code email after it has been delivered to the user\'s inbox. In contrast, Proofpoint stops attacks pre-delivery, so threats can never make it to users\' inboxes. In this blog post, we\'ll cover what you should know about QR code phishing and detection-and how Proofpoint can help. Why QR codes? When Microsoft disabled macros to prevent threat actors from exploiting them to deliver malware, threat actors started to test various new attack delivery techniques, such as QR codes. Used by marketers as a quick and easy way to connect with consumers and drive engagement, QR codes have become a part of our daily lives and are now used in retail stores, airline tickets, contactless menus and scan-to-pay, among many others. While it\'s common knowledge that standard QR codes can be used in malicious ways, a recent Scantrust QR code survey found that “over 80% of US-based QR code users said that they think QR codes are safe.” It\'s this inherent trust of QR codes that threat actors depend on. That and the fact that QR codes do not expose malicious URLs make them very hard detect with traditional email security tools. What is QR code phishing? A QR code scam is when a bad actor creates a QR code phishing campaign to trick a user into navigating to a malicious URL. This leads them to a malicious website that then harvests their credentials or downloads malware onto their device. These campaigns include payment scams, package scams, email scams and even donation scams during the holiday season. Because all QR codes look similar, users are easily fooled. Figure 1: How a QR scam typically works. Why are QR codes getting through? Legacy email security providers and most API-based email security tools have a very difficult time detecting these attacks. That\'s because these tools scan email messages for known malicious links-they don\'t scan images for links that are hidden inside QR code images. This attack method also creates a new security blind spot. QR codes are scanned by a separate device, like a smartphone, from where the email is delivered. And smartphones are less likely to have robust security protection, which is needed to detect and prevent these attacks. For this reason, it\'s essential that an email security tool detects and blocks QR code phishing emails before they reach users\' inboxes. When messages are scanned post-delivery, like with API-based tools, there\'s a chance that users will get to them first-before they\'re clawed back. Post-delivery-only detection risks Post-delivery-only email security tools claim to “detect and block” QR code phishing emails, but they simply cannot. While they may “detect” a suspicious QR code email, it\'s only after the threat has been delivered to the user\'s inbox. Moreover, these tools do not sandbox suspicious QR codes. This means they have a high miss rate-which creates more risk for your company. Besides creating more risk, they also create more work for your teams.

Defenders who want to proactively protect their company\'s identities have no shortage of security tools to choose from. There are so many, in fact, that it seems like a new category of tool is invented every few months just to help keep them all straight. Because most security teams are finding it increasingly difficult to stop attackers as they use identity vulnerabilities to escalate privilege and move laterally across their organization\'s IT environment, some of today\'s newest tools focus on this middle part of the attack chain. Endpoint detection and response (EDR) and extended detection and response (XDR) are two tools that claim to cover this specialized area of defense. But unfortunately, because of their fundamental architecture and core capabilities, that\'s not really what they do best. That\'s why a new category of tool-identity threat detection and response (ITDR)-is emerging to fill the gaps. In this blog post, we\'ll explain the difference between EDR, XDR and ITDR so that you can understand how these tools complement and reinforce each other. They each have strengths, and when they\'re combined they provide even better security coverage. But first, let\'s rewind the cybersecurity evolution timeline back to the 1980s to understand why ITDR has emerged as a critical defense measure in today\'s threat landscape. The rise of antivirus software and firewalls We\'re starting in the 1980s because that\'s the decade that saw the advent of computer networks and the proliferation of personal computers. It also saw the rapid rise of new threats due to adversaries taking advantage of both trends. There were notable computer threats prior to this decade, of course. The “Creeper” self-replicating program in 1971 and the ANIMAL Trojan in 1975 are two examples. But the pace of development picked up considerably during the 1980s as personal computing and computer networking spread, and bad actors and other mischief-makers sought to profit from or simply break into (or break) devices and systems. In 1987, the aptly named Bernd Robert Fix, a German computer security expert, developed a software program to stop a virus known as Vienna. This virus destroyed random files on the computers it infected. Fix\'s program worked-and the antivirus software industry was born. However, while early antivirus tools were useful, they could only detect and remove known viruses from infected systems. The introduction of firewalls to monitor and control network traffic is another security advancement from the decade. Early “network layer” firewalls were designed to judge “packets” (small chunks of data) based on simple information like the source, destination and connection type. If the packets passed muster, they were sent to the system requesting the data; if not, they were discarded. The internet explosion-and the escalation of cybercrime The late 1990s and early 2000s witnessed the explosive growth of the internet as a key business platform, kicking off an era of tremendous change. It brought new opportunities but also many new security risks and threats. Cybercrime expanded and became a more formalized and global industry during this time. Bad actors focused on developing malware and other threats. Email with malicious attachments and crafty social engineering strategies quickly became favorite tools for adversaries looking to distribute their innovations and employ unsuspecting users in helping to activate their criminal campaigns. As cyberthreats became more sophisticated, defenders evolved traditional detective security tools to feature: Signature-based detection to identify known malware Heuristic analysis to detect previously difficult to detect threats based on suspicious behavioral patterns All of these methods were effective to a degree. But once again, they could not keep in step with cybercriminal innovation and tended to generate a lot of false positives and false negatives.

