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.

2024-05-06 07:54:03 | Genai alimente la dernière vague des menaces de messagerie modernes GenAI Is Powering the Latest Surge in Modern Email Threats (lien direct) |
Generative artificial intelligence (GenAI) tools like ChatGPT have extensive business value. They can write content, clean up context, mimic writing styles and tone, and more. But what if bad actors abuse these capabilities to create highly convincing, targeted and automated phishing messages at scale? No need to wonder as it\'s already happening. Not long after the launch of ChatGPT, business email compromise (BEC) attacks, which are language-based, increased across the globe. According to the 2024 State of the Phish report from Proofpoint, BEC emails are now more personalized and convincing in multiple countries. In Japan, there was a 35% increase year-over-year for BEC attacks. Meanwhile, in Korea they jumped 31% and in the UAE 29%. It turns out that GenAI boosts productivity for cybercriminals, too. Bad actors are always on the lookout for low-effort, high-return modes of attack. And GenAI checks those boxes. Its speed and scalability enhance social engineering, making it faster and easier for attackers to mine large datasets of actionable data. As malicious email threats increase in sophistication and frequency, Proofpoint is innovating to stop these attacks before they reach users\' inboxes. In this blog, we\'ll take a closer look at GenAI email threats and how Proofpoint semantic analysis can help you stop them. Why GenAI email threats are so dangerous Verizon\'s 2023 Data Breach Investigations Report notes that three-quarters of data breaches (74%) involve the human element. If you were to analyze the root causes behind online scams, ransomware attacks, credential theft, MFA bypass, and other malicious activities, that number would probably be a lot higher. Cybercriminals also cost organizations over $50 billion in total losses between October 2013 and December 2022 using BEC scams. That represents only a tiny fraction of the social engineering fraud that\'s happening. Email is the number one threat vector, and these findings underscore why. Attackers find great success in using email to target people. As they expand their use of GenAI to power the next generation of email threats, they will no doubt become even better at it. We\'re all used to seeing suspicious messages that have obvious red flags like spelling errors, grammatical mistakes and generic salutations. But with GenAI, the game has changed. Bad actors can ask GenAI to write grammatically perfect messages that mimic someone\'s writing style-and do it in multiple languages. That\'s why businesses around the globe now see credible malicious email threats coming at their users on a massive scale. How can these threats be stopped? It all comes down to understanding a message\'s intent. Stop threats before they\'re delivered with semantic analysis Proofpoint has the industry\'s first predelivery threat detection engine that uses semantic analysis to understand message intent. Semantic analysis is a process that is used to understand the meaning of words, phrases and sentences within a given context. It aims to extract the underlying meaning and intent from text data. Proofpoint semantic analysis is powered by a large language model (LLM) engine to stop advanced email threats before they\'re delivered to users\' inboxes in both Microsoft 365 and Google Workspace. It doesn\'t matter what words are used or what language the email is written in. And the weaponized payload that\'s included in the email (e.g., URL, QR code, attached file or something else) doesn\'t matter, either. With Proofpoint semantic analysis, our threat detection engines can understand what a message means and what attackers are trying to achieve. An overview of how Proofpoint uses semantic analysis. How it works Proofpoint Threat Protection now includes semantic analysis as an extra layer of threat detection. Emails must pass through an ML-based threat detection engine, which analyzes them at a deeper level. And it does | Ransomware Data Breach Tool Vulnerability Threat | ChatGPT | ★★★ |

2024-05-06 05:52:32 | La sécurité des e-mails est désormais redéfinie avec des capacités de protection des menaces adaptatives dans toute la chaîne de livraison Email Security is Now Redefined with Adaptive Threat Protection Capabilities Across the Entire Delivery Chain (lien direct) |
Another RSA Conference has arrived, and with it comes the gold standard report for our industry, the Verizon DBIR. And for yet another year, it concludes the same thing: the human element is central to the vast majority of breaches (76% this year), especially the ones that matter, from ransomware to BEC to data loss. The very first word of the 2024 DBIR is also not new; it\'s “phishing”. Email security has always been central to human risk: it\'s the #1 way users encounter threats, the #1 way users make mistakes, and the #1 way attackers get what they want, from credentials to wire transfers to malware infections. Proofpoint has a long history of stopping more human-targeted threats than anyone else. Our long history of firsts includes the first ML models to stop unwanted messages, the first rewriting of URLs for click-time protection, and the first connection of a malware sandbox to email. But attackers have continued to innovate and so have we – starting now, we\'re setting a new standard for protection across the entire email delivery chain. Building an Unmatched Detection Ensemble What organizations need in email security is simple to describe but hard to do: a single solution to protect against every type of threat, every time, every way a user may encounter it, using every form of detection. Our detection ensemble was already the industry\'s most effective, including threat intelligence, static analysis, sandboxing, click-time protection, and our unique set of Nexus AI models. I\'m thrilled to announce that we have now added the industry\'s first ever pre-delivery protections to stop social engineering and malicious URLs, as well as our newly integrated post-delivery behavioral AI, Proofpoint Adaptive Email Security. * New capability According to our data across more than 500,000 organizations, including 87 of the Fortune 100, attackers rely on two techniques more frequently than any others: text-based social engineering and malicious URLs. While we already detect both these threat types at the highest rates in the industry, we wanted to push the envelope – not just detecting them, but detecting them as early as possible. To make this a reality, we optimized the performance of our Nexus AI LLM-based detection model by 10X, enabling us to use semantic analysis to interpret a malicious message\'s intent (such as invoicing fraud), regardless of the words they use or even the language they write in. In parallel, we built the capability for our gateway to hold messages with suspicious URLs until they are sandboxed. The result is the most formidable set of defense in-depth measures available for organizations to prevent attacks from reaching their targets. Continuous End-to-End Detection with Proofpoint Adaptive Email Security Joining our pre-delivery enhancements is Proofpoint Adaptive Email Security, our API-based offering that integrates with Microsoft 365 and applies our broad detection ensemble to stop advanced threats, including BEC, social engineering and lateral phishing messages. Once deployed, Adaptive Email Security enriches all detections with easy-to-understand explanations about behavioral anomalies observed. Additionally, it automatically quarantines high confidence threats, while delivering real-time coaching using contextual warning banners to alert users to the risks in social engineering and BEC-type emails that don\'t contain an obvious malicious payload. Insight into a malicious message generated by Adaptive Email Security The Next Level While we\'re thrilled for you all to experience our latest set of innovations, we know we can still do more to help you protect your people. That takes two main forms: continuing to lead with Nexus AI, and deepening and strengthening our ecosystem partnerships.

2024-04-11 06:23:43 | FAQS de l'état de l'État 2024 du rapport Phish, partie 1: Le paysage des menaces FAQs from the 2024 State of the Phish Report, Part 1: The Threat Landscape (lien direct) |
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? What are security best practices to help defend against these novel phishing attacks?

2024-04-05 06:00:25 | Amélioration de la détection et de la réponse: plaider en matière de tromperies Improving Detection and Response: Making the Case for Deceptions (lien direct) |
Let\'s face it, most enterprises find it incredibly difficult to detect and remove attackers once they\'ve taken over user credentials, exploited hosts or both. In the meantime, attackers are working on their next moves. That means data gets stolen and ransomware gets deployed all too often. And attackers have ample time to accomplish their goals. In July 2023, the reported median dwell time was eight days. That\'s the time between when an attacker accesses their victim\'s systems and when the attack is either detected or executed. Combine that data point with another one-that attackers take only 16 hours to reach Active Directory once they have landed-and the takeaway is that threats go undetected for an average of seven days. That\'s more than enough time for a minor security incident to turn into a major business-impacting breach. How can you find and stop attackers more quickly? The answer lies in your approach. Let\'s take a closer look at how security teams typically try to detect attackers. Then, we can better understand why deceptions can work better. What is the problem with current detection methods? Organizations and their security vendors have evolved when it comes to techniques for detecting active threats. In general, detection tools have focused on two approaches-finding files or network traffic that are “known-bad” and detecting suspicious or risky activity or behavior. Often called signature-based detection, finding “known-bad” is a broadly used tool in the detection toolbox. It includes finding known-bad files like malware, or detecting traffic from known-bad IPs or domains. It makes you think of the good old days of antivirus software running on endpoints, and about the different types of network monitoring or web filtering systems that are commonplace today. The advantage of this approach is that it\'s relatively inexpensive to build, buy, deploy and manage. The major disadvantage is that it isn\'t very effective against increasingly sophisticated threat actors who have an unending supply of techniques to get around them. Keeping up with what is known-bad-while important and helpful-is also a bit like a dog chasing its tail, given the infinite internet and the ingenuity of malicious actors. The rise of behavior-based detection About 20 years ago, behavioral-based detections emerged in response to the need for better detection. Without going into detail, these probabilistic or risk-based detection techniques found their way into endpoint and network-based security systems as well as SIEM, email, user and entity behavior analytics (UEBA), and other security systems. The upside of this approach is that it\'s much more nuanced. Plus, it can find malicious actors that signature-based systems miss. The downside is that, by definition, it can generate a lot of false positives and false negatives, depending on how it\'s tuned. Also, the high cost to build and operate behavior-based systems-considering the cost of data integration, collection, tuning, storage and computing-means that this approach is out of reach for many organizations. This discussion is not intended to discount the present and future benefits of newer analytic techniques such as artificial intelligence and machine learning. I believe that continued investments in behavior-based detections can pay off with the continued growth of security data, analytics and computing power. However, I also believe we should more seriously consider a third and less-tried technique for detection. Re-thinking detection Is it time to expand our view of detection techniques? That\'s the fundamental question. But multiple related questions are also essential: Should we be thinking differently about what\'s the best way to actively detect threats? Is there a higher-fidelity way to detect attackers that is cost-effective and easy to deploy and manage? Is there another less-tried approach for detecting threat actors-beyond signature-based and behavior-based methods-that can dra | Ransomware Malware Tool Vulnerability Threat | ★★ | |

