2023-09-20 05:00:47 | Toutes les vulnérabilités ne sont pas créées égales: les risques d'identité et les menaces sont la nouvelle vulnérabilité Not All Vulnerabilities Are Created Equal: Identity Risks and Threats Are the New Vulnerability (lien direct) |
If the history of cyber threats has taught us anything, it\'s that the game is always changing. The bad actors show us a move. We counter the move. Then, the bad actors show us a new one. Today, that “new move” is the vulnerable state of identities. Attackers realize that even if the network and every endpoint and device are secured, they can still compromise an enterprise\'s resources by gaining access to one privileged account. There is a lot of opportunity to do that, too. Within companies, one in six endpoints has an exploitable identity risk, as research for the Analyzing Identity Risks (AIR) Research Report from Proofpoint found. “Well, that escalated quickly.” The latest Data Breach Investigations Report from Verizon highlights the risks of complex attacks that involve system intrusion. It also underscores the need to disrupt the attacker once they are inside your environment. Once they have that access, they will look for ways to escalate privileges and maintain persistence. And they will search for paths that will allow them to move across the business so that they can achieve their goals, whatever they may be.hey may be. This problem is getting worse because managing enterprise identities and the systems to secure them is complex. Another complication is the constant changes to accounts and their configurations. Attackers are becoming more focused on privileged identity account takeover (ATO) attacks, which allow them to compromise businesses with ease and speed. At least, as compared with the time, effort and cost that may be required to exploit a software vulnerability (a common vulnerability and exposure or CVE). We should expect this trend to continue, given that ATOs have reduced attacker dwell times from months to days. And there is little risk that attackers will be detected before they are able to complete their crimes. How can IT and security leaders and their teams respond? A “back to the basics” approach can help. Shifting the focus to identity protection Security teams work to protect their networks, systems and endpoints in their infrastructure, and they have continued moving up the stack to secure applications. Now, we need to focus more on ways to improve how we protect identities. That is why an identity threat detection and response (ITDR) strategy is so essential today. We tend to think of security in battle terms; as such, identity is the next “hill” we need to defend. As we have done with the network, endpoint and application hills in the past, we should apply basic cyber hygiene and security posture practices to help prevent identity risk. There is value in using preventative and detective controls in this effort, but the former type of control is preferred. (It can cost less to deploy, too.) In other words, as we take this next hill to secure identity threats, we should keep in mind that an ounce of prevention is worth a pound of cure. Identity as a vulnerability management asset type Businesses should consider managing remediation of the identity vulnerabilities that are most often attacked in the same or a similar way to how they manage the millions of other vulnerabilities across their other asset types (network, host, application, etc.). We need to treat identity risk as an asset type. Its vulnerability management should be included in the process for prioritizing vulnerabilities that need remediation. A requirement for doing this is the ability to scan the environment on a continuous basis to discover identities that are vulnerable now-and learn why are at risk. Proofpoint SpotlightTM provides a solution. It enables: The continuous discovery of identity threats and vulnerability management Their automated prioritization based on the risk they pose Visibility into the context of each vulnerability And Spotlight enables fully automated remediation of vulnerabilities where the remediation creates no risk of business interruption.

2023-09-20 05:00:00 | Les logiciels malveillants chinois apparaissent sérieusement dans le paysage des menaces de cybercriminalité Chinese Malware Appears in Earnest Across Cybercrime Threat Landscape (lien direct) |
Key Takeaways Proofpoint has observed an increase in activity from specific malware families targeting Chinese-language speakers. Campaigns include Chinese-language lures and malware typically associated with Chinese cybercrime activity. Newly observed ValleyRAT is emerging as a new malware among Chinese-themed cybercrime activity, while Sainbox RAT and related variants are recently active as well. The increase in Chinese language malware activity indicates an expansion of the Chinese malware ecosystem, either through increased availability or ease of access to payloads and target lists, as well as potentially increased activity by Chinese speaking cybercrime operators. Overview Since early 2023, Proofpoint observed an increase in the email distribution of malware associated with suspected Chinese cybercrime activity. This includes the attempted delivery of the Sainbox Remote Access Trojan (RAT) – a variant of the commodity trojan Gh0stRAT – and the newly identified ValleyRAT malware. After years of this malware not appearing in Proofpoint threat data, its appearance in multiple campaigns over the last six months is notable. The phrase “Chinese-themed” is used to describe any of the observed content related to this malicious activity, including lures, malware, targeting, and any metadata that contains Chinese language usage. Campaigns are generally low-volume and are typically sent to global organizations with operations in China. The email subjects and content are usually written in Chinese, and are typically related to business themes like invoices, payments, and new products. The targeted users have Chinese-language names spelled with Chinese-language characters, or specific company email addresses that appear to align with businesses\' operations in China. Although most campaigns have targeted Chinese speaking users, Proofpoint observed one campaign targeting Japanese organizations, suggesting a potential expansion of activity. These recently identified activity clusters have demonstrated flexible delivery methods, leveraging both simple and moderately complex techniques. Commonly, the emails contain URLs linking to compressed executables that are responsible for installing the malware. However, Proofpoint has also observed Sainbox RAT and ValleyRAT delivered via Excel and PDF attachments containing URLs linking to compressed executables. Proofpoint researchers assess those multiple campaigns delivering Sainbox RAT and ValleyRAT contain some similar tactics, techniques, and procedures (TTPs). However, research into additional activity clusters utilizing these malwares demonstrate enough variety in infrastructure, sender domains, email content, targeting, and payloads that researchers currently conclude that all use of these malwares and associated campaigns are not attributable to the same cluster, but likely multiple distinct activity sets. The emergence and uptick of both novel and older Chinese-themed malware demonstrates a new trend in the overall 2023 threat landscape. A blend of historic malware such as Sainbox – a variant of the older Gh0stRAT malware – and the newly uncovered ValleyRAT may challenge the dominance that the Russian-speaking cybercrime market has on the threat landscape. However, the Chinese-themed malware is currently mostly targeted toward users that likely speak Chinese. Proofpoint continues to monitor for evidence of increasing adoption across other languages. For network defenders, we include several indicators of compromise and Emerging Threats detections to provide the community with the ability to cover these threats. Campaign Details Proofpoint has observed over 30 campaigns in 2023 leveraging malware typically associated with Chinese cybercrime activity. Nearly all lures are in Chinese, although Proofpoint has also observed messages in Japanese targeting organizations in that country.