2023-11-27 09:26:51 | 8 sujets essentiels de cybersécurité à inclure dans votre programme de formation 8 Essential Cybersecurity Topics to Include in Your Training Program (lien direct) |
Your employees have a critical role to play as a first line of defense against cyberthreats. But to be effective, they need to know what those threats are-and stay apprised of how they\'re evolving. A comprehensive security awareness program is the key to helping your users grow their understanding of attackers\' methods and objectives so they can become more proactive defenders. That includes knowing what strategies malicious actors employ to manipulate people so they can use them to enable their campaigns. The importance of security awareness It\'s well worth taking the time to craft a meaningful and engaging security awareness program. By presenting the right mix of information to your users in a compelling way, you can empower them to help you improve your organization\'s security posture as well as create a more robust security culture overall. The cybersecurity topics that you include in your program should be relevant to your business and industry, of course. Companies face different cyberthreat challenges and regulatory compliance requirements related to data protection and data privacy. That said, there are several subjects that almost any modern business, regardless of its industry, will want to ensure its employees understand. We list eight of these cybersecurity topics below. They are the go-to approaches and tools that attackers around the world commonly use to compromise users and their accounts, disrupt normal business operations, steal money or data, and do other damage. Here\'s a high-level overview of these eight must-know cybersecurity topics: 1. Social engineering Social engineering is a collection of techniques malicious actors use to manipulate human psychology. Attackers rely on these strategies to trick or threaten users to take actions such as giving up account credentials, handing over sensitive data, running malicious code and transferring funds. They do this by taking advantage of users\': Emotions, by conveying a sense of urgency, generating excitement about an opportunity, or creating fear around losing money or doing something wrong Trust, by posing as someone familiar to the user or a trusted brand or authority-such as the Internal Revenue Service (IRS), UPS, Amazon or Microsoft Fatigue, by timing attacks when users are likely to be tired or distracted and more inclined to let their “emotional mind” guide their decision-making Common social engineering tactics include phishing-which we cover in the next section-and these others: Social media reconnaissance. Attackers often turn to social media to gather information about users that they target with their campaigns. These efforts can include direct outreach to users. Vishing (voice phishing) and smishing (SMS/text phishing). Vishing is the fraudulent practice of making phone calls or leaving voice messages purporting to be from a trusted brand or authority. With smishing, attackers use text messages to send SMS messages to users or robocall them. The messages often promise gifts or services in exchange for payment. Telephone-oriented attack delivery (TOAD). TOAD attacks start with an email that claims to be from a legitimate source and includes a phone number for customer assistance. Callers are connected to fake customer service representatives who then direct the victim through the attack. They may instruct the victim to let them access their machine remotely or download a file that turns out to be malware. Or they might direct them to a phishing site. Common sense can go a long way toward preventing a social engineering attack. Make sure to reiterate that if a message seems too good to be true, it\'s very likely a scam. And if something doesn\'t look or sound right, it probably isn\'t. 2. Phishing Phishing is an example of social engineering. Most phishing messages are sent by email.

2023-11-14 05:00:49 | TA402 utilise des chaînes d'infection Ironwind complexes pour cibler les entités gouvernementales à base de Moyen-Orient TA402 Uses Complex IronWind Infection Chains to Target Middle East-Based Government Entities (lien direct) |
Points clés à retenir De juillet à octobre 2023, des chercheurs de PROVELPOINT ont observé que TA402 s'engage dans des campagnes de phishing qui ont livré un nouveau téléchargeur d'accès initial surnommé Ironwind.Le téléchargeur a été suivi par des étapes supplémentaires qui consistaient à ShellCode téléchargé. Au cours de la même période, TA402 a ajusté ses méthodes de livraison, passant de l'utilisation de liens Dropbox à l'utilisation des pièces jointes XLL et RAR, susceptibles d'échapper aux efforts de détection. Cet acteur de menace s'est toujours engagé dans une activité extrêmement ciblée, poursuivant moins de cinq organisations avec une seule campagne.Ils ont également maintenu un fort accent sur les entités gouvernementales basées au Moyen-Orient et en Afrique du Nord. Proofpoint a suivi TA402 depuis 2020. Nos chercheurs évaluent l'acteur de menace est un groupe de menace persistante avancée (APT) du Moyen-Orient qui a historiquement opéré dans l'intérêt des territoires palestiniens et chevauche des rapports publics sur MoleratS, Gaza Cybergang, Frankenstein et Wirte. Aperçu À la mi-2023, les chercheurs de la preuve ont d'abord identifié TA402 (Molerats, Gaza CyberActivité Gang, Frankenstein, Wirte) Utilisant une chaîne d'infection labyrinthique pour cibler les gouvernements du Moyen-Orient avec un nouveau point de téléchargeur d'accès initial surnommé Ironwind.De juillet à octobre 2023, TA402 a utilisé trois variations de cette infection des liens de chair de chaîne, des pièces jointes de fichiers XLL et des pièces jointes RAR-avec chaque variante conduisant constamment au téléchargement d'une DLL contenant les logiciels malveillants multifonctionnels.Dans ces campagnes, TA402 a également été éloigné de son utilisation de services cloud comme l'API Dropbox, que les chercheurs à preuves ont observés dans l'activité de 2021 et 2022, à l'utilisation d'infrastructures contrôlées par acteur pour la communication C2. Fin octobre 2023, les chercheurs de PEOTPOINT n'avaient observé aucun changement dans le ciblage par TA402, un groupe APT qui a historiquement opéré dans l'intérêt des territoires palestiniens, ni identifié aucune indication d'un mandat modifié malgré le conflit actuel dans la région.Il reste possible que cet acteur de menace redirige ses ressources à mesure que les événements continuent de se dérouler. Détails de la campagne et Ironwind Activité de juillet 2023: En juillet 2023, des chercheurs de Pointpoint ont observé le premier de la nouvelle chaîne d'infection plus compliquée de TA402 \\ par rapport à l'activité de la campagne antérieure de 2021 et 2022 (figures 1 et 2). Figure 1. Chaîne d'infection TA402 utilisée de novembre 2021 à janvier 2022. Figure 2. Chaîne d'infection TA402 utilisée dans la campagne de juillet 2023. TA402 s'est engagé dans une campagne de phishing en utilisant un compte de messagerie compromis du ministère des Affaires étrangères pour cibler les entités gouvernementales du Moyen-Orient.Les e-mails ont utilisé un leurre d'ingénierie sociale sur le thème économique ("برنامج التعاون الإقتصاDE avec les pays du Golfe Cooperation Council 2023-2024ies of the Gulf Cooperation Council 2023-2024 "]) Pour livrer un lien drobox qui a téléchargé un fichier Microsoft Powerpoint Microsoft Powerpoint (PPAM)..exe, et GathernetworkInfo.vbs. timeout.exe a été utilisé pour la localisation de Sideload Ironwind.Au moment de l'analyse en août 2023.