2024-04-04 11:47:34 | Latrodectus: ces octets d'araignée comme la glace Latrodectus: This Spider Bytes Like Ice (lien direct) |
Proofpoint\'s Threat Research team joined up with the Team Cymru S2 Threat Research team, in a collaborative effort to provide the information security community with a comprehensive view of the threat activity described. Key takeaways Proofpoint first observed new malware named Latrodectus appear in email threat campaigns in late November 2023. While use of Latrodectus decreased in December 2023 through January 2024, Latrodectus use increased in campaigns throughout February and March 2024. It was first observed in Proofpoint data being distributed by threat actor TA577 but has been used by at least one other threat actor, TA578. Latrodectus is an up-and-coming downloader with various sandbox evasion functionality. While similar to IcedID, Proofpoint researchers can confirm it is an entirely new malware, likely created by the IcedID developers. Latrodectus shares infrastructure overlap with historic IcedID operations. While investigating Latrodectus, researchers identified new, unique patterns in campaign IDs designating threat actor use in previous IcedID campaigns. Overview Proofpoint identified a new loader called Latrodectus in November 2023. Researchers have identified nearly a dozen campaigns delivering Latrodectus, beginning in February 2024. The malware is used by actors assessed to be initial access brokers (IABs). Latrodectus is a downloader with the objective of downloading payloads and executing arbitrary commands. While initial analysis suggested Latrodectus was a new variant of IcedID, subsequent analysis confirmed it was a new malware most likely named Latrodectus, based on a string identified in the code. Based on characteristics in the disassembled sample and functionality of the malware, researchers assess the malware was likely written by the same developers as IcedID. This malware was first observed being distributed by TA577, an IAB known as a prolific Qbot distributor prior to the malware\'s disruption in 2023. TA577 used Latrodectus in at least three campaigns in November 2023 before reverting to Pikabot. Since mid-January 2024, researchers observed it being used almost exclusively by TA578 in email threat campaigns. Campaign details TA577 TA577 was only observed using Latrodectus in three campaigns, all occurring in November 2023. Notably, a campaign that occurred on 24 November 2023 deviated from previously observed TA577 campaigns. The actor did not use thread hijacking, but instead used contained a variety of different subjects with URLs in the email body. The URLs led to the download of a JavaScript file. If executed, the JavaScript created and ran several BAT files that leveraged curl to execute a DLL and ran it with the export “scab”. Figure 1: Example TA577 campaign delivering Latrodectus. On 28 November 2023, Proofpoint observed the last TA577 Latrodectus campaign. The campaign began with thread hijacked messages that contained URLs leading to either zipped JavaScript files or zipped ISO files. The zipped JavaScript file used curl to download and execute Latrodectus. The zipped ISO file contained a LNK file used to execute the embedded DLL, Latrodectus. Both attack chains started the malware with the export “nail”. TA578 Since mid-January 2024, Latrodectus has been almost exclusively distributed by TA578. This actor typically uses contact forms to initiate a conversation with a target. In one campaign observed on 15 December 2023, Proofpoint observed TA578 deliver the Latrodectus downloader via a DanaBot infection. This December campaign was the first observed use of TA578 distributing Latrodectus. On 20 February 2024, Proofpoint researchers observed TA578 impersonating various companies to send legal threats about alleged copyright infringement. The actor filled out a contact form on multiple targets\' websites, with text containing unique URLs and included in the URI both the domain of the site that initiated the contact form (the target), and the name of the impersonated company (to further the legitimacy | Ransomware Malware Tool Threat Prediction | ★★★ | |

The 2023 Internet Crime Report from the FBI\'s Internet Crime Complaint Center (IC3) is out. And for defenders, it\'s a troubling read. The FBI saw only a minor uptick in reported cybercrime complaints last year from the American public. On the surface, this seems like positive news. There were only 79,474 more complaints filed than in 2022. However, that total is much more significant when you consider the potential losses from cybercrime. Losses surpassed $12.5 billion last year, a 22% increase from 2022 and a new record high. That staggering figure is part of a far more complex story about cybercrime in 2023. The report notes that: Investment fraud losses surged, jumping from $3.31 billion in 2022 to $4.57 billion in 2023-a 38% increase Business email compromise (BEC) cases were a top concern, with 21,489 complaints and adjusted losses exceeding $2.9 billion-up 7.4% from 2022 The allure of cryptocurrency played a pivotal role in both investment fraud and BEC incidents Tech support scams were the third-costliest cybercrime category among the crime types that the IC3 tracks In this post, we will examine these trends in more detail. And we will explain how Proofpoint can help businesses improve their defenses and meet these threats head-on. Complaints and losses from cybercrime reported over the last five years. (Source: FBI\'s IC3 2023 Internet Crime Report.) The rise of investment fraud Investment scams have become the most reported and costliest type of crime that the IC3 tracks. In these scams, bad actors lure victims with promises of big returns on investments. Attackers have been targeting cryptocurrency investors, in particular. The rise of this fraud highlights why due diligence and user self-awareness is so important. Users need to think twice and use caution when they are approached with investment opportunities, especially those that relate to cryptocurrencies. Investment fraud losses reported over the last five years. (Source: FBI\'s IC3 2023 Internet Crime Report.) An escalation in BEC threats BEC is the second-most prevalent cyberthreat highlighted in the latest Internet Crime Report. The actors behind these scams aim to deceive users and businesses into making unauthorized fund transfers or divulging corporate information. These attacks involve sophisticated tactics like: The compromise of legitimate business email accounts Social engineering attacks Impersonation scams As more people use cryptocurrency exchanges and rely on third-party payment processors, it\'s increasingly important to stop BEC threats before they reach users. There is also a pressing need for automated remediation and heightened user vigilance to protect against these threats. Vulnerable populations at risk for impersonation scams The FBI\'s IC3 reports that impersonation scams led to over $1.3 billion in losses last year. To carry out these scams, bad actors use deceptive tactics, like directing victims to send cash through shipping companies or online wire services. Adults over the age of 60 accounted for half of tech support scams last year. This amounted to $3.6 billion in losses. Individuals 30-39 years old were most likely to report these incidents to the FBI\'s IC3. The prevalence of impersonation scams underscores the need to raise awareness among the vulnerable populations that are targeted by attackers. Understanding this risk will help them to be more wary and avoid becoming victims. Ransomware attacks Ransomware attacks encrypt data and cause service disruptions and financial losses. They are also a persistent threat. The FBI\'s IC3 received over 2,800 complaints about this attack type last year. Reported losses from these incidents exceeded $59.6 million-an 18% increase from 2022. To understand just how costly these attacks can be, consider the plight of MGM Resorts. In September 2023, a targeted ransomware attack cost the entertainment giant over $100 million.

2024-03-11 06:00:16 | How Proofpoint aide les agences gouvernementales fédérales à se défendre contre les cybercriminels et les menaces d'initiés How Proofpoint Helps Federal Government Agencies Defend Against Cybercriminals and Insider Threats (lien direct) |
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 | ★★★ | |

2024-03-04 06:00:36 | La chaîne d'attaque inhabituelle de TA577 \\ mène au vol de données NTLM TA577\\'s Unusual Attack Chain Leads to NTLM Data Theft (lien direct) |
Ce qui s'est passé Proofpoint a identifié l'acteur de menace cybercriminale notable TA577 en utilisant une nouvelle chaîne d'attaque pour démontrer un objectif inhabituellement observé: voler des informations d'authentification NT LAN Manager (NTLM).Cette activité peut être utilisée à des fins de collecte d'informations sensibles et pour permettre l'activité de suivi. Proofpoint a identifié au moins deux campagnes en tirant parti de la même technique pour voler des hachages NTLM les 26 et 27 février 2024. Les campagnes comprenaient des dizaines de milliers de messages ciblant des centaines d'organisations dans le monde.Les messages sont apparus sous forme de réponses aux e-mails précédents, appelés détournement de fil, et contenaient des pièces jointes HTML zippées. Exemple de message utilisant le détournement de thread contenant une pièce jointe zippée contenant un fichier HTML. Chaque pièce jointe .zip a un hachage de fichiers unique, et les HTML dans les fichiers compressés sont personnalisés pour être spécifiques pour chaque destinataire.Lorsqu'il est ouvert, le fichier HTML a déclenché une tentative de connexion système à un serveur de blocs de messages (SMB) via un actualisation Meta à un schéma de fichier URI se terminant par .txt.Autrement dit, le fichier contacterait automatiquement une ressource SMB externe appartenant à l'acteur de menace.ProofPoint n'a pas observé la livraison de logiciels malveillants de ces URL, mais les chercheurs évaluent à la grande confiance que l'objectif de Ta577 \\ est de capturer les paires de défi / réponse NTLMV2 du serveur SMB pour voler des hachages NTLM en fonction des caractéristiques de la chaîne d'attaque et des outils utilisés. Exemple HTML contenant l'URL (en commençant par «File: //») pointant vers la ressource SMB. Ces hachages pourraient être exploités pour la fissuration du mot de passe ou faciliter les attaques "pass-the-hash" en utilisant d'autres vulnérabilités au sein de l'organisation ciblée pour se déplacer latéralement dans un environnement touché.Les indications à l'appui de cette théorie comprennent des artefacts sur les serveurs SMB pointant vers l'utilisation de l'impaquette de boîte à outils open source pour l'attaque.L'utilisation d'Impacket sur le serveur SMB peut être identifiée par le défi du serveur NTLM par défaut "aaaaaaaaaaaaaaaaa" et le GUID par défaut observé dans le trafic.Ces pratiques sont rares dans les serveurs SMB standard. Capture de paquets observée (PCAP) de la campagne TA577. Toute tentative de connexion autorisée à ces serveurs SMB pourrait potentiellement compromettre les hachages NTLM, ainsi que la révélation d'autres informations sensibles telles que les noms d'ordinateurs, les noms de domaine et les noms d'utilisateur dans un texte clair. Il est à noter que TA577 a livré le HTML malveillant dans une archive zip pour générer un fichier local sur l'hôte.Si le schéma de fichiers URI était envoyé directement dans l'organisme de messagerie, l'attaque ne fonctionnerait pas sur les clients d'Outlook Mail patchés depuis juillet 2023. La désactivation de l'accès des clients à SMB n'atteint pas l'attaque, car le fichier doit tenter de s'authentifier auprès du serveur externe SMB ServerPour déterminer s'il doit utiliser l'accès des clients. Attribution TA577 est un acteur de menace de cybercriminalité éminent et l'un des principaux affiliés de QBOT avant la perturbation du botnet.Il est considéré comme un courtier d'accès initial (IAB) et Proofpoint a associé des campagnes TA577 avec des infections de ransomware de suivi, notamment Black Basta.Récemment, l'acteur favorise Pikabot comme charge utile initiale. Pourquoi est-ce important Proof Point observe généralement TA577 menant des attaques pour livrer des logiciels malveillants et n'a jamais observé cet acteur de menace démontrant la chaîne d'attaque utilisée pour voler des informations d'identification NTLM observées le 26 février.Récemment, TA577 a été observé pour fou | Ransomware Malware Tool Vulnerability Threat | ★★ | |

