#### Targeted Geolocations - Ukraine ## Snapshot The Computer Emergency Response Team of Ukraine (CERT-UA) released reporting on an attack by UAC-0063 against a research institution in Ukraine perpetrated in July 2024. ## Description The attackers accessed an employee\'s email account and sent a compromised email with a macro-embedded document to multiple recipients. When opened, this document created and executed another document and scheduled a task to run the HATVIBE malware. The attackers then used remote control to download a Python interpreter and the CHERRYSPY malware to the victim\'s computer. UAC-0063, linked to the Russian APT28 group, was also detected using a similar attack vector in Armenia. In June 2024, the group exploited a vulnerability in the HFS HTTP File Server ([CVE-2024-23692](https://security.microsoft.com/intel-explorer/cves/CVE-2024-23692/)) to install the HATVIBE backdoor, demonstrating their use of varied initial compromise methods. The attack succeeded due to the institution\'s lack of two-factor authentication, admin privileges for user accounts, and insufficient security policies to block macros and specific executables. ## Additional Analysis Both CHERRYSPY and HATVIBE have previously been used by UAC-0063 to target Ukranian organizations. [In April 2023](https://cert.gov.ua/article/4697016?fbclid=IwAR1B5gj0v-Ve9Q5299ydM5lrInLuKVmvPRosQkUucq6YzcjuTgVnM_x3LjQ), the threat group sent spear-phishing emails to government organizations in Ukraine, likely from the previously compromised email of the Embassy of Tajikistan. ## Recommendations Microsoft recommends the implementation multifactor authentication (MFA) to reduce the impact of this threat and mitigate credential theft from phishing attacks. MFA can be complemented with the following solutions and best practices to protect organizations: - Activate [conditional access](https://learn.microsoft.com/en-us/entra/identity/conditional-access/overview?ocid=magicti_ta_learndoc) policies. Conditional access policies are evaluated and enforced every time an attacker attempts to use a stolen session cookie. Organizations can protect themselves from attacks that leverage stolen credentials by activating policies regarding compliant devices or trusted IP address requirements. - Configure [continuous access evaluation](https://learn.microsoft.com/en-us/entra/identity/conditional-access/concept-continuous-access-evaluation?ocid=magicti_ta_learndoc) in your tenant. - Invest in advanced anti-phishing solutions that monitor incoming emails and visited websites. [Microsoft Defender for Office 365](https://learn.microsoft.com/en-us/defender-xdr/microsoft-365-security-center-mdo?ocid=magicti_ta_learndoc) brings together incident and alert management across email, devices, and identities, centralizing investigations for threats in email. Organizations can also leverage web browsers that automatically identify and block malicious websites, including those used in this phishing campaign. To build resilience against phishing attacks in general, organizations can use [anti-phishing policies](https://learn.microsoft.com/en-us/defender-office-365/anti-phishing-policies-about?view=o365-worldwide) to enable mailbox intelligence settings, as well as configure impersonation protection settings for specific messages and sender domains. Enabling [SafeLinks](https://learn.microsoft.com/en-us/defender-office-365/safe-links-about?view=o365-worldwide) ensures real-time protection by scanning at time of delivery and at time of click. - Monitor for suspicious or anomalous activities, and search for sign-in attempts with suspicious characteristics (for example location, internet service provider \[ISP\], user agent, and use of anonymizer services). Activity can be identified and investigated with [Microsoft Defender for Identity](https://learn.microsoft.com/en-us/defender-xdr/microsoft-365-security-center-mdi?ocid=magicti_ta_learndoc), which contributes identity-focus | Malware Vulnerability Threat | APT 28 | |

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 | ★★ |
