**Executive summary:** PromptLