This blog post is part of a monthly series, Cybersecurity Stop of the Month, which explores the ever-evolving tactics of today\'s cybercriminals. It focuses on the critical first three steps in the attack chain in the context of email threats. The goal of this series is to help you understand how to fortify your defenses to protect people and defend data against emerging threats in today\'s dynamic threat landscape. The critical first three steps of the attack chain-reconnaissance, initial compromise and persistence. So far in this series, we have examined these types of attacks: Supplier compromise EvilProxy SocGholish eSignature phishing QR code phishing Telephone-oriented attack delivery (TOAD) Payroll diversion MFA manipulation Supply chain compromise Multilayered malicious QR code attack In this post, we will look at how adversaries use impersonation via BEC to target the manufacturing supply chain. Background BEC attacks are sophisticated schemes that exploit human vulnerabilities and technological weaknesses. A bad actor will take the time to meticulously craft an email that appears to come from a trusted source, like a supervisor or a supplier. They aim to manipulate the email recipient into doing something that serves the attacker\'s interests. It\'s an effective tactic, too. The latest FBI Internet Crime Report notes that losses from BEC attacks exceeded $2.9 billion in 2023. Manufacturers are prime targets for cybercriminals for these reasons: Valuable intellectual property. The theft of patents, trade secrets and proprietary processes can be lucrative. Complex supply chains. Attackers who impersonate suppliers can easily exploit the interconnected nature of supply chains. Operational disruption. Disruption can cause a lot of damage. Attackers can use it for ransom demands, too. Financial fraud. Threat actors will try to manipulate these transactions so that they can commit financial fraud. They may attempt to alter bank routing information as part of their scheme, for example. The scenario Proofpoint recently caught a threat actor impersonating a legitimate supplier of a leading manufacturer of sustainable fiber-based packaging products. Having compromised the supplier\'s account, the imposter sent an email providing the manufacturer with new banking details, asking that payment for an invoice be sent to a different bank account. If the manufacturer had complied with the request, the funds would have been stolen. The threat: How did the attack happen? Here is a closer look at how the attack unfolded: 1. The initial message. A legitimate supplier sent an initial outreach email from their account to the manufacturing company using an email address from their official account. The message included details about a real invoice that was pending payment. The initial email sent from the supplier. 2. The deceptive message. Unfortunately, subsequent messages were not sent from the supplier, but from a threat actor who was pretending to work there. While this next message also came from the supplier\'s account, the account had been compromised by an attacker. This deceptive email included an attachment that included new bank payment routing information. Proofpoint detected and blocked this impersonation email. In an attempt to get a response, the threat actor sent a follow-up email using a lookalike domain that ended in “.cam” instead of “.com.” Proofpoint also condemned this message. An email the attacker sent to mimic the supplier used a lookalike domain. Detection: How did Proofpoint prevent this attack?

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 | ★★★ |

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 | ★★★ |

2023-09-15 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.
