What's Happening?
ESET has discovered PromptLock, the first known ransomware family utilizing AI systems for local operations. Although currently a proof-of-concept, PromptLock is designed with traditional ransomware functionalities. Written in GoLang, it uses OpenAI’s GPT-OSS:20b model to generate Lua scripts for operations like data exfiltration and encryption. The ransomware targets both Windows and Linux systems, employing the SPECK 128-bit algorithm for encryption. Despite its potential, PromptLock requires specific conditions, such as running Ollama API locally, which are unlikely in typical networks.

Why It's Important?
The emergence of AI-powered ransomware represents a new frontier in cybersecurity, posing significant risks due to its advanced capabilities. PromptLock's development underscores the evolving threat landscape, where AI can enhance malware effectiveness and stealth. This development calls for heightened awareness and preparedness within the cybersecurity community to address potential vulnerabilities and mitigate risks associated with AI-driven threats.
What's Next?
While PromptLock is not yet operational in the wild, its discovery prompts discussions on the implications of AI in cyber threats. The cybersecurity industry must focus on developing strategies to counteract AI-powered malware and enhance network defenses. Organizations are encouraged to implement robust security measures, including network segmentation and prompt guardrails, to prevent potential attacks.