2023-11-13 07:23:13 | ProofPoint reconnu en 2023 Gartner & Reg;Guide du marché pour la prévention de la perte de données Proofpoint Recognized in 2023 Gartner® Market Guide for Data Loss Prevention (lien direct) |
The risk of data loss increases as your business embraces digital transformation, remote work and cloud computing. Legacy data loss prevention (DLP) solutions weren\'t developed with these new dynamics in mind. In today\'s world, your DLP platform must provide visibility across multiple channels for data loss-email, cloud services, endpoint and web. It must scale with your needs while protecting data without interruption. And since data doesn\'t lose itself, it should be people centric. Part of that means providing insight into user behavior. The Gartner Market Guide for Data Loss Prevention explains that “DLP technology is mature, but today, organizations look for comprehensive solutions that go beyond traditional DLP measures.” It also notes that “Security and risk management leaders should focus on risk-based adaptive data protection techniques to strengthen the data security of their organization.” Let\'s take a look at some other insights from the report. Adaptive DLP: Enhanced with classification and converged with insider threat management The Gartner Market Guide states that “DLP vendors are increasingly converging with insider risk management platforms. This convergence enables better detection of data exfiltration as it enriches DLP events with anomalous user behaviors, improved risk scoring and real-time monitoring capabilities.” This, the report notes, enables an adaptive, risk based DLP approach. It also shares important insights such as: Enterprise DLP (EDLP) solutions offer centralized policy management and reporting functionality Enterprise DLP (EDLP) solutions generally incorporate advanced content inspection techniques to identify complex content and apply remediation Content inspection within IDLP solutions has improved considerably, and many of these solutions can recognize classification tags from more sophisticated classification tools DLP solutions use data classification labels and tags, content inspection techniques and contextual analysis to identify sensitive content and analyze actions related to the use of that content Gartner sees that DLP vendors are increasingly converging with insider risk management platforms. This convergence enables better detection of data exfiltration as it enriches DLP events with anomalous user behaviors, improved risk scoring and real-time monitoring capabilities. Gartner recommends in its Market Guide that a business use enterprise DLP if it has limited resources and its “users are transacting sensitive information through multiple channels.” The report also mentions that consulting and managed services can help “shorten the time to value and augment lean IT and security departments.” Proofpoint delivers adaptive DLP As a key player in the space, we think Proofpoint Enterprise DLP expands on the capabilities that Gartner shares in its report. The following is an overview of how we do that. People-centric insights and risk-based adaptive DLP Proofpoint Enterprise DLP protects against data loss across email, cloud, endpoint and web. Our solution combines content, behavior and threat telemetry from all these channels to address the full spectrum of people-centric data loss scenarios such as: Leavers who feel entitled to take intellectual property with them Compromised users whose data is stolen by threat actors Careless users who accidently email sensitive documents to your partners People-centric information protection is an adaptive, risk-based approach to DLP. Our Enterprise DLP solution uses people and application risk scoring and modeling for dynamic policies. Figure 1. Web security risk-based access rule. In Figure 1, “Leavers Policy 2” applies isolation as a data control when “Risky Leavers” access “Critical Business Cloud Apps.” One console, one agent, one cloud-native platform Proofpoint provides what administrators and analysts need to accurately detect DLP and insider threats: Policy management Workflows Alert management | Tool Threat Cloud | ★ | |

ProofPoint Conformité intelligente classe le contenu texte qui provient du contenu des médias sociaux partout aux demandes fournies par le client.Une partie de notre système détecte le contenu du spam, généralement à partir de sources basées sur les médias sociaux. Un défi commun pour les systèmes de détection de spam est que les adversaires modifient leur contenu pour échapper à la détection.Nous avons un algorithme qui résout ce problème. Parfois, les faux positifs doivent également être corrigés.Nous gérons cela en maintenant une liste d'exclusion et une liste positive de signatures de spam.Dans cet article de blog, nous expliquons comment nous mettons à jour les signatures de spam en temps réel sans avoir un impact négatif sur les performances. Une nécessité d'évoluer sans compromettre les performances Au fur et à mesure que la clientèle de Proofpoint Patrol a augmenté, nous avons dû la mettre à l'échelle afin de continuer à fournir des services rapides et fiables.À l'origine, le service de catégorisation de texte était intégré à notre service de classificateur de base et n'a pas pu être mis à l'échelle indépendamment.Nous avons décidé de le séparer en son propre service afin que nous puissions le développer et l'étendre indépendamment de notre service de classificateur. Notre première libération de ce nouveau système nous a permis d'évoluer plus efficacement et a entraîné une forte diminution de la latence.Une partie de l'amélioration des performances est venue du chargement de l'ensemble de signature de spam dans la mémoire au démarrage du service. Cependant, cela a conduit à une limitation où nous ne pouvions pas facilement mettre à jour nos ensembles de signature positive ou d'exclusion sans reconstruire et redéployer notre application.Cela signifiait que notre système de spam n'apprendrait pas de nouvelles signatures de spam au fil du temps, ce qui entraînerait également une augmentation des faux négatifs. Une solution de stockage de données en mémoire: redis Peu de temps après avoir rejoint Proofpoint, j'ai été chargé d'améliorer le système de détection des spams pour apprendre au fil du temps, tout en conservant les avantages sociaux.Nous avions besoin d'une solution avec une latence à faible lecture, et idéalement une latence d'écriture faible, car notre rapport lecture / écriture était assis vers 80/20. Une solution potentielle était Redis, une solution de stockage de données en mémoire open source.Amazon propose une implémentation de Redis-MemoryDB-qui peut fournir une persistance de données au-delà de ce qu'une solution de cache typique peut offrir. Présentation d'une solution de stockage de signature en mémoire. À la fin des performances, Amazon possède une latence de lecture microseconde et une latence d'écriture à un chiffre.Tout en étudiant des solutions potentielles, nous avons remarqué des latences similaires avec notre charge de travail.