We often-and justifiably-associate cyberattacks with technical exploits and ingenious hacks. But the truth is that many breaches occur due to the vulnerabilities of human behavior. That\'s why Proofpoint has gathered new data and expanded the scope of our 2024 State of the Phish report. Traditionally, our annual report covers the threat landscape and the impact of security education. But this time, we\'ve added data on risky user behavior and their attitudes about security. We believe that combining this information will help you to: Advance your cybersecurity strategy Implement a behavior change program Motivate your users to prioritize security This year\'s report compiles data derived from Proofpoint products and research, as well as from additional sources that include: A commissioned survey of 7,500 working adults and 1,050 IT professionals across 15 countries 183 million simulated phishing attacks sent by Proofpoint customers More than 24 million suspicious emails reported by our customers\' end users To get full access to our global findings, you can download your copy of the 2024 State of the Phish report now. Also, be sure to register now for our 2024 State of the Phish webinar on March 5, 2024. Our experts will provide more insights into the key findings and answer your questions in a live session. Meanwhile, let\'s take a sneak peek at some of the data in our new reports. Global findings Here\'s a closer look at a few of the key findings in our tenth annual State of the Phish report. Survey of working adults In our survey of working adults, about 71%, said they engaged in actions that they knew were risky. Worse, 96% were aware of the potential dangers. About 58% of these users acted in ways that exposed them to common social engineering tactics. The motivations behind these risky actions varied. Many users cited convenience, the desire to save time, and a sense of urgency as their main reasons. This suggests that while users are aware of the risks, they choose convenience. The survey also revealed that nearly all participants (94%) said they\'d pay more attention to security if controls were simplified and more user-friendly. This sentiment reveals a clear demand for security tools that are not only effective but that don\'t get in users\' way. Survey of IT and information security professionals The good news is that last year phishing attacks were down. In 2023, 71% of organizations experienced at least one successful phishing attack compared to 84% in 2022. The bad news is that the consequences of successful attacks were more severe. There was a 144% increase in reports of financial penalties. And there was a 50% increase in reports of damage to their reputation. Another major challenge was ransomware. The survey revealed that 69% of organizations were infected by ransomware (vs. 64% in 2022). However, the rate of ransom payments declined to 54% (vs. 64% in 2022). To address these issues, 46% of surveyed security pros are increasing user training to help change risky behaviors. This is their top strategy for improving cybersecurity. Threat landscape and security awareness data Business email compromise (BEC) is on the rise. And it is now spreading among non-English-speaking countries. On average, Proofpoint detected and blocked 66 million BEC attacks per month. Other threats are also increasing. Proofpoint observed over 1 million multifactor authentication (MFA) bypass attacks using EvilProxy per month. What\'s concerning is that 89% of surveyed security pros think MFA is a “silver bullet” that can protect them against account takeover. When it comes to telephone-oriented attack delivery (TOAD), Proofpoint saw 10 million incidents per month, on average. The peak was in August 2023, which saw 13 million incidents. When looking at industry failure rates for simulated phishing campaigns, the finance industry saw the most improvement. Last year the failure rate was only 9% (vs. 16% in 2022). “Resil | Ransomware Tool Vulnerability Threat Studies Technical | ★★★★ | |

What happened Proofpoint researchers identified the return of Bumblebee malware to the cybercriminal threat landscape on 8 February 2024 after a four-month absence from Proofpoint threat data. Bumblebee is a sophisticated downloader used by multiple cybercriminal threat actors and was a favored payload from its first appearance in March 2022 through October 2023 before disappearing. In the February campaign, Proofpoint observed several thousand emails targeting organizations in the United States with the subject "Voicemail February" from the sender "info@quarlesaa[.]com" that contained OneDrive URLs. The URLs led to a Word file with names such as "ReleaseEvans#96.docm" (the digits before the file extension varied). The Word document spoofed the consumer electronics company Humane. Screenshot of the voicemail-themed email lure. Screenshot of the malicious Word document. The document used macros to create a script in the Windows temporary directory, for example "%TEMP%/radD7A21.tmp", using the contents of CustomDocumentProperties SpecialProps, SpecialProps1, SpecialProps2 and SpecialProps3. The macro then executed the dropped file using "wscript". Inside the dropped temporary file was a PowerShell command that downloads and executes the next stage from a remote server, stored in file “update_ver”: The next stage was another PowerShell command which in turn downloaded and ran the Bumblebee DLL. The Bumblebee configuration included: Campaign ID: dcc3 RC4 Key: NEW_BLACK It is notable that the actor is using VBA macro-enabled documents in the attack chain, as most cybercriminal threat actors have nearly stopped using them, especially those delivering payloads that can act as initial access facilitators for follow-on ransomware activity. In 2022, Microsoft began blocking macros by default, causing a massive shift in the landscape to attack chains that began using more unusual filetypes, vulnerability exploitation, combining URLs and attachments, chaining scripting files, and much more. Another noteworthy feature of this campaign is that the attack chain is significantly different from previously observed Bumblebee campaigns. Examples used in prior campaigns that distributed Bumblebee with the “NEW_BLACK” configuration included: Emails that contained URLs leading to the download of a DLL which, if executed, started Bumblebee. Emails with HTML attachments that leveraged HTML smuggling to drop a RAR file. If executed, it exploited the WinRAR vulnerability CVE-2023-38831 to install Bumblebee. Emails with zipped, password-protected VBS attachments which, if executed, used PowerShell to download and execute Bumblebee. Emails that contained zipped LNK files to download an executable file. If executed, the .exe started Bumblebee. Out of the nearly 230 Bumblebee campaigns identified since March 2022, only five used any macro-laden content; four campaigns used XL4 macros, and one used VBA macros. Attribution At this time Proofpoint does not attribute the activity to a tracked threat actor. The voicemail lure theme, use of OneDrive URLs, and sender address appear to align with previous TA579 activities. Proofpoint will continue to investigate and may attribute this activity to a known threat actor in the future. Proofpoint assesses with high confidence Bumblebee loader can be used as an initial access facilitator to deliver follow-on payloads such as ransomware. Why it matters Bumblebee\'s return to the threat landscape aligns with a surge of cybercriminal threat activity after a notable absence of many threat actors and malware. Recently, two threat actors-tax-themed actor TA576 and the sophisticated TA866-appeared once again in email campaign data after months-long gaps in activity. Post-exploitation operator TA582 and aviation and aerospace targeting ecrime actor TA2541 both reappeared in the threat landscape in late January after being absent since the end of November.

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. Compromised accounts that have uncontrolled access may be able to exfiltrate sensitive data or upload malware like ransomware. So, when you know what your suppliers can (and can\'t) access, you can identify a data breach faster.

2024-02-09 06:00:24 | Offensif et défensif: renforcer la sensibilisation à la sécurité avec deux approches d'apprentissage puissantes Offensive and Defensive: Build Security Awareness with Two Powerful Learning Approaches (lien direct) |
“Offensive” security awareness and “defensive” security awareness are two learning approaches that you can use to build a robust security culture in your company. They involve applying different strategies to educate your employees about threats and how they can respond to them safely. You may have heard the terms “offensive cybersecurity” and “defensive cybersecurity.” You use defensive tools and techniques to strengthen security vulnerabilities. And with offensive tools and techniques, you focus on identifying those vulnerabilities before attackers find them first. How do defensive and offensive approaches apply to security awareness? Here\'s a quick overview: With a defensive approach, users learn the fundamentals of security. With an offensive approach, users learn how to protect themselves and the business against future threats. Let\'s use a sports analogy here. You can actively learn to be a defensive goalie and block threats. Then, you can take your skills up a level and learn to score points with protective techniques. With Proofpoint Security Awareness, our industry-leading threat intelligence informs both approaches. We help people learn how to defend against current threats. And we give them the tools for taking offensive action against future threats. Live-action series about Insider Threats. (play video) Defensive security awareness: set the foundation We all have to start with the basics, right? With defensive security awareness, you teach people the fundamentals of security and set the stage for safe behavior. This training is often reactive. It enables people to respond to immediate threats and incidents as they arise. At Proofpoint, we believe in using behavioral science methodologies, like adaptive learning and contextual nudges. We combine this with a threat-driven approach, weaving trend analysis and insights about recent security breaches into our training. A personalized adaptive framework The adaptive learning framework is a personalized defensive approach to training. It recognizes that everyone learns differently; it is the opposite of a one-size-fits-all approach. You can teach security fundamentals in a way that is meaningful for each person based on what they know, what they might do and what they believe. This framework lets you drive behavior change with education that is tailored to each person\'s needs. That can include their professional role, industry, content style and native language. The learner can engage with a wide variety of styles and materials. And each training is tied to a specific learning objective. Adaptive learning recognizes that people learn best in short bursts that are spread over time. Our microlearning video modules are under three minutes, and our nano-learning videos are under one minute. These formats give people the flexibility to learn at their own pace. For instance, our “You\'re Now a Little Wiser” nano series offers bite-size training on topics such as data protection to help users learn about specific threats. Screenshots from a one-minute nano-learning video. Contextual nudges and positive reinforcement Training is essential if you want to build a robust security culture. But it is not enough to change behavior fully. Here is where contextual nudges play a vital role in helping to reinforce positive behavior habits once they are formed. These deliberate interventions are designed to shape how people behave. Nudges are rooted in a deep understanding of human behavior. They can move people toward making better decisions, often without them realizing it. They are gentle reminders that can guide people toward creating optimal outcomes. That, in turn, helps to foster a defensive security-conscious culture in your company. It is important to find the respectful balance of nudging people toward secure behaviors without being too intrusive or complex.

2024-02-06 05:00:20 | Comment les cybercriminels augmentent-ils le privilège et se déplacent-ils latéralement? How Do Cybercriminals Escalate Privilege and Move Laterally? (lien direct) |
If you want to understand how cybercriminals cause business-impacting security breaches, the attack chain is a great place to start. The eight steps of this chain generalize how a breach progresses from start to finish. The most impactful breaches typically follow this pattern: Steps in the attack chain. In this blog post, we will simplify the eight steps of an attack into three stages-the beginning, middle and end. Our focus here will primarily be on the middle stage-info gathering, privilege escalation and lateral movement, which is often the most challenging part of the attack chain to see and understand. The middle steps are often unfamiliar territory, except for the most highly specialized security practitioners. This lack of familiarity has contributed to significant underinvestment in security controls required to address attacks at this stage. But before we delve into our discussion of the middle, let\'s address the easiest stages to understand-the beginning and the end. The beginning of the attack chain A cyberattack has to start somewhere. At this stage, a cybercriminal gains an initial foothold into a target\'s IT environment. How do they do this? Mainly through phishing. A variety of tactics are used here including: Stealing a valid user\'s login credentials Luring a user into installing malicious software, such as Remote Access Trojans (RATs) Calling the company\'s help desk to socially engineer the help desk into granting the attacker control over a user\'s account Much ink has been spilled about these initial compromise techniques. This is why, in part, the level of awareness and understanding by security and non-security people of this first stage is so high. It is fair to say that most people-IT, security and everyday users-have personally experienced attempts at initial compromise. Who hasn\'t received a phishing email? A great deal of investment goes into security tools and user training to stop the initial compromise. Think of all the security technologies that exist for that purpose. The list is very long. The end of the attack chain Similarly, the level of awareness and understanding is also very high around what happens at the end of the attack chain. As a result, many security controls and best practices have also been focused here. Everyone-IT, security and even everyday users-understands the negative impacts of data exfiltration or business systems getting encrypted by ransomware attackers. Stories of stolen data and ransomed systems are in the news almost daily. Now, what about the middle? The middle is where an attacker attempts to move from the initially compromised account(s) or system(s) to more critical business systems where the data that\'s worth exfiltrating or ransoming is stored. To most people, other than red teamers, pen testers and cybercriminals, the middle of the attack chain is abstract and unfamiliar. After all, regular users don\'t attempt to escalate their privileges and move laterally on their enterprise network! These three stages make up the middle of the attack chain: Information gathering. This includes network scanning and enumeration. Privilege escalation. During this step, attackers go after identities that have successively higher IT system privileges. Or they escalate the privilege of the account that they currently control. Lateral movement. Here, they hop from one host to another on the way to the “crown jewel” IT systems. Steps in the middle of the attack chain. Relatively few IT or security folks have experience with or a deep understanding of the middle of the attack chain. There are several good reasons for this: Most security professionals are neither red teamers, pen testers, nor cybercriminals. The middle stages are “quiet,” unlike initial compromise-focused phishing attacks or successful ransomware attacks, which are very “loud” by comparison. Unlike the front and back end of the attack chain, there has been little coverage about how these steps | Ransomware Malware Tool Vulnerability Threat | ★★★ | |

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.