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.

2023-09-18 05:00:09 | Comment mieux sécuriser et protéger votre environnement Microsoft 365 How to Better Secure and Protect Your Microsoft 365 Environment (lien direct) |
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. The MX record indicates how email messages should be routed in | Ransomware Data Breach Malware Tool Threat Prediction Cloud | ★★★ | |

2023-09-15 09:50:31 | L'avenir de l'autonomisation de la conscience de la cybersécurité: 5 cas d'utilisation pour une IA générative pour augmenter votre programme The Future of Empowering Cybersecurity Awareness: 5 Use Cases for Generative AI to Boost Your Program (lien direct) |
Social engineering threats are increasingly difficult to distinguish from real media. What\'s worse, they can be released with great speed and at scale. That\'s because attackers can now use new forms of artificial intelligence (AI), like generative AI, to create convincing impostor articles, images, videos and audio. They can also create compelling phishing emails, as well as believable spoof browser pages and deepfake videos. These well-crafted attacks developed with generative AI are creating new security risks. They can penetrate protective defense layers by exploiting human vulnerabilities, like trust and emotional response. That\'s the buzz about generative AI. The good news is that the future is wide open to fight fire with fire. There are great possibilities for using a custom-built generative AI tool to help improve your company\'s cybersecurity awareness program. And in this post, we look at five ways your organization might do that, now or in the future. Let\'s imagine together how generative AI might help you to improve end users\' learning engagement and reduce human risk. 1. Get faster alerts about threats If your company\'s threat intelligence exposes a well-designed credential attack targeting employees, you need to be quick to alert and educate users and leadership about the threat. In the future, your company might bring in a generative AI tool that can deliver relevant warnings and alerts to your audiences faster. Generative AI applications can analyze huge amounts of data about emerging threats at greater speed and with more accuracy than traditional methods. Security awareness administrators might run queries such as: “Analyze internal credential phishing attacks for the past two weeks” “List BEC attacks for credentials targeting companies like mine right now” In just a few minutes, the tool could summarize current credential compromise threats and the specific “tells” to look for. You could then ask your generative AI tool to create actionable reporting about that threat data on the fly, which saves time because you\'re not setting up dashboards. Then, you use the tool to push out threat alerts to the business. It could also produce standard communications like email messages and social channel notifications. You might engage people further by using generative AI to create an eye-catching infographic or a short, animated video in just seconds or minutes. No need to wait days or weeks for a designer to produce that visual content. 2. Design awareness campaigns more nimbly Say that your security awareness team is planning a campaign to teach employees how to spot attacks targeting their credentials, as AI makes phishing emails more difficult to spot. Your security awareness platform or learning management system (LMS) has a huge library of content you can tap for this effort-but your team is already overworked. In the future, you might adapt a generative AI tool to reduce the manual workload by finding what information is most relevant and providing suggestions for how to use it. A generative AI application could scan your content library for training modules and awareness materials. For instance, an administrator could make queries such as: “Sort existing articles for the three biggest risks of credential theft” “Suggest training assignments that educate about document attachments” By applying this generative AI use case to searching and filtering, you would shortcut the long and tedious process of looking for material, reading each piece for context, choosing the most relevant content, and deciding how to organize what you\'ve selected. You could also ask the generative AI tool to recommend critical topics missing in the available content. The AI might even produce the basis for a tailored and personalized security campaign to help keep your people engaged. For instance, you could ask the tool to sort content based on nonstandard factors you consider interesting, such as mentioning a geographic region or holiday season. 3.
