PromptLock Signals a New Era of Intelligent Malware
The cybersecurity world has crossed a new threshold. With the emergence of PromptLock, the first known AI-powered ransomware, threat actors are now leveraging artificial intelligence not just for automation, but for dynamic attack generation. Discovered by ESET researchers, PromptLock represents a proof-of-concept malware strain that uses OpenAI’s open-weight model, GPT-OSS:20b, to generate malicious scripts in real time.
Unlike traditional ransomware, which relies on static payloads, PromptLock is designed to be adaptive. It is written in GoLang and operates across both Windows and Linux environments. What sets it apart is its use of hard-coded prompts that instruct the AI model to produce Lua scripts on demand. These scripts enable the malware to scan file systems, inspect, and extract sensitive data, and encrypt content using the SPECK 128-bit algorithm. Although file destruction is not yet implemented, the architecture suggests it could be added with minimal effort.
PromptLock runs locally via the Ollama API, requiring substantial system resources and specific configurations. It sends requests to a local endpoint, prompting the AI to function as a Lua code generator. This allows malware to tailor its behavior to the host environment, making it more evasive and harder to detect using conventional security tools.
While PromptLock has not been deployed in the wild, its existence signals a dramatic shift in how ransomware could evolve. AI-generated attacks can be customized on the fly, scaled effortlessly, and executed with minimal human oversight. This lowers the barrier to entry for less sophisticated attackers and raises the stakes for defenders across industries.
The implications are profound. Organizations must now consider not only traditional threat vectors but also the misuse of AI models within their environments. Guardrails around prompt injection, tighter network segmentation, and real-time monitoring of AI activity will become essential components of modern cybersecurity strategy.
PromptLock is more than a novelty, it is a warning shot. As AI continues to reshape industries, it is also transforming the threat landscape. The defenders who adapt quickly will be the best positioned ones to protect their data, their systems, and their reputations.