2024-02-01 06:00:12 | Le pare-feu humain: Pourquoi la formation de sensibilisation à la sécurité est une couche de défense efficace The Human Firewall: Why Security Awareness Training Is an Effective Layer of Defense (lien direct) |
Do security awareness programs lead to a quantifiable reduction in risk? Do they directly impact a company\'s security culture? In short, are these programs effective? The answer to these questions is a resounding yes! With 74% of all data breaches involving the human element, the importance of educating people to help prevent a breach cannot be understated. However, for training to be effective, it needs to be frequent, ongoing and provided to everyone. Users should learn about: How to identify and protect themselves from evolving cyberthreats What best practices they can use to keep data safe Why following security policies is important In this blog post, we discuss the various ways that security awareness training can have a positive impact on your company. We also discuss how to make your program better and how to measure your success. Security awareness training effectiveness Let\'s look at three ways that security awareness training can help you boost your defenses. 1. Mitigate your risks By teaching your team how to spot and handle threats, you can cut down on data breaches and security incidents. Our study on the effects of using Proofpoint Security Awareness showed that many companies saw up to a 40% decrease in the number of harmful links clicked by users. Think about this: every click on a malicious link could lead to credential theft, a ransomware infection, or the exploitation of a zero-day vulnerability. So, an effective security awareness program essentially reduces security incidents by a similar amount. Want more evidence about how important it is? Just check out this study that shows security risks can be reduced by as much as 80%. Here is more food for thought. If a malicious link does not directly result in a breach, it must still be investigated. The average time to identify a breach is 204 days. So, if you can reduce the number of incidents you need to investigate, you can see real savings in time and resources. 2. Comply with regulations Security awareness education helps your company comply with data regulations, which are always changing. This can help you avoid hefty fines and damage to your reputation. In many cases, having a security awareness program can keep you compliant with several regulations. This includes U.S. state privacy laws, the European Union\'s GDPR and other industry regulations. 3. Cultivate a strong security culture An effective security awareness program doesn\'t have to be all doom and gloom. Done right, it can help you foster a positive security culture. More than half of users (56%) believe that being recognized or rewarded would make their company\'s security awareness efforts more effective. But only 8% of users say that their company provides them with incentives to practice “good” cybersecurity behavior. When you make security fun through games, contests, and reward and recognition programs, you can keep your employees engaged. You can also motivate them to feel personally responsible for security. That, in turn, can inspire them to be proactive about keeping your critical assets safe. Finally, be sure to incorporate security principles into your company\'s core values. For example, your business leaders should regularly discuss the importance of security. That will help users to understand that everyone plays a vital role in keeping the business safe. How to make your security awareness program effective The verdict is clear. Security awareness programs can tangibly reduce organizational risks. When asked about the connection between their security awareness efforts and their company\'s cybersecurity resilience, a resounding 96% of security professionals say that there is more than just a strong link. They say that it\'s either a direct result of security training or that training is a strong contributor. Let\'s discuss how you can make your program more effective.

Gather \'round, cyber friends, and I\'ll let you in on a little secret: no one knows what the Next Big Thing on the threat landscape will be. But we can look back on 2023, identify notable changes and actor behaviors, and make educated assessments about what 2024 will bring. This month on the DISCARDED podcast my co-host Crista Giering and I sat down with our Threat Research leaders Daniel Blackford, Alexis Dorais-Joncas, Randy Pargman, and Rich Gonzalez, leaders of the ecrime, advanced persistent threat (APT), threat detection, and Emerging Threats teams, respectively. We discussed what we learned over the last year, and what\'s on the horizon for the future. While the discussions touched on different topics and featured different opinions on everything from artificial intelligence (AI) to living off the land binaries (LOLBins) to vulnerability exploitation to ransomware, there were some notable themes that are worth writing down. We can\'t say for sure what surprises are in store, but with our cyber crystals balls fully charged – and a deep knowledge of a year\'s worth of threat actor activity based on millions of email threats per day – we can predict with high confidence what\'s going to be impactful in the coming year. 1: Quick response (QR) codes will continue to proliferate 2023 was the year of the QR code. Although not new, QR codes burst on the scene over the last year and were used in many credential phishing and malware campaigns. The use was driven by a confluence of factors, but ultimately boiled down to the fact that people are now way more accustomed to scanning QR codes for everything from instructions to menus. And threat actors are taking advantage. Proofpoint recently launched new in-line sandboxing capabilities to better defend against this threat, and our teams anticipate seeing more of it in 2024. Notably, however, Dorais-Joncas points out that QR codes still just exist in the realm of ecrime – APT actors have not yet jumped on the QR code bandwagon. (Although, some of those APT actors bring ecrime energy to their campaigns, so it\'s possible they may start QR code phishing, too.) 2: Zero-day and N-day vulnerability exploitation A theme that appeared throughout our conversations was the creative use of vulnerabilities – both known and unreported – in threat actor activity. APT actors used a wide variety of exploits, from TA473 exploiting publicly-facing webmail servers to espionage actors using a zero-day in an email security gateway appliance that ultimately forced users to rip out and reinstall physical hardware. But ecrime actors also exploited their share of vulnerabilities, including the MOVEit file transfer service vulnerability from the spring of 2023 that had cascading repercussions, and the ScreenConnect flaw announced in the fall of 2023 – both of which were used by ecrime actors before being officially published. Proofpoint anticipates vulnerability exploitation will continue, driven in part by improved defense making old school techniques – like macro-enabled documents – much less useful, as well as the vast financial resources now available to cybercriminals that were once just the domain of APT. Pargman says the creativity from ecrime threat actors is a direct response of defenders imposing cost on our adversaries. 3: Continuing, unexpected behavior changes Avid listeners of the podcast know I have regularly said the ecrime landscape is extremely chaotic, with TA577 demonstrating the most chaotic vibes of them all. The tactics, techniques, and procedures (TTPs) of some of the most sophisticated actors continue to change. The cost imposed on threat actors that Pargman mentioned – from law enforcement takedowns of massive botnets like Qbot to improved detections and automated defenses – have forced threat actors, cybercriminals in particular, to regularly change their behaviors to figure out what is most effective. For example, recently Proofpoint has observed the increased use of: traffic dis | Ransomware Malware Tool Vulnerability Threat Prediction | ★★★ | |

2024-01-09 11:57:12 | L'augmentation préoccupante des attaques centrées sur l'identité: tendances et faits The Concerning Rise in Identity-Centric Attacks: Trends and Facts (lien direct) |
Identity threats are by no means a new type of crime. But in today\'s increasingly digitized world, there are more opportunities for bad actors to steal identities and engage in identity-centric attacks than ever before. Unfortunately, user identities are tough for businesses to protect. The fact that these types of attacks are skyrocketing is evidence of that-in the past year alone the Identity Defined Security Alliance reports that a whopping 84% of companies experienced an identity-related security breach. In this post, we\'ll take a look at identity attack statistics and trends and provide some recent case studies to illustrate how some attacks work. We\'ll also highlight one of the most important identity threat facts-that the human element plays a crucial role in the success of these attacks. Understanding identity-centric attacks There are many types of identity attacks. When most people think of these types of crimes, they often imagine traditional identity theft scenarios: Financial identity theft, where a criminal gains access to a victim\'s financial data, like their credit card details, bank account numbers or Social Security number, to make unauthorized purchases, withdraw funds or open new accounts. Tax identity theft, where a bad actor uses a victim\'s personal information to file false tax returns and claim refunds, diverting the money to their own accounts. Employment identity theft, where a fraudster uses a victim\'s identity to get a job, potentially causing issues for that person when discrepancies arise in their employment and tax records. But identity-based attacks also target enterprises and their online users. The cybercriminals behind these attacks might aim to steal sensitive data, siphon off funds, damage or disrupt systems, deploy ransomware or worse. Those are the types of identity attacks we\'re covering here. Identity threat trends and tactics In short, identity-centric attacks are a practical calculation by bad actors: Why would they invest their time and resources to build exploits to help them get in through a virtual back door when they can just walk through the front door? But before they reap the rewards, they still have some legwork to do. Here are a few techniques that cybercriminals use to progress identity-based attacks against businesses and their users: MFA bypass attacks. Many businesses today use multifactor authentication (MFA) to protect the account of their users. It\'s more secure than using passwords alone. But of course, bad actors have found new ways to bypass commonly used MFA methods. MFA fatigue attacks are one example. People-activated malware. People often give life to malware when they fall for a phishing scam or other social engineering tactics. Malware can appear in the form of a .zip file, QR code, .html link, MS Office file and more-there are at least 60 known techniques to plant people-activated malware on corporate networks. Active Directory (AD) attacks. Most enterprises today use AD as a primary method for directory services like user authentication and authorization. Cybercriminals are keen to target AD, which touches almost every place, person and device on a network. This approach works very well, too-more than half of identity-related breaches can be traced back to AD. Cached credentials harvesting. Cached credentials are commonly stored on endpoints, in memory, in the registry, in a browser or on disk. Attackers use various tools and techniques to collect these credentials and gain access to more privileged identities. Once they have harvested these credentials, they can use them to move laterally and log into different applications. Adversaries are likely to find a good “crop” when they are harvesting cached credentials. Recent research from Proofpoint found that more than one in 10 endpoints have exposed privileged account passwords, making it one of the most common identity risks. Keep in mind that cybercriminals are always innovating, and they are quick to build or adopt tools that | Ransomware Malware Tool Threat Studies | Uber | ★★ |

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). Staying ahead of generative AI attacks AI-powered systems are promoted as tools to help us work faster, and they are transforming businesses and industries.

2024-01-02 08:41:00 | 6 Exigences d'assurance cybersécurité Votre entreprise doit être prête à répondre 6 Cybersecurity Insurance Requirements Your Business Should Be Ready To Meet (lien direct) |
Every year, more companies are finding out firsthand how damaging a cyberattack can be. Research for the 2023 State of the Phish report from Proofpoint found that 30% of companies that were successfully attacked experienced a direct monetary loss. That\'s an increase of 76% year over year. And costs for these attacks are rising. IBM reports that the global average cost of a data breach went up by 15% over the last three years, hitting $4.45 million in 2023. Concerns about costs and risks mean that more companies than ever are buying cyber insurance. A World Economic Forum survey found that 71% of organizations have cyber insurance. And Allied Market Research projects that the global cyber insurance market, which is currently valued at $12.5 billion, will reach $116.7 billion by 2032. Investing in cyber insurance for your business can be a wise strategy. For one, it helps you to transfer some of the financial risks of a cybersecurity event to your insurance provider. But the cyber insurance landscape is changing. You should know that getting the coverage you want might be a challenge, and you will need to meet an array of cybersecurity insurance requirements. In this blog post, we\'ll cover six of the most common requirements you\'ll likely need to fulfill. What is cyber insurance-and what does it cover? But first, let\'s take a closer look at what cyber insurance is and why it is important. Also known as cyber liability insurance, this relatively new type of insurance helps to protect businesses and individuals from the negative impacts of cybersecurity events. It generally covers: Loss of data and the associated recovery Loss of revenue due to business interruption Loss of transferred funds from cyberattacks, like business email compromise (BEC) and phishing Loss of funds from ransomware and extortion Many policies also cover the aftermath and follow-up events associated with a data breach. This includes the costs associated with identifying and notifying victims, credit monitoring for victims and forensics expertise, to name a few. Why is cyber insurance important? For many companies, cyber insurance is an essential part of their risk management strategy. It covers many costs related to cyber events, such as legal expenses and fees for compliance violations. Depending on the policy, it might also cover: Ransomware attacks. If your business is hit with a ransomware attack, you may face demands for payment to unlock your systems. Or you may need to pay a ransom to prevent the release of sensitive data. In certain cases, cyber insurance can help cover ransom payments. Incident response and recovery. Cybersecurity insurance can help with the cost of investments you may need to make after an attack. For example, you may need to hire experts, conduct forensic investigations, and implement tools and measures to prevent future attacks. Business disruption. This may include lost revenue during downtime. This coverage can help your business stay afloat financially and continue operating in the wake of a cyber event. Want more details on the benefits of cyber insurance? Download the Proofpoint presentation, “Cyber Insurance: Facts, Figures and Policy Fundamentals.” Examples of common cyber insurance requirements As noted earlier, getting coverage is more complicated than it used to be. Because security breaches are so costly and cybercrime is so common, many insurers have become more stringent in their underwriting processes. Some have lowered caps for payouts and narrowed their coverage offerings as well. This means that the requirements your business may be expected to meet will be fairly complex. Every provider will likely conduct a risk assessment to determine if you qualify for cyber insurance. The process will help them to determine how much coverage they can offer you, and what you\'ll need to pay for it. The risk assessment might be as quick and simple as a questionnaire or as complex and time-consuming as a third-party audit. Here are six examples | Ransomware Data Breach Tool Threat | ★★★ | |

2023-12-15 06:00:41 | Comment empêcher les attaques basées sur l'identité avec ITDR How to Prevent Identity-Based Attacks with ITDR (lien direct) |
Identity-based attacks are on the rise. Research from the Identity Defined Security Alliance found that 84% of businesses experienced an identity-related breach in the past year. While that\'s a huge percentage, it\'s not all that surprising. Just consider how focused attackers have been in recent years on gaining access to your user\'s identities. In the latest Verizon 2023 Data Breach Investigations Report, Verizon found that 40% of all data breaches in 2022 involved the theft of credentials which is up from 31% in 2021. With access to just one privileged account an attacker can move around undetected on a company\'s network and cause havoc. When they look like the right employee, they have the freedom to do almost anything, from stealing sensitive data to launching ransomware attacks. What\'s worse, attackers usually have tools that make it fast and easy to exploit stolen credentials, escalate privilege and move laterally. That makes this type of attack all the more appealing. There are a bevy of cybersecurity tools that are supposed to protect companies from these attacks. So why do they fall short? The simple answer is that it\'s not their job-at least not completely. Take tools used for identity access management (IAM) as an example. Their role is to administer identities and manage their access to applications and resources. They don\'t detect malicious activity after a “legitimate” user has been authenticated and authorized. And tools for anomaly detection, like security information and event management (SIEM) systems, alert on abnormal or malicious user activity. But they are even less capable of flagging attempts at lateral movement and privilege escalation. As a result, these tools tend to generate high levels of false positives, which overwhelm security teams. However, there is a way to address the security gaps these solutions aren\'t well equipped to cover. It\'s called identity threat detection and response, or ITDR for short. What is ITDR? ITDR is an umbrella term coined by Gartner to describe a new category of security tools and best practices that companies can use to detect and respond more effectively to identity-based attacks. ITDR protects the middle of the attack chain-the point where enterprise defenses are usually the weakest. ITDR tools offer robust analytics, integrations and visibility that can help you to: Detect, investigate and respond to active threats Stop privilege escalations Identify and halt lateral movement by attackers Reduce the identity-centric attack surface before the threat actor even arrives When you use ITDR, you\'re not replacing existing tools or systems for IAM and threat detection and response like privileged access management (PAM) or endpoint detection and response (EDR). Instead, you\'re complementing them. Those tools can continue to do what they do best while ITDR addresses the identity security gaps they\'re not designed to cover. How ITDR solutions work-and help to prevent identity-based attacks ITDR tools are designed to continuously monitor user behavior patterns across systems. They scan every endpoint-clients and servers, PAM systems and identity repositories-to look for unmanaged, misconfigured and exposed identities. With a holistic view of identity risks, your security team can remove key attack pathways through Active Directory (AD) that threat actors use to install ransomware and steal data. ITDR tools can help defenders stop identity attacks and proactively get rid of risks. They allow defenders to see exactly how attackers can access and use identities to compromise the business. Essentially, ITDR provides answers to these three critical questions: Whose identity provides an attack path? What is the identity threat blast radius, and the impact to my business? Are there any identity-based attacks in progress? Leading ITDR tools can help you catch adversaries in the act by planting deceptive content, or trip wires, throughout your environment that only attackers would in | Ransomware Data Breach Tool Vulnerability Threat | ★★ | |

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.

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 steps in the attack chain – stopping the 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 three steps of the attack chain: stop the initial compromise. In our previous posts, we have covered these attack types: Supplier compromise EvilProxy SocGholish E-signature phishing QR code phishing Telephone-oriented attack delivery (TOAD) In this installment we examine a payroll diversion threat that Proofpoint detected during a recent threat assessment. We also cover the typical attack sequence of payroll fraud and explain how Proofpoint uses multiple signals to detect and prevent these threats for our customers. Background Business email compromise (BEC) continues to grow in popularity and sophistication. The 2022 FBI Internet Crime Report notes that BEC attacks cost U.S. businesses $2.7 billion last year. The global figure is no doubt much higher. Ransomware victims, in contrast, lost just $34 million. Payroll diversion is a form of BEC. Typically, employees who have direct access to fulfilling payroll-related requests are prime targets. In these attacks, a bad actor pretends to be an employee who needs to update their direct deposit information. The new information is for an account that the bad actor owns. Once the fraudulent request is complete, the lost funds cannot be retrieved by the business. Payroll diversion fraud isn\'t a new form of BEC, but the frequency of this type of attack is on the rise. Proofpoint continues to see this type of threat getting through the defenses of other email security tools. Across all of our October 2023 threat assessments, we found that more than 400 of these threats got past 12 other email security tools. There are a few reasons why it\'s difficult for a lot of email security tools to detect or remediate these threats. The primary reason is because they don\'t usually carry malicious payloads like attachments or URLs. They also tend to be sent from personal email services-like Google, Yahoo and iCloud-and target specific users. Notably, API-based email security tools that scan for threats post-delivery are the most susceptible to not being able to detect or remediate this type of threat. This partly comes down to how they work. In order for them to be effective, they need security and IT teams to manually populate them with a dictionary of possible display names of all employees, which is a very time-consuming effort that is hard to scale. To avoid this, many organizations simply choose to enable display name prevention for their senior executives only. But bad actors behind payroll diversion don\'t just impersonate executives, they target anyone in the organization who can access corporate funds. In our example below, an attacker took advantage of this exact weakness. The scenario Proofpoint detected a payroll diversion attempt where the attacker posed as a non-executive employee. The email was sent to the director of human resources (HR) at a 300-person company in the energy and utilities industry. The company\'s incumbent email security tool delivered the message, and its API-based post-delivery remediation tool failed to detect and retract it. The threat: How did the attack happen? Here is a closer look at how this payroll diversion scam unfolded: 1. The deceptive message: The attacker sent a request to update their direct deposit information from an account that appeared to be a legitimate employee\'s personal email account. The original malicious message delivered to the recipient\'s inbox. 2. Payroll diversion attack sequence: If the recipient had engaged, the attacker\'s goal would have been to convince them to trans | Ransomware Tool Threat | Yahoo | ★★ |

2023-11-28 23:05:04 | Prédictions 2024 de Proofpoint \\: Brace for Impact Proofpoint\\'s 2024 Predictions: Brace for Impact (lien direct) |
In the ever-evolving landscape of cybersecurity, defenders find themselves navigating yet another challenging year. Threat actors persistently refine their tactics, techniques, and procedures (TTPs), showcasing adaptability and the rapid iteration of novel and complex attack chains. At the heart of this evolution lies a crucial shift: threat actors now prioritize identity over technology. While the specifics of TTPs and the targeted technology may change, one constant remains: humans and their identities are the most targeted links in the attack chain. Recent instances of supply chain attacks exemplify this shift, illustrating how adversaries have pivoted from exploiting software vulnerabilities to targeting human vulnerabilities through social engineering and phishing. Notably, the innovative use of generative AI, especially its ability to improve phishing emails, exemplifies a shift towards manipulating human behavior rather than exploiting technological weaknesses. As we reflect on 2023, it becomes evident that cyber threat actors possess the capabilities and resources to adapt their tactics in response to increased security measures such as multi-factor authentication (MFA). Looking ahead to 2024, the trend suggests that threats will persistently revolve around humans, compelling defenders to take a different approach to breaking the attack chain. So, what\'s on the horizon? The experts at Proofpoint provide insightful predictions for the next 12 months, shedding light on what security teams might encounter and the implications of these trends. 1. Cyber Heists: Casinos are Just the Tip of the Iceberg Cyber criminals are increasingly targeting digital supply chain vendors, with a heightened focus on security and identity providers. Aggressive social engineering tactics, including phishing campaigns, are becoming more prevalent. The Scattered Spider group, responsible for ransomware attacks on Las Vegas casinos, showcases the sophistication of these tactics. Phishing help desk employees for login credentials and bypassing MFA through phishing one-time password (OTP) codes are becoming standard practices. These tactics have extended to supply chain attacks, compromising identity provider (IDP) vendors to access valuable customer information. The forecast for 2024 includes the replication and widespread adoption of such aggressive social engineering tactics, broadening the scope of initial compromise attempts beyond the traditional edge device and file transfer appliances. 2. Generative AI: The Double-Edged Sword The explosive growth of generative AI tools like ChatGPT, FraudGPT and WormGPT bring both promise and peril, but the sky is not falling as far as cybersecurity is concerned. While large language models took the stage, the fear of misuse prompted the U.S. president to issue an executive order in October 2023. At the moment, threat actors are making bank doing other things. Why bother reinventing the model when it\'s working just fine? But they\'ll morph their TTPs when detection starts to improve in those areas. On the flip side, more vendors will start injecting AI and large language models into their products and processes to boost their security offerings. Across the globe, privacy watchdogs and customers alike will demand responsible AI policies from technology companies, which means we\'ll start seeing statements being published about responsible AI policies. Expect both spectacular failures and responsible AI policies to emerge. 3. Mobile Device Phishing: The Rise of Omni-Channel Tactics take Centre Stage A notable trend for 2023 was the dramatic increase in mobile device phishing and we expect this threat to rise even more in 2024. Threat actors are strategically redirecting victims to mobile interactions, exploiting the vulnerabilities inherent in mobile platforms. Conversational abuse, including conversational smishing, has experienced exponential growth. Multi-touch campaigns aim to lure users away from desktops to mobile devices, utilizing tactics like QR codes and fraudulent voice calls | Ransomware Malware Tool Vulnerability Threat Mobile Prediction Prediction | ChatGPT ChatGPT | ★★★ |

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. But some attackers deliver these messages through other methods, including smishing and vishing. Here are some typical strategies: Malicious links.

2023-11-21 08:35:02 | Prévenir les attaques de fatigue du MFA: sauvegarder votre organisation Preventing MFA Fatigue Attacks: Safeguarding Your Organization (lien direct) |
Gaining access to critical systems and stealing sensitive data are top objectives for most cybercriminals. Social engineering and phishing are powerful tools to help them achieve both. That\'s why multifactor authentication (MFA) has become such an important security measure for businesses and users. Without MFA as part of the user authentication process, it is much less challenging for an attacker with stolen credentials to authenticate a user\'s account. The primary goal of MFA is to reduce the risk of unauthorized access, especially in situations where passwords alone may not provide enough protection. Even if an attacker steals a user\'s password, with MFA they still need the second factor (and maybe others) to gain access to an account. Examples of MFA factors include biometrics, like fingerprints, and signals from user devices, like GPS location. MFA isn\'t a perfect solution, though-it can be bypassed. Adversaries are relentless in their efforts to undermine any security defenses standing in the way of their success. (The evolution of phish kits for stealing MFA tokens is evidence of that.) But sometimes, attackers will choose to take an in-your-face approach that is not very creative or technical. MFA fatigue attacks fall into that category. What are MFA fatigue attacks-and how do they work? MFA fatigue attacks, also known as MFA bombing or MFA spamming, are a form of social engineering. They are designed to wear down a user\'s patience so that they will accept an MFA request out of frustration or annoyance-and thus enable an attacker to access their account or device. Many people encounter MFA requests daily, or even multiple times per day, as they sign-in to various apps, sites, systems and platforms. Receiving MFA requests via email, phone or other devices as part of that process is a routine occurrence. So, it is logical for a user to assume that if they receive a push notification from an account that they know requires MFA, it is a legitimate request. And if they are very busy at the time that they receive several push notifications in quick succession to authenticate an account, they may be even more inclined to accept a request without scrutinizing it. Here\'s an overview of how an MFA attack works: A malicious actor obtains the username and password of their target. They can achieve this in various ways, from password-cracking tactics like brute-force attacks to targeted phishing attacks to purchasing stolen credentials on the dark web. The attacker then starts to send MFA notifications to the user continuously, usually via automation, until that individual feels overwhelmed and approves the login attempt just to make the requests stop. (Usually, the push notifications from MFA solutions require the user to simply click a “yes” button to authenticate from the registered device or email account.) Once the attacker has unauthorized access to the account, they can steal sensitive data, install malware and do other mischief, including impersonating the user they have compromised-taking their actions as far as they can or want to go. 3 examples of successful MFA fatigue attacks To help your users understand the risk of these attacks, you may want to include some real-world examples in your security awareness program on this topic. Here are three notable incidents, which are all associated with the same threat actor: Uber. In September 2022, Uber reported that an attacker affiliated with the threat actor group Lapsus$ had compromised a contractor\'s account. The attacker may have purchased corporate account credentials on the dark web, Uber said in a security update. The contractor received several MFA notifications as the attacker tried to access the account-and eventually accepted one. After the attacker logged in to the account, they proceeded to access other accounts, achieving privilege escalation. One action the attacker took was to reconfigure Uber\'s OpenDNS to display a graphic image on some of the company\'s internal sites. Cisco.

2023-11-10 07:55:46 | New Gartner & Reg;Rapport BEC: les recommandations sont entièrement prises en charge par Proofpoint New Gartner® BEC Report: Recommendations Are Fully Supported by Proofpoint (lien direct) |
Business email compromise (BEC) is costly. The latest Internet Crime Report from the FBI\'s Internet Crime Complaint Center notes that businesses lost more than $2.7 billion due to these scams in 2022. Another staggering statistic that is less reported: BEC losses were almost 80 times that of ransomware last year. The rate of BEC attacks and the average loss per incident are likely to keep climbing, which makes BEC an ongoing concern for businesses. A recent report by Gartner, How to Protect Organizations Against Business Email Compromise Phishing, offers companies several recommendations to help them reduce the risk of these attacks and minimize potential losses. Below, we share five top takeaways and key findings from this 2023 report. We also explain how Proofpoint can help protect your business against BEC attacks by linking what we do to Gartner\'s recommendations. 1. To combat BEC, businesses need to invest in email security rather than relying on endpoint protection Not all BEC scams contain a malicious payload like malware or malicious links. That\'s why endpoint protection and endpoint detection and response platforms are not effective defenses for these types of attacks. Gartner recommends: If you\'re a security and risk management leader who is responsible for infrastructure security, you can maximize your protection against BEC by seeking out and implementing artificial intelligence (AI)-based secure email gateway solutions. Look for solutions that offer: Advanced BEC phishing protection Behavioral analysis Impostor detection Internal email protection Proofpoint protects: Proofpoint believes that Gartner report\'s recommendation stems from the understanding that stopping BEC attacks before they reach a recipient\'s inbox is the best method to minimize risks. This strategy is at the heart of the Proofpoint Aegis threat protection platform. Proofpoint has used machine learning (ML) for more than two decades to detect email threats. We create the highest levels of BEC detection efficacy through our combination of AI/ML-driven behavioral analysis and rich threat intelligence. 2. Supplement email security with additional controls to reduce the risk of ATO Account takeover fraud (ATO) is often a feature in BEC attacks. It occurs when an adversary gains control of a legitimate account. To reduce the risk of ATO, businesses need to be able to recognize whether an email is from a genuine sender. Gartner recommends: Businesses should supplement their existing email security solutions with additional controls to further reduce the risk of BEC attacks like ATO and domain abuse. Proofpoint protects: To protect against account takeover, you need to identify accounts that might be compromised and automate remediation. If you rely solely on behavioral analytics to detect these accounts, you could end up with a high volume of false alerts. Proofpoint combines behavioral analysis with our rich threat intelligence to detect both compromised employee accounts and compromised third-party accounts. How Proofpoint helps when ATO occurs If an internal account has been compromised, a password reset isn\'t enough. Attackers in your environment can still manipulate third-party apps and gain persistent access to the account to wage attacks at will. Proofpoint TAP Account Takeover (TAP ATO) provides insights into what types of threats are targeting your users\' email accounts. And it provides you with the tools you need to take corrective action to protect a compromised account. TAP ATO correlates threat intelligence with artificial intelligence, ML and behavioral analytics to find malicious events across the email attack chain. It helps you see who is being attacked and how, and it provides automated remediation. How Proofpoint helps when supplier accounts are compromised Proofpoint Supplier Threat Protection gives you insight into which third-party and supplier accounts may be compromised.

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 | ★★ | |

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.

Ce qui s'est passé Les chercheurs de Proofpoint ont identifié TA571 livrant la variante fourchue de l'IceDID dans deux campagnes les 11 et 18 octobre 2023. Les deux campagnes comprenaient plus de 6 000 messages, chacun plus de 1 200 clients dans une variété d'industries dans le monde. Les e-mails dans les campagnes prétendaient être des réponses aux threads existants.Ceci est connu sous le nom de détournement de fil.Les e-mails contenaient 404 URL TDS liant au téléchargement d'une archive zip protégée par mot de passe avec le mot de passe répertorié dans l'e-mail.La chaîne d'attaque comprenait une série de contrôles pour valider le destinataire avant de livrer les archives zip.

Le fichier zip contenait un script VBS et un fichier texte bénin.Le script VBS, s'il est double de l'utilisateur, exécuté un chargeur fourchu icedid intégré à regsvr32.Le chargeur a à son tour téléchargé le bot icedid. L'utilisation de la variante iceide fourchue est inhabituelle, car elle n'a été observée que dans un petit nombre de campagnes.ProofPoint a d'abord identifié cette variante en février 2023. Une différence clé entre la variante iceide d'origine et la variante fourchue était l'élimination de la fonctionnalité bancaire.À l'époque, les acteurs évalués par Proofpoint utilisaient les variantes modifiées pour pivoter les logiciels malveillants loin de l'activité de Troie bancaire et de la fraude bancaire typique pour se concentrer sur la livraison de la charge utile, ce qui comprend probablement la hiérarchisation des ransomwares. TA571 utilise régulièrement 404 TD dans des campagnes pour fournir des logiciels malveillants, notamment Asyncrat, Netsupport et Darkgate.Les chercheurs de ProofPoint suivent 404 TDS depuis au moins septembre 2022, et il est utilisé par un certain nombre d'acteurs de menace.Un système de distribution de trafic (TDS) est une application utilisée pour acheminer le trafic Web via des serveurs contrôlés par l'opérateur.Ils peuvent être utilisés par les acteurs de la menace pour rediriger le trafic vers des téléchargements de logiciels malveillants et utiliser le filtrage IP pour déterminer s'il faut livrer une charge utile ou rediriger vers un site Web de récolte d'identification.ProofPoint évalue 404 TDS est probablement partagé ou vendu à d'autres acteurs en raison de son implication dans une variété de campagnes de phishing et de logiciels malveillantes sans rapport. Attribution TA571 est un distributeur de spam, et cet acteur envoie des campagnes de courriel de spam à volume élevé pour livrer et installer un logiciel malveillant variété pour leurs clients cybercriminaux, selon les objectifs de l'opérateur ultérieur.ProofPoint évalue avec une grande confiance que les infections à TA571 peuvent conduire à des ransomwares. Pourquoi est-ce important La livraison de Ta571 \\ de la variante iceide fourchue est unique car le point de preuve ne les observe pas souvent dans les données de menace.De plus, Proofpoint considère TA571 comme un acteur sophistiqué de menace cybercriminale.Sa chaîne d'attaque comprend un filtrage unique utilisant des «portes» intermédiaires pour que le trafic passe.Ces portes, qui sont des URL intermédiaires, filtrent le trafic basé sur la propriété intellectuelle et la géo-clôture.TA571 peut avoir jusqu'à deux portes par campagne.Il s'agit de garantir que seuls les utilisateurs spécifiquement ciblés reçoivent les logiciels malveillants et contourner l'activité automatisée de sable ou le chercheur.