2023-11-09 14:25:13 | Comment trouver vos identités risquées How to Find Your Risky Identities (lien direct) |
Les acteurs de la menace utilisent de nombreuses techniques pour obtenir des informations d'identification de compte pour la simple raison qu'ils ouvrent la porte à une multitude de tactiques en aval. Lorsqu'ils ont des informations d'identification, les cybercriminels n'ont pas besoin de percer votre périmètre ou de rechercher des vulnérabilités existantes pour entrer. Au lieu de cela, ils peuvent s'attendre sans être détectés, se déplacer dans votre réseau, poser plusieurs charges utiles malveillantes, voler des données et ciblerAutres utilisateurs de grande valeur en cours de route.Toute défense efficace contre ce type d'attaque nécessite que vous compreniez quelle identité risquée est susceptible d'être à la réception de celle-ci. Toute identité unique peut être compromise et doit être protégée en conséquence.Cependant, certains sont plus à risque des attaques que d'autres et d'autres sont plus précieux.Lorsque vous obtenez une visibilité dans les identités les plus à risque, vous pouvez appliquer et améliorer les contrôles où ils sont le plus nécessaires. Voici un aperçu des identités sur lesquelles vous devez concentrer vos efforts ainsi que certains outils qui peuvent vous aider. 3 catégories d'identités risquées Les identités risquées peuvent être regroupées en trois catégories: Identités non gérées Les comptes de service ne sont généralement pas gérés par les outils de gestion de l'accès aux privilèges (PAM) car ils sont souvent non découverts lors de la mise en œuvre.De plus, les identités de la machine peuvent être erronées pour permettre à tort une connexion interactive par les humains. Les administrateurs locaux sont configurés pour faciliter les demandes de support informatique sur les points de terminaison et sont souvent oubliés après leur création. Les comptes privilégiés ne sont souvent pas gérés activement car ils ne sont pas constamment découverts. Identités mal configurées Les administrateurs fantômes sont généralement mal configurés en raison de la complexité des groupes d'identité imbriqués dans Active Directory.Cela peut rendre extrêmement difficile de voir les droits et les droits complets de toutes les identités.En conséquence, les administrateurs fantômes peuvent se voir accorder des privilèges excessifs involontaires. Les identités configurées avec un cryptage faible ou manquant et celles qui n'appliquent pas de mots de passe solides entrent également dans cette catégorie. Identités exposées Les informations d'identification en cache sont généralement stockées sur les points de terminaison, les navigateurs, la mémoire, le registre et le disque.En conséquence, ils peuvent être facilement exploités à l'aide d'outils d'attaquant communs. Les jetons d'accès cloud stockés sur les points de terminaison sont également un moyen courant pour les attaquants d'accéder aux actifs cloud. Les séances d'application à distance, telles que RDP, peuvent être mal fermées.Si cela se produit, les cybercriminels peuvent les utiliser pour compromettre une session ouverte et ses privilèges, sans risque de détection. Ces identités sont risquées. C'est là que vivent des identités risquées. Défense de la menace d'identité de la preuve Plus de 90% des attaques reposent sur des identités compromises.C'est pourquoi vous avez besoin de la défense de la menace d'identité de la preuve.ProofPoint peut vous aider à détecter les menaces actives et à éliminer les lacunes de votre posture d'identité qui peuvent être exploitées par les attaquants.

2023-11-09 07:02:10 | Le pouvoir de la simplicité: élever votre expérience de sécurité The Power of Simplicity: Elevating Your Security Experience (lien direct) |
Recent research underscores just how challenging the current threat and risk landscape is for businesses and their security and IT teams. Ransomware attacks are up 153% year over year. Business email compromise (BEC) attacks doubled during the same period. Meanwhile, the global deficit of skilled security personnel sits at about 4 million. New threats are emerging and existing ones are growing more sophisticated all the time. Security measures need to keep pace with these dynamics to be effective. Businesses must be proactive and aim to stop threats before they start, but still be able to respond with speed to incidents already in progress. To do that, you must understand how attackers are targeting your business. And you must be able to clearly communicate those risks to executive leadership and peer stakeholders. At Proofpoint, our goal is to protect our customers from advanced threats by streamlining our solutions and processes while also providing easy-to-understand threat visibility. That\'s why we introduced improvements to the usability and reporting of the Proofpoint Aegis threat protection platform. Read on to learn more. 3 Aegis usability enhancements The market spoke, and we listened. Feedback from our customers was key in developing all of the following user interface (UI) enhancements, which we focused around three goals: simplifying access, prioritizing usability and clarifying the threat landscape. 1: Simplifying access Complexity hinders productivity and innovation. With that in mind, Proofpoint launched a new single sign-on (SSO) portal to provide a centralized, frictionless user login experience to Aegis. Customers can now use a single URL and single set of credentials to log in to the platform and switch seamlessly between our products. That\'s a big win for businesses that use multiple Proofpoint solutions. Your business can expect to see improved operational efficiency. By simplifying access to the Aegis platform, we\'re reducing the time admins spend getting to work, navigating their environments and searching for tools. The SSO portal is a significant step forward in improving the usability and user experience of the Proofpoint Aegis platform. 