## Instantané Symantec a identifié une augmentation des cyberattaques utilisant des modèles de grande langue (LLM) pour générer du code malveillant pour télécharger diverses charges utiles. En savoir plus sur la façon dont Microsoft s'est associé à OpenAI pour [rester en avance sur les acteurs de la menace à l'ère de l'IA] (https://security.microsoft.com/intel-explorer/articles/ed40fbef). ## Description Les LLM, conçues pour comprendre et créer du texte de type humain, ont des applications, de l'assistance à l'écriture à l'automatisation du service client, mais peuvent également être exploitées à des fins malveillantes.Les campagnes récentes impliquent des e-mails de phishing avec du code pour télécharger des logiciels malveillants comme Rhadamanthys, Netsupport et Lokibot.Ces attaques utilisent généralement des scripts PowerShell générés par LLM livrés via des fichiers .lnk malveillants dans des fichiers zip protégés par mot de passe.Un exemple d'attaque impliquait un e-mail de financement urgent avec un tel fichier zip, contenant des scripts probablement générés par un LLM.Les recherches de Symantec \\ ont confirmé que les LLM comme Chatgpt peuvent facilement produire des scripts similaires.La chaîne d'attaque comprend l'accès initial via des e-mails de phishing, l'exécution des scripts générés par LLM et le téléchargement final de la charge utile.Symantec met en évidence la sophistication croissante des attaques facilitées par l'IA, soulignant la nécessité de capacités de détection avancées et de surveillance continue pour se protéger contre ces menaces en évolution. ## Analyse Microsoft Microsoft a identifié des acteurs comme [Forest Blizzard] (https://security.microsoft.com/Intel-Profiles / DD75F93B2A771C9510DCEEC817B9D34D868C2D1353D08C8C1647DE067270FDF8), [EMERDD Sleet] (HTTP EE4ED596D8AE16F942F442B895752AD9F41DD58E), [Crimson Sandstorm] (https://sip.security.microsoft.com/intel-profiles/34E4ACFE2868D450AC93C5C3E6D2DF021E2801BDB3700DD8F172D602DF6DA046), [CHARCOAL TYPHOON] ( 3DB3D52D0495410EFD39D506AAD9A4) et [Typhoon de saumon] (https://security.microsoft.com/intel-profiles/5323e9969bf361e48bc236a53189 6) Tirer parti des LLMautomatiseret optimiser la génération de scripts;Cependant, certains de ces acteurs ont exploité les LLM de d'autres manières, notamment la reconnaissance, la recherche sur la vulnérabilité, l'ingénierie sociale et la traduction des langues.En savoir plus sur la façon dont ces acteurs interagissent et utilisent les LLM sur le [Microsoft Security Blog] (https://www.microsoft.com/en-us/security/blog/2024/02/14/staying-ahead-of--of-Les acteurs de la menace à l'âge-ai /). ## Détections / requêtes de chasse Microsoft Defender Antivirus détecte les composants de la menace comme le malware suivant: - [* Trojan: Msil / Lazy *] (https: // www.Microsoft.com/en-us/wdsi/therets/malware-encyclopedia-dercription?name=trojan:mil/lazy.beaa!mtb) - [* Trojan: Win32 / Oyster *] (https://www.microsoft.com/en-us/wdsi/therets/malware-encycopedia-dercription?name=trojan:win32/oyster!mtb) - [* Trojan: JS / Nemucod!

2024-03-05 19:03:47 | Rester en avance sur les acteurs de la menace à l'ère de l'IA Staying ahead of threat actors in the age of AI (lien direct) |
## Snapshot Over the last year, the speed, scale, and sophistication of attacks has increased alongside the rapid development and adoption of AI. Defenders are only beginning to recognize and apply the power of generative AI to shift the cybersecurity balance in their favor and keep ahead of adversaries. At the same time, it is also important for us to understand how AI can be potentially misused in the hands of threat actors. In collaboration with OpenAI, today we are publishing research on emerging threats in the age of AI, focusing on identified activity associated with known threat actors, including prompt-injections, attempted misuse of large language models (LLM), and fraud. Our analysis of the current use of LLM technology by threat actors revealed behaviors consistent with attackers using AI as another productivity tool on the offensive landscape. You can read OpenAI\'s blog on the research [here](https://openai.com/blog/disrupting-malicious-uses-of-ai-by-state-affiliated-threat-actors). Microsoft and OpenAI have not yet observed particularly novel or unique AI-enabled attack or abuse techniques resulting from threat actors\' usage of AI. However, Microsoft and our partners continue to study this landscape closely. The objective of Microsoft\'s partnership with OpenAI, including the release of this research, is to ensure the safe and responsible use of AI technologies like ChatGPT, upholding the highest standards of ethical application to protect the community from potential misuse. As part of this commitment, we have taken measures to disrupt assets and accounts associated with threat actors, improve the protection of OpenAI LLM technology and users from attack or abuse, and shape the guardrails and safety mechanisms around our models. In addition, we are also deeply committed to using generative AI to disrupt threat actors and leverage the power of new tools, including [Microsoft Copilot for Security](https://www.microsoft.com/security/business/ai-machine-learning/microsoft-security-copilot), to elevate defenders everywhere. ## Activity Overview ### **A principled approach to detecting and blocking threat actors** The progress of technology creates a demand for strong cybersecurity and safety measures. For example, the White House\'s Executive Order on AI requires rigorous safety testing and government supervision for AI systems that have major impacts on national and economic security or public health and safety. Our actions enhancing the safeguards of our AI models and partnering with our ecosystem on the safe creation, implementation, and use of these models align with the Executive Order\'s request for comprehensive AI safety and security standards. In line with Microsoft\'s leadership across AI and cybersecurity, today we are announcing principles shaping Microsoft\'s policy and actions mitigating the risks associated with the use of our AI tools and APIs by nation-state advanced persistent threats (APTs), advanced persistent manipulators (APMs), and cybercriminal syndicates we track. These principles include: - **Identification and action against malicious threat actors\' use:** Upon detection of the use of any Microsoft AI application programming interfaces (APIs), services, or systems by an identified malicious threat actor, including nation-state APT or APM, or the cybercrime syndicates we track, Microsoft will take appropriate action to disrupt their activities, such as disabling the accounts used, terminating services, or limiting access to resources. - **Notification to other AI service providers:** When we detect a threat actor\'s use of another service provider\'s AI, AI APIs, services, and/or systems, Microsoft will promptly notify the service provider and share relevant data. This enables the service provider to independently verify our findings and take action in accordance with their own policies. - **Collaboration with other stakeholders:** Microsoft will collaborate with other stakeholders to regularly exchange information a | Ransomware Malware Tool Vulnerability Threat Studies Medical Technical | APT 28 ChatGPT APT 4 | ★★ |