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.

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 | ★★★ | |

The following is an excerpt from the Ransomware Survival Guide, our free handbook on preventing, managing and recovering from ransomware threats at every stage of the attack chain. This blog post provides general tips-it is not a substitute for professional cybersecurity and incident response services. The best ransomware strategy is to avoid it in the first place. But increasingly advanced attacks against the software supply chain and end users have shown that even the best-prepared companies can be caught out. Ransomware may not even be the first malware payload to infect your system, because many ransomware gangs now prefer to buy access to targets already infected with Trojans or loader malware. During an attack, you have short-term problems to resolve, like getting computers, phones and networks back online and dealing with ransom demands. But a panicked response won\'t help-and may make things worse. Here are some general steps you can take to contain the threat and start on the road to recovery. Questions to answer during a ransomware attack Before you react to an attack, it\'s important to take a step back and ask questions that will inform your response. Your answers should help network administrators scope the problem, devise an action plan and possibly curtail the spread. Who in your environment is compromised? How widespread are the infections? Is a threat actor actively scouting your environment, exfiltrating data or ready to drop ransomware on other devices? What network permissions do compromised accounts or devices have? Ransomware may have been installed only after attackers had already moved laterally within the network or stolen credentials and other data. What type of attack is it? Is this attack a secondary infection? Did it come from downloaders, remote access Trojans (RATs) or other malware installed on the infected machine or others on the network? Keep in mind that ransomware spreads quickly and is often a byproduct of other threats. If you see one infection, there are probably others that you don\'t see. Proactively look for other issues within your environment. Now as you take action, there are three general step to follow: Step 1: Isolate infected systems The second employees see the ransomware demand or notice something\'s odd-such as suddenly losing access to their own files-they should disconnect from the network and take the infected machine to the IT department. To prepare for this scenario, we recommend that you keep valuable data and systems separated so that a security issue on one system doesn\'t affect other systems. For example, your sensitive research or business data should not reside on the same server and network segment as your email environment. We advise against having employees reboot their system. Only the IT security team should attempt a reboot, and even that will work only in the event that it is “scareware,” or fake ransomware. "Scareware" is malware that appears to be ransomware but isn\'t. It may lock the user\'s screen with a ransom demand and payment instructions, but the data is not actually encrypted. In those scenarios, standard anti-malware tools can help. Knowing the difference isn\'t always easy. Determine the scope of the problem using threat intelligence and external incident responders or forensic analysts when necessary. While all ransomware is bad, some attacks are worse than others. Your response-including whether to pay the ransom-hinges on several factors. Step 2: Call law enforcement Ransomware-like other forms of theft and extortion-is a crime. Nobody has the right to seize devices, networks or data-let alone demand a ransom in exchange for it. Notifying the proper authorities is a necessary first step. Contact local or federal law enforcement right away. Special departments exist specifically to aid cyber crime victims, so do not be afraid to pick up your phone and call them. They are there to help you and may have access to decryption keys or information on payment recovery after | Ransomware Malware Tool Threat | ★★★ | |

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.

Welcome to the first installment of a three-part blog series that is focused on how to inspire engagement in security awareness for both users and practitioners. It will also explore creative techniques you can use to build a security culture that go beyond traditional security awareness training. Cybersecurity Awareness Month is an excellent time to rejuvenate your security awareness program. But how can you sustain the momentum of Cybersecurity Awareness Month beyond October? Try adding threat intelligence to your program. It can personalize and invigorate your curriculum for your users. Integrating threat intelligence into security awareness seems intuitive-and many practitioners claim to do it. But data suggests otherwise. Research Proofpoint conducted for our 2023 State of the Phish report found that while 75% of businesses faced business email compromise (BEC) attacks, a mere 31% trained their users about this threat. This indicates that while many businesses are aware of emerging threats, they struggle to weave this information into their training modules. This blog post delves into best practices for using threat intelligence to raise security awareness with users. It includes insights from a customer session we held during Proofpoint Wisdom 2023 entitled “Utilizing Threat Intel to Design a Program that Works.” During that session, I spoke with Andrew Munson, senior manager of information risk management and governance at McDonald\'s Corporation, and Shaun Holmberg, IT security analyst at Commercial Metals Corporation. Both provided insights into how they infuse threat intelligence into their global security awareness initiatives. Understanding threat intelligence Threat intelligence is the knowledge and analysis of cyber threats and vulnerabilities that can pose a risk to a business. This information includes details about the attack lifecycle, network architecture vulnerabilities and which users are being targeted. The intel should also provide details of the risk level or the consequential impact that a successful cyber attack may have on a business. This information can be gathered from various sources. According to Shaun and Andrew, examples of optimal sources for intelligence are: Research reports. These resources include, but are not limited to: State of the Phish from Proofpoint Verizon\'s Data Breach Investigations Report (DBIR) FBI Internet Crime Report (Internet Crime Complaint Center) Coalition\'s Cyber Claims Report Security feeds. Proofpoint threat intelligence services, Rapid7 and Cyber Reasons are examples of providers of these feeds. Incident reports from products. These reports include Proofpoint Targeted Attack Protection reports, Proofpoint Closed Loop Email Analysis (CLEAR) and other reports related to the penetration testing of a company\'s infrastructure. Why is threat intelligence crucial for a security awareness program? Let\'s dive deeper into this subject using insights from the recent discussion with Andrew and Shaun. Making threat intelligence actionable At McDonald\'s, Andrew works with departments across the globe. Each region has its own requirements and is targeted with threats specific to an office. This is where working with a resource like the Proofpoint threat intelligence service team can create significant benefits for security teams. Andrew described how working with our team gives him an advantage. He said the Proofpoint threat intelligence service team can analyze data across the globe to correlate attacks that may be affecting a single region. For example, they can recognize a targeted attack specific to Germany, which differs from an active attack they\'ve identified targeting Austria. Andrew said he uses this data to build separate simulations that mimic the active attack for each region and launches an auto-enrollment training session tuned to recognizing the attack indicators. He can also provide resources like notifications or informative newsletters, all within the region\'s native l | Ransomware Data Breach Vulnerability Threat Studies | ★★ | |

2023-10-06 05:00:34 | 7 meilleures pratiques pour la sécurité active de la répertoire pour empêcher les attaquants de sortir 7 Best Practices for Active Directory Security to Keep Attackers Out (lien direct) |
Active Directory security is a top-of-mind and ongoing concern for countless cybersecurity teams. Why? Because attackers are relentless in their efforts to target this vital directory service and identity management hub for Microsoft Windows-based networks. If a bad actor infiltrates a company\'s Active Directory (AD) they can work to escalate their privileges, move laterally through the network and gain access to sensitive data and systems. There are multiple ways to fortify your Active Directory security. In this post, we\'ll look at seven examples of Active Directory security best practices that can help you reduce the risk of costly breaches. These best practices make it tougher for bad actors to gain access to your AD in the first place. First, let\'s take closer look at Active Directory and its purpose. Then, we\'ll explain why Active Directory security is important and describe some common risks associated with it. What is Active Directory? Microsoft introduced Active Directory nearly a quarter-century ago. Today, it is a crucial component of Windows-based networks for businesses around the globe. AD plays a central role in how resources are managed and organized within a networked environment. AD stores information about objects on a network-like a printer, application or a user\'s account-and makes it easy for network administrators and users to locate and use that information. AD also manages user identities, authentication and access permissions. Active Directory allows administrators to enforce security policies, set password policies and control access to sensitive systems and data. So, for example, if you want to check your email or access the internet via your company\'s Windows-based network, AD is what permits you to connect to those resources. It also facilitates the single sign-on (SSO) authentication process. Why is Active Directory security so important? As noted at the top of this post, if a bad actor can compromise Active Directory, they are well on their way toward gaining access to sensitive data-or doing something worse. Here are just a few reasons that AD environments are prime targets for attackers: Centralized control. Active Directory is a central point of control for network resources including user accounts and servers. Once inside AD, attackers can take control of your entire network and potentially compromise other resources connected to it. Credential theft. Attackers can steal usernames and passwords stored in your AD. They can then use those credentials to access other systems, apps and data within your company. Privilege escalation. Active Directory stores information about user roles, permissions and group memberships. So, if an attacker can escalate their privileges within AD, they can gain access to other systems or admin accounts. That will allow them to make lateral moves within the network and expand their foothold. Persistence. Once attackers are inside Active Directory, they can establish persistence within the network. They can set up backdoor access, add rogue user accounts or manipulate security policies-moves designed to make it easier for them to evade detection. And if they are discovered, it will be harder for security teams to remove them from the network because they will have already created multiple other points of entry. What are some common Active Directory security risks? By now, it is probably clear that two of the most significant Active Directory security risks are unauthorized access to accounts and systems and the theft of credentials like usernames and passwords. The latter is, of course, a vital strategy for gaining unauthorized access. As your business works to improve Active Directory security, you will want to address common risks like these sooner than later: Inadequate password policies. Strong passwords are essential to prevent data breaches and data loss. If your password practices and policies are lacking, you can be sure that attackers will take full advantage of those weaknesses. To | Ransomware Vulnerability Threat | ★★ | |