2: Prioritizing usability Proofpoint\'s user-centric design approach means our solutions are becoming more intuitive and easier to use all the time. The new usability updates for Aegis reduce cognitive load by minimizing the mental effort that\'s required to focus on processes. This makes creating natural workflows less complex, which results in fewer errors and less time spent on manual work. Our intuitively designed tools reduce frustration and effort for users by enabling faster onboarding. They also provide better problem-solving and self-troubleshooting capabilities. Our goal of improved usability led us to incorporate new Email Protection modules into the updated cloud administration portal. The modules offer streamlined workflows and quicker response times. This means admins can perform their daily tasks and manage email threats more easily. And they don\'t have to navigate through complicated menus. The Email Protection modules are available now in PPS 8.20; they include the Email Firewall and Spam Configuration UIs. 3: Clarifying the threat landscape Proofpoint has long been at the forefront of bringing clarity to the threat landscape. And we know that when security and IT teams have more visibility, they can make more informed decisions. However, we also know that for actionable decisions to be truly effective, threat landscape visibility needs to be quick and easy for other stakeholders to grasp as well. We\'re striving to minimize information overload through summarized and contextually driven documentation. This helps you to always know and understand the cyberthreats your business is facing. Clear, easy to access data allows administrators to move fast to keep up with evolving threats. It also enhances the ability to communicate risk to nontechnical stakeholders w | Ransomware Spam Tool Threat Cloud | ★★ | |

2023-11-08 06:00:00 | Protéger vos chemins, partie 1: comment la gestion du chemin d'attaque peut arrêter les attaquants sur leurs traces Protecting Your Paths, Part 1: How Attack Path Management Can Stop Attackers in Their Tracks (lien direct) |
This blog is the first in a series where we explore attack path management. We\'ll explain what you need to know and give you the tools you need to help you better protect the middle of the attack chain. A big reason that successful cyberattacks are on the rise is that threat actors are shifting their tactics to identity-based attacks. Last year, 84% of businesses fell victim to an identity-related breach. When attackers land on a host, it is rarely their end target. Instead, they look to escalate privilege and move laterally across an environment. Their next step is to exploit more privileged credentials, and they often do this by using shadow admin vulnerabilities. It can be a challenge to stop them. To do so, you need to quickly discover, prioritize and remediate identity vulnerabilities. But first, you need to know what you\'re up against. In this blog post, we explore the multitude of identity vulnerability challenges, and we explain why an attack path management (APM) view is so important. We also specify which identity-centric attack vectors are likely to exist in your environment. Key terms Before we dive into this topic further, let\'s define some key terms that are central to this area of security: Attack path management. This refers to the process of identifying, analyzing, understanding and remediating attack paths within a business. Identities and other system resources are typically spread across multiple on-premises and cloud identity stores. These include Microsoft Active Directory (AD), Entra ID (formerly Azure AD), AWS and Okta. Attack path. Threat actors follow a sequence of steps as they compromise security, which is called an attack path. The typical end result is the compromise of a tier-zero asset (TZA)-or what is generally referred to as a bad breach. TZAs. Tier-zero assets are often referred to as the “crown jewels.” They are a company\'s most critical and sensitive assets. They can include systems, data or other resources (databases, web gateways) that are essential to its operation, reputation and overall resilience. In certain scenarios, AD domain controllers or authentication systems can be considered TZAs given the broad scope of damage that can arise with their breach. The risks of TZA compromise Compromising a tier-zero asset is a high-value objective for attackers because it allows them to achieve their financial or other malicious goals. Here are some common objectives: Data exfiltration TZAs may store or have access to critical and sensitive data or intellectual property. Or they might be critical system resources that, if compromised, could result in a service outage. Attackers aim to steal this information for financial gain, espionage or extortion. Data exfiltration clearly impacts the confidentiality part of the CIA triad. Data manipulation Attackers may alter or manipulate data within TZAs to achieve their goals. For instance, they could modify user account settings, insert malicious code or encrypt data as a step toward operational disruption. Data manipulation impacts the integrity part of the CIA triad. Denial of service (DoS) or disruption Attackers may use compromised tier-zero assets to launch DoS attacks against critical operational services in an enterprise. This can disrupt services and cause operational or financial harm to the business. This exposure category is about impacting the availability portion of the CIA triad. Ransomware Attackers may use their control over TZAs to deploy ransomware across a network. By encrypting critical systems and data, they can demand substantial ransom payments in exchange for the decryption keys. Ultimately ransomware attackers are focused on financial gain. One of their main tactics for extracting a ransom is threatening to directly impact system availability. (See this 2021 breach as an example.) Lateral movement to more TZAs Once attackers compromise a tier-zero asset, they can use it as a launch pad to move laterally to other TZAs. Figure 1.

2023-10-26 06:00:18 | Break the Attack Chain with Identity Threat Protection (lien direct) | “The attacker only has to be right once. Defenders have to get it right every time.” This well-known saying has shaped countless cybersecurity strategies. The belief is that a single compromise of our defenses can lead to a catastrophic outcome. As new risks emerge and attackers develop tactics to evade controls, defenders face the daunting task of protecting an ever-expanding array of connected identities. Many companies now embrace resilience strategies, accepting that an incident is inevitable - “It\'s not a matter of if, but when.” That\'s because defenders have been fixated on the impossible task of protecting everything within the business. But a new industry approach to cyber defense in recent years has emerged that points the path towards a better way. Instead of protecting everything, defenders should aim to neutralize attackers\' tactics, techniques and procedures (TTPs), which are hard to replace. This disrupts the completion of the attack chain. What is the attack chain? And how does identity threat protection disrupt it? That\'s what we\'re here to discuss. The enduring relevance of the attack chain No other concept has captured the essence of successful cyber attacks like the attack chain (aka the “cyber kill chain”), which was developed by Lockheed Martin in 2011. Even 12 years later, the attack chain remains relevant, while defenders struggle to prevent the most impactful incidents. While cyber criminals don\'t follow the same steps every time, the basic phases of an attack are pretty much always the same: Steps in the cyber attack chain. The challenge of initial compromise The first phase in the attack chain is the initial compromise. Modern cyber criminals use an array of tactics to infiltrate companies and wreak havoc on their systems, from BEC attacks to cloud account takeovers and ransomware incidents. One trend is to exploit trusted third-party relationships to compromise companies through their suppliers. What seems like an innocuous initial email can escalate into a full-scale compromise with great speed. Once attackers gain unrestricted access to a company\'s domain, they can infiltrate email accounts to commit fraudulent activities. One alarming twist to credential phishing emails is that they can evade detection. They leave behind no traces of compromise or malware. Even with the rise of multifactor authentication (MFA), these attacks continue to surge. Once accounts are compromised through a credential phishing email or a vulnerable remote desktop session, businesses face the next phase of the attack chain: privileged escalation and lateral movement within their networks. Next phase: privilege escalation and lateral movement This is the middle of the attack chain. And it\'s where threat actors try to breach a company\'s defenses. Often, they do this by compromising the identities of employees, contractors, service providers or edge devices. Their main goal is to use this initial access to elevate their privileges, typically targeting Active Directory (AD). AD, which many businesses around the world use, is susceptible to compromise. It can provide attackers with unparalleled control over a company\'s computing infrastructure. With this access, they can engage in lateral movement and spread malware across the business, causing more harm. Finally, the risk of data loss Attackers don\'t rely on a single stroke of luck. Their success hinges on a series of precise maneuvers. Monetary gains through data exfiltration are often their objective. And once they have navigated the intricate web of identities, they can target valuable data and orchestrate data theft operations. Defenders must disrupt this chain of events to prevent the loss of sensitive data, like intellectual property or customer identifiable data. Then, they can gain the upper hand and steer the course of cybersecurity in their favor. The three best opportunities to break the attack chain.

Un exécuteur de tâches distribué est un composant crucial lorsque vous créez des systèmes évolutifs et résilients qui peuvent gérer une large gamme de tâches, du traitement des données et des travaux de lots au traitement d'événements en temps réel et à l'orchestration des microservices. Chez ProofPoint, nous recherchions un exécuteur de tâches distribué simple pour le sous-ensemble des tâches à exécuter dans AWS.Nous voulions qu'il soit facile à entretenir et à déployer, à fournir une commande cohérente des tâches, à avoir une bonne gestion des erreurs et à réessayer les tâches ratées.L'intégration avec des composants sans serveur était un plus car il nous fournirait beaucoup plus d'options pour augmenter et paralléliser le traitement des tâches. Parmi les nombreux cadres que nous avons évalués les plus notables figuraient Hazelcast, Apache Air Flow et Facebook Bistro.Apache Air Flow et Bistro ont besoin d'un déploiement d'infrastructures supplémentaires, tandis que Hazelcast a besoin de persistance pour être configurée pour stocker l'état de la tâche.Nous voulions limiter les dépendances autres que ce que nous utilisons déjà dans AWS.En fin de compte, nous avons décidé qu'AWS SQS était le meilleur de toutes les options. En utilisant les fonctionnalités des files d'attente AWS SQS, nous avons pu assembler un planificateur de tâches distribué et un cadre d'exécution comme indiqué ci-dessous dans la figure 1. Figure 1: La file d'attente FIFO AWS SQS en tant qu'orchestrateur entre la source de tâche et les exécuteurs. Caractéristiques de conception clés de l'architecture ci-dessus Le plan de l'architecture ci-dessus est partagé en tant que module Terraform afin que chaque équipe ou service puisse déployer son propre planificateur de tâches distribué hautement disponible.Voici ce que vous devez savoir sur ses caractéristiques de conception clés: Fonctionnalité Description Disponibilité Un aspect clé de tout exécuteur de tâches distribué est d'éliminer le point de défaillance unique.Étant donné que AWS SQS est résilient et très disponible, cela signifie que la file d'attente des tâches l'est aussi. Évolutivité SQS propose l'intégration hors de la boîte avec AWS LAMDA à l'aide de la LAMDA Invocation via des déclencheurs de source d'événements.

2023-10-23 05:00:00 | De Copacabana à Barcelone: la menace croisée des logiciels malveillants brésiliens brésiliens From Copacabana to Barcelona: The Cross-Continental Threat of Brazilian Banking Malware (lien direct) |
Key Takeaways A new version of Grandoreiro malware from TA2725 targets both Mexico and Spain. Previously this malware has only targeted victims in Brazil and Mexico. Overview Proofpoint researchers have long tracked clusters of malicious activity using banking malware to target users and organizations in Brazil and surrounding countries. Recently, researchers observed multiple threat clusters targeting Spain from threat actors and malware that have traditionally targeted Portuguese and Spanish speakers in Brazil, Mexico, and other parts of the Americas. While the targeting of victims in the Americas has been common for some time, recent clusters targeting Spain have been unusual in frequency and volume compared to previous activity. Brazilian Cyber Threat Landscape The Brazilian cyber threat landscape has changed rapidly over the last several years becoming more complicated and diverse. More people than ever are online in the country meaning the potential victim base has increased. According to third-party reporting, Brazil is among the most highly-targeted countries for information stealers and other malware, and its broad adoption of online banking offers potential for threat actors to social engineer people eager to conduct financial activity online. Brazilian Banking Malware Brazilian banking malware comes in many varieties, but, based on Proofpoint observations, most of them appear to have a common ancestor written in Delphi with source code reused and modified over many years. This base malware has spawned many varieties of Brazilian malware including Javali, Casabeniero, Mekotio, and Grandoreiro. Some malware strains like Grandoreiro are still in active development (both the loader and the final payload). Grandoreiro has capabilities to both steal data through keyloggers and screen-grabbers as well as steal bank login information from overlays when an infected victim visits pre-determined banking sites targeted by the threat actors. Based on recent Proofpoint telemetry, Grandoreiro is typically delivered with an attack chain beginning with a URL in an email with various lures including shared documents, Nota Fiscal Electronicos (NF-e, a tax form required to be used by organizations in Brazil), and utility bills. Once a victim clicks the URL, they are delivered a zip file containing the loader, usually an MSI, HTA or exe file. If the user runs the loader, the malicious file will use DLL injection to add malicious behavior to an otherwise legitimate but vulnerable program included in the zip file with the loader. The loader will then download and run the final Grandoreiro payload and check in with a command and control (C2) server. Previously, bank customers targeted by Grandoreiro overlays have been in Brazil and Mexico, but recent Grandoreiro campaigns show that this capability has been expanded to banks in Spain as well. Two campaigns attributed to TA2725 spanning from 24 through 29 August 2023 shared common infrastructure and payload while targeting both Mexico and Spain simultaneously. This development means that the Grandoreiro bank credential stealing overlays now include banks in both Spain and Mexico in the same version so that the threat actors can target victims in multiple geographic regions without modification of the malware. Figure 1. Common C2 and payload download for both campaigns. Threat actors from the Americas have previously targeted organizations in Spain but have typically used more generic malware or phishing campaigns that were unique to Spain. In this case, the threat actors have expanded this version of Grandoreiro that had previously only targeted the Americas to include other parts of the world. Figure 2. Example of TA2725 targeting of victims in Spain in August and September by spoofing ÉSECÈ Group, a Spanish manufacturing company. Figure 3.

