In a recent report published by Microsoft in collaboration with OpenAI, it has been revealed that nation-state actors associated with Russia, North Korea, Iran, and China are utilizing artificial intelligence (AI) and large language models (LLMs) to enhance their cyber attack operations. Microsoft and OpenAI took action to disrupt these state-affiliated actors by terminating their assets and accounts that were utilizing AI services to carry out malicious cyber activities.

According to Microsoft, the appeal of LLMs lies in their natural language support, which enables threat actors to craft false and deceptive communications tailored to their targets' professional networks, job positions, and relationships. While no significant or novel attacks employing LLMs have been detected thus far, the exploration of AI technologies by these actors has permeated multiple phases of the cyber attack chain, including reconnaissance, coding assistance, and malware development.

The report highlights the specific uses of LLMs by each nation-state actor. Forest Blizzard (also known as APT28) from Russia conducted open-source research into satellite communication protocols and radar imaging technology, as well as used LLMs for scripting tasks. North Korean threat actor, Emerald Sleet (aka Kimusky), utilized LLMs to identify defense experts, think tanks, and organizations in the Asia-Pacific region, aid in basic scripting, and develop content for potential phishing campaigns. Iranian threat actor Crimson Sandstorm (aka Imperial Kitten) employed LLMs to create code snippets related to app and web development, generate phishing emails, and research malware evasion techniques. Additionally, Chinese threat actors Charcoal Typhoon (aka Aquatic Panda) and Salmon Typhoon (aka Maverick Panda) used LLMs for research, generating scripts, translating technical papers, retrieving publicly available intelligence information, and resolving coding errors.

In response to this growing threat, Microsoft is working on formulating a set of principles to mitigate the risks posed by the malicious use of AI tools and APIs. These principles include identifying and taking action against threat actor usage, notifying other AI service providers, collaborating with stakeholders, and ensuring transparency.

The report serves as a reminder of the evolving landscape of cyber attacks, where nation-state actors are adopting advanced technologies like AI and LLMs to enhance their capabilities. It emphasizes the importance of continued vigilance and the need for effective guardrails and safety mechanisms to counter such malicious activities.

While the implementation of these principles by Microsoft is a step toward mitigating the risks, it remains crucial for organizations and governments to remain proactive in their approach to cybersecurity and stay updated on the evolving tactics of cyber adversaries.