2023-09-27 05:00:29 | Une perspective CISO sur les menaces d'identité A CISO Perspective on Identity Threats (lien direct) |
Compromised credentials and commandeered accounts can act as skeleton keys for your networks and corporate systems. With such a potentially lucrative reward on offer, cyber criminals are increasingly focusing their attacks on your identities to unleash data exfiltration, take over IT environments and launch ransomware attacks. To gain a deeper understanding of how industry leaders are tackling this shift in the threat landscape, I recently participated in a webinar led by Proofpoint executives Tim Choi, group vice president of product marketing, and Ofer Israeli, group vice president and general manager, Identity Threat Defense. We discussed why identity attacks are a growing problem, the challenges of identifying vulnerable users, and how to protect people and data from attacks that use compromised accounts. The ease that compromised identities offer Our industry uses the term “people-centric” a lot. We know that attackers target people so they can launch ransomware campaigns or exfiltrate data. But for today\'s cyber criminals, that is no longer the end of the matter. Threat actors now target people to compromise identities. They use those identities to further elevate their access and privileges. And they, they make lateral moves within organizations to gain intel, launch further attacks and steal more data. Thanks to tools like Mimikatz and Bloodhound that can identify hidden relationships, user permissions and attack paths, the whole process of targeting identities, stealing credentials and escalating privileges is now very simple. Understanding high-risk identities Malicious actors need to know two things to increase the chances of a successful attack: where the data is that they want, and which identity will give them access to it. Most of the time, the answer to the latter is a service account. These accounts are not always protected in a privileged access management solution. They often have access to many different files and systems with static passwords that can do nothing. Regular users who are shadow administrators are also very high-risk identities. They\'re not usually marked as privileged but have often inherited all kinds of access through complicated Active Directory group memberships, which are very hard to follow. Where are organizations most vulnerable to identity attacks? Most organizations have struggled with identity and access management (IAM) for many years. Access has a way of becoming a living, breathing organism, so security teams need to make sure they understand what\'s going on with it. There are three main areas of concern: Shared credentials Stored credentials Shared secrets Most users will have tens, if not hundreds, of usernames and passwords across various accounts. And they are likely reusing credentials across at least some of them. All it takes is for just one site to suffer an attack, and those credentials can be sprayed across many more accounts and systems. When it comes to password storage, businesses must be extremely careful. Get them out of the environment they are used in as a starting point. Unfortunately, many identity attacks originate from drive-by hacking, where cyber criminals get credentials from password dumps or data breaches and try their luck, password spraying across corporate accounts. Protecting your identities Cybersecurity is like an asynchronous war. And by the time we\'ve built a new control or defense mechanism, the bad guys have figured out a new way to circumvent it. That is what\'s happening right now. There are plenty of statistics to confirm that even in the largest breaches, threat actors get in right through the front door. How? Because they gain access to a shared credential and identity that has more access than anyone at the target organization was aware it had. Fundamentally, it is a hygiene issue. We\'re all guilty of getting caught up in new, fancy rocket-science security capabilities. But we\'re missing some of the basics. That\'s simp | Ransomware Tool Threat | ★★★ | |

Si vous avez lu notre guide de survie à Ransomware mis à jour, vous savez déjà que le ransomware moderne est rarement livré directement par e-mail.De nos jours, les gangs de ransomware préfèrent s'associer avec les courtiers d'accès initiaux (IAB).Les IAB fonctionnent en distribuant des logiciels malveillants dans des campagnes à haut volume, puis en vendant un accès à des systèmes compromis.Mais il y a encore des cas de bord où les acteurs de la menace essaient de couper l'intermédiaire et de livrer directement des ransomwares.
Un exemple récent de ceci est Knight ou Knight Lite Ransomware (une version rebaptisée du cyclops ransomware-as-a-Service).En août 2023, les chercheurs de Proofpoint ont vu plusieurs campagnes dans lesquelles Knight a été livré directement par e-mail.Ces campagnes étaient principalement à faible volume, avec moins de 500 messages, bien qu'une campagne en contenait plus de 1 000.Les campagnes ont principalement ciblé les utilisateurs anglophones, mais nous avons également noté des campagnes ciblant les utilisateurs en Italie et en Allemagne dans ces langues.
Un leurre sur le thème de la facture a envoyé une récente campagne Knight.
Les leurres e-mail de ces campagnes ont inclus des faux messages d'un site Web de voyage bien connu destiné aux organisations hôtelières, ainsi qu'à des leurres de facturation plus standard.Les e-mails contiennent une pièce jointe HTML qui charge une interface de navigateur dans le navigateur usurpant le site légitime.Cette interface invite ensuite la victime à cliquer et à télécharger un fichier exécutable ou xll zippé contenant le ransomware.Dans certaines campagnes ultérieures ciblant les utilisateurs italiens, la chaîne d'attaque a été modifiée pour inclure un fichier zip interstitiel contenant soit un LNK reliant à un partage WebDAV ou à un XLL, qui installent tous deux un téléchargeur.Cela installe à son tour la charge utile Knight.Le téléchargeur utilisé dans ces chaînes d'attaque ultérieurs n'a pas été vu auparavant dans nos données, et nos chercheurs enquêtent.Dans toutes les chaînes d'attaque, une fois installées, Knight Ransomware commence un mouvement latéral, en scrutant des adresses IP privées en tant que précurseur pour chiffrer les appareils en réseau.
Les fichiers sont chiffrés par une extension .Knight_L, et une note de rançon est laissée des sommes exigeantes allant de 5 000 $ à 15 000 $ en Bitcoin.L'acteur de menace fournit un lien vers un site contenant des instructions supplémentaires et une adresse e-mail pour les informer lorsqu'un paiement a été effectué.Actuellement, il n'y a rien pour indiquer que les données sont exfiltrées et chiffrées.

2023-09-19 05:00:12 | Pourquoi les données sur les soins de santé sont difficiles à protéger et quoi faire à ce sujet Why Healthcare Data Is Difficult to Protect-and What to Do About It (lien direct) |
Hospitals, clinics, health insurance providers and biotech firms have long been targets for cyber criminals. They handle data like protected health information (PHI), intellectual property (IP), clinical trial data and payment card data, giving attackers many options to cash in. And as healthcare institutions embrace the cloud, remote work and telehealth, the risks of attacks on this data only increase. Besides outside attackers, insider risk is another concern in an industry where employees face high and sustained levels of stress. And then there\'s the increasing risk of ransomware. In the 2022 Internet Crime Report from the FBI\'s Internet Crime Complaint Center, healthcare was called out as the critical infrastructure industry hardest hit by ransomware attacks. In this blog, we\'ll take a look at some of the information protection challenges faced by the healthcare industry today. And we\'ll look at some solutions. Healthcare data breach costs Not only are data breaches in healthcare on the rise, but the costs for these breaches are high for this industry, too. IBM\'s Cost of a Data Breach Report 2023 says that the average cost of a healthcare data breach in the past year was $11 million. These costs can include: Ransoms paid Systems remediation Noncompliance fines Litigation Brand degradation There\'s a high cost in terms of disruptions to patient care as well. System downtime or compromised data integrity due to cyber attacks can put patients at risk. For example, when Prospect Medical Holdings faced a recent cyber attack, its hospitals had to shut down their IT networks to prevent the attack\'s spread. They also needed to revert to paper charts. The Rhysida ransomware gang claimed responsibility for that attack, where a wealth of data, including 500,000 Social Security numbers, patient files, and legal documents, was stolen. Information protection challenges in healthcare Healthcare firms face many challenges in protecting sensitive data. They include: Insider threats and electronic health record (EHR) snooping What are some insider threats that can lead to data breaches in healthcare? Here\'s a short list of examples: Employees might sneak a peek at the medical records of a famous patient and share the details with the media. Careless workers could click on phishing emails and open the door to data theft. Malicious insiders can sell patient data on the dark web. Departing employees can take valuable research data with them to help along own careers. A growing attack surface due to cloud adoption Most healthcare businesses are increasing their use of cloud services. This move is helping them to improve patient care by making information more accessible. But broad sharing of files in cloud-based collaboration platforms increases the risk of a healthcare data breach. It is a significant risk, too. Proofpoint threat intelligence shows that in 2022, 62% of all businesses were compromised via cloud account takeover. Data at risk across multiple data loss channels When EHRs are housed on-premises, patient records can still be accessed, shared and stored on remote endpoint and cloud-based collaboration and email systems. And as healthcare data travels across larger geographies, protecting it becomes much more of a challenge. How Proofpoint can help Our information protection platform, Proofpoint Sigma, provides unmatched visibility and control over sensitive data across email, cloud, web and endpoints. This unified platform allows healthcare businesses to manage data risk, while saving time and reducing operational costs. We can help protect your data from accidental disclosure, malicious attacks and insider risk.

Microsoft 365 has become the de facto standard for email and collaboration for most global businesses. At the same time, email continues to be the most common attack vector for threat actors. And spam, phishing, malware, ransomware and business email compromise (BEC) attacks keep increasing in both their sophistication and impact. Verizon\'s 2023 Data Breach Investigations Report highlights the upward trend BEC attacks, noting that they have doubled over the past year and comprise 60% of social engineering incidents. While Microsoft 365 includes basic email hygiene capabilities with Exchange Online Protection (EOP), you need more capabilities to protect your business against these attacks. Microsoft offers Defender for Office 365 (MDO) as part of its security tool set to bolster security. And it\'s a good place to start, but it simply can\'t stop today\'s most sophisticated email threats. That\'s why analysts suggest you augment native Microsoft 365 security to protect against advanced threats, like BEC and payload-less attacks such as TOAD (telephone-oriented attack delivery). “Supplement the native capabilities of your existing cloud email solutions with third-party security solutions to provide phishing protection for collaboration tools and to address both mobile- and BEC-type phishing scenarios.” Source: 2023 Gartner Market Guide for Email Security The rise of cloud-based email security solutions Email threats are nothing new. For years now, secure email gateways (SEG) have been the go-to solution to stop them. They filter spam, phishing emails and malware before they can get to users\' inboxes. But with more businesses adopting cloud-based email platforms-particularly Microsoft 365-alternative email security solutions have appeared on the market. Gartner calls them integrated cloud email security (ICES); Forrester refers to them as cloud-native API-enabled email security (CAPES). These solutions leave the basic email hygiene and handling of email traffic to Microsoft. Then, they examine the emails that are allowed through. Essentially, they identify threats that have slipped past Microsoft\'s defenses. The main advantage of ICES and CAPES is their ease of deployment and evaluation. They simply require a set of permissions to the Microsoft 365 installation, and they can start detecting threats right away. It\'s easy to remove these solutions, too, making it simple and straightforward to evaluate them. Two deployment models: the good and the bad When you\'re augmenting Microsoft 365 email security, you have several options for deployment. There\'s the post-delivery, API-based approach, which is used by ICES and CAPEs. And there\'s the pre-delivery, MX-based approach used by SEGs. Post-delivery deployment (API-based model) In this scenario, Microsoft provides an API to allow third-party vendors to receive a notification when a new email is delivered to a user\'s mailbox. Then, they process the message with their platform. If a threat is found, it can be deleted or moved to a different folder, like quarantine or junk. However, this approach presents a risk. Because a message is initially delivered to the mailbox, a user still has a chance to click on it until the threat is retracted. Emails must be processed fast or hidden altogether while the solution scans the message for threats. Analyzing attachments for malware or running them through a sandbox is time-consuming, especially for large or complex attachments. There are also limits on how many alerts from Microsoft 365 that cloud-based email security solutions can receive. Pre-delivery deployment (MX-based model) This approach is useful for businesses that want to detect and prevent email threats before they reach their users\' inboxes. As the name suggests, email is processed before it is delivered to a user\'s inbox. To enable this model, an organization\'s DNS email exchange (MX) record must be configured to a mail server.