2023-10-16 07:29:59 | Navigation du cyber-risque: ce qu'il faut rechercher dans la couverture de la cyber-assurance Navigating Cyber Risk: What to Look for in Cyber Insurance Coverage (lien direct) |
Modern threats like phishing, ransomware and data breaches cast a dark cloud over businesses across sectors. For most bad actors, the goal of an attack is financial. As Proofpoint noted in the 2023 State of the Phish report, 30% of businesses that endured a successful attack experienced a direct monetary loss, such as a fraudulent invoice, wire transfer or payroll redirection. That is an increase of 76% year over year. A cyber insurance policy can protect you from the financial losses caused by cybersecurity incidents and data breaches. And when businesses pair cyber insurance with the prowess of Proofpoint solutions, they can build a formidable defense strategy. In this blog, we\'ll go over some best practices for choosing and managing you cyber insurance policy so you can protect yourself from risk. Actions that cyber criminals monetize Our research for the latest State of the Phish report shows that the three most common consequences of a cyber attack are: Data breach (44%) Ransomware infection (43%) Account compromise (36%) Notably, cyber criminals can monetize all these actions. Most common results of successful phishing attacks. (Source: 2023 State of the Phish report from Proofpoint.) Just one cybersecurity incident can cost tens of thousands of dollars. So, it\'s easy to understand why insurers see these incidents as too costly to cover in their general liability policies. But with cyber insurance, your business has a tool to help manage risk. Why cyber insurance can be a vital financial safety net While firewalls and endpoint protections remain vital, the truth is that a level of residual risk always exists. No matter how fortified your security is, breaches can happen due to ingenious adversaries, human error or just unfortunate circumstances. This is where cyber insurance comes to the rescue. It is the safety net that catches your business when your defenses fall short. It can help you cover costs like ransomware payments, legal fees, and costs associated with crisis management and revenue loss. In the graphic below, we can see how often cyber insurance covered losses from ransomware attacks among those surveyed for our 2023 State of the Phish report. Nearly three-quarters (73%) of businesses with cyber insurance policies said their insurers paid at least some of their ransomware-related losses. (Source: 2023 State of the Phish report from Proofpoint.) Cyber insurance best practices Now that we\'ve covered why cyber insurance can be a vital financial safety net, let\'s look at some essential best practices for cyber insurance. These measures can help your business become more effective at managing cybersecurity risks. Find an expert and ask for support and guidance. Specialized brokers are your allies in the intricate world of cyber insurance. Insurers vary in risk appetite, claim acceptance rates and expertise. Brokers have an in-depth grasp of this landscape, and they will assess your options meticulously. They will help ensure that the policy you choose is the right fit for your industry, size, risk profile and more. Be prepared for a rigorous assessment. Today, insurers want more insight into your company\'s security protocols and controls before they issue a cyber insurance policy. So preparedness is key. Be ready to provide evidence, like external audits, penetration test results and compliance certifications to insurers. If you implement access controls that insurers deem vital, such as multifactor authentication (MFA) and privileged access management (PAM), it may help to reduce your premiums. Closely examine coverage scope. Coverage specifics vary globally. But you will find that most cyber insurance policies cover a portion of losses from ransomware attacks and expenses linked to crisis responses. You need to have a thorough understanding of the breach scenarios your policy does or does not cover. Take note of any exclusions. Also, be sure to scrutinize services like breach investigation support, legal | Ransomware Tool Threat Guideline Cloud | ★★★ | |

2023-10-10 17:00:00 | Le nouveau rapport Ponemon montre que les organisations de soins de santé font peu de progrès dans la protection des patients contre les dommages des cyberattaques New Ponemon Report Shows Healthcare Organizations Are Making Little Progress in Protecting Patients from the Harms of Cyber Attacks (lien direct) |
The healthcare sector is finally acknowledging that cyber attacks affect more than just the financial bottom line. Providers are starting to understand that a weak cybersecurity posture puts patients\' safety and well-being at risk-and may endanger lives. Despite this growing understanding, however, little progress has been made in the past year to improve organizational security. The Ponemon Institute\'s second annual Cyber Insecurity in Healthcare: The Cost and Impact on Patient Safety and Care 2023 report, commissioned by Proofpoint, shows that healthcare businesses have made no strides in protecting patients from the physical harm of cyber attacks. The survey found that 88% of healthcare companies experienced an average of 40 attacks in the past 12 months. Among the 653 healthcare and IT security practitioners surveyed: 66% said cyber attacks targeting their business disrupted patient care 50% experienced an increase in complications from medical procedures 23% saw an increase in mortality rates These numbers are similar to last year\'s report and confirm what\'s already well-known in the industry: Change is slow in healthcare, especially when it comes to IT investments. The devastating impacts of various attacks on patient safety The most common types of attacks examined in the Ponemon report are: Cloud compromise Ransomware Supply chain Business email compromise (BEC) We learned that supply chain attacks are the most likely to disrupt patient care (77%, up from 70% in 2022). However, when it comes to specific repercussions, BEC leads in three of five categories. This is the type of attack most likely to cause poor outcomes due to: Delays in tests and procedures (71%) An increase in complications from medical procedures (56%) A longer length of stay (55%) What may surprise healthcare leaders and clinicians is the impact of data loss or exfiltration. When protected health information (PHI) is compromised, most think in terms of the impact to patient privacy. However, the report shows that the implications are far more dangerous. Forty-three percent of survey participants said a data loss or exfiltration incident affected patient care. Of those that experienced this impact, 46% saw an increase in mortality rates, and 38% noted an increase in medical procedure complications. Cloud risk on the rise as adoption grows The healthcare sector has lagged behind most other industries in cloud adoption. It took a global pandemic to shake things up: Sixty-two percent of surveyed physicians said the pandemic forced them to make upgrades to technology that would have taken years to accomplish otherwise. But with the broad adoption of cloud apps, care providers are more vulnerable to cloud threats. ECRI (an independent authority on healthcare technology and safety) ranked care disruption due to the failure to manage cyber risk of cloud-based clinical systems as one of the top 10 healthcare technology hazards for 2023. Given the high rate of adoption, it\'s not surprising the Ponemon report found that cloud compromise is now the top concern for healthcare companies. Cloud compromise rose to first place this year from fifth last year-with 63% of respondents expressing this concern, compared with 57% in 2022. Likewise, healthcare businesses are feeling the most vulnerable to a cloud compromise than other types of attacks, with 74% of respondents in agreement. Ransomware remains ever-present, despite decreased concerns One surprising finding from the survey is the significant decrease in concerns about ransomware attacks. Although 54% of respondents reported that their business had experienced a ransomware attack (up from 41% in 2022), they\'re the least worried about this type of threat. Only 48% of those surveyed said ransomware was a concern-a big decline from last year\'s 60%. Based on recent events, we know that the impacts of ransomware incidents are getting worse.

2023-10-04 06:00:00 | Arrêt de cybersécurité du mois & # 8211;Phishing du code QR Cybersecurity Stop of the Month – QR Code Phishing (lien direct) |
This blog post is part of a monthly series exploring the ever-evolving tactics of today\'s cyber criminals. Cybersecurity Stop of the Month focuses on the critical first steps in the attack chain-reconnaissance and initial compromise-in the context of email threats. The series is designed to help you understand how to fortify your defenses to protect people and defend data against emerging threats in today\'s dynamic threat landscape. The first two steps of the attack chain: reconnaissance and initial compromise. In our past installments, we have covered supplier compromise, EvilProxy, SocGholish and e-signature phishing. All of these are examples of threats we regularly detect for our customers before they\'re delivered to users. In this post, we explore a recent detection of a phishing attack in which the URL was encoded into a QR code. We\'ll also explore the mechanisms employed by our AI-driven detection stack that ultimately prevented the email from reaching the inbox of its intended target. The scenario Phishing, especially credential phishing, is today\'s top threat. Bad actors constantly devise new methods and tools to gain authenticated access to users\' accounts. This illicit entry often results in financial loss, data breaches and supplier account compromise that leads to further attacks. We recently detected a phishing attack hidden behind a QR code at an agriculture company with more than 16,000 employees. Fortunately, our Aegis platform detected the threats and broke the attack chain. In this scenario, a bad actor crafted a phishing lure purporting to contain completed documentation about the target\'s wages. Instead of including a link for the target to click, the bad actor included a QR code instructing the recipient to scan with their mobile phone\'s camera to review the documentation. Once scanned, a fake SharePoint login screen prompts the user to provide credentials. QR Code phishing represents a new and challenging threat. It moves the attack channel from the protected email environment to the user\'s mobile device, which is often less secure. With QR codes, the URL isn\'t exposed within the body of the email. This approach renders most email security scans ineffective. What\'s more, decoding QR codes using image recognition or optical character recognition (OCR) quickly becomes resource intensive and difficult to scale. The Threat: How did the attack happen? Here is a closer look at how the recent attack unfolded: 1. The deceptive message: An email claiming to contain employee payroll information sent from the organization\'s human resources department. Malicious email blocked by Proofpoint before it was delivered to the user\'s mailbox. (Note: For safety, we replaced the malicious QR code with one linking to Proofpoint.com. The rest of the message is a redacted screenshot of the original.) 2. QR Code Attack Sequence: The recipient is instructed to scan the QR code with their mobile device. Typical QR Code Attack Sequence for Phishing. 3. SharePoint phishing lure: Once the user decodes the URL, a fake SharePoint login screen tries to fool the recipient into entering credentials. Decoded QR code redirecting to an example SharePoint phishing page. Detection: How did Proofpoint detect the attack? QR Code phishing threats are challenging to detect. First, the phishing URL isn\'t easy to extract and scan from the QR code. And most benign email signatures contain logos, links to social media outlets embedded within images and even QR codes pointing to legitimate websites. So the presence of a QR code by itself isn\'t a sure sign of phishing . We employ an advanced blend of signals and layers of analysis to distinguish between weaponized and benign QR codes. We analyze and profile: The sender The sender\'s patterns The relationship of the sender and recipient based on past communication Those clues help identify suspicious senders and whether they are acting in a way that deviates from an established | Tool Threat Cloud | ★★ |
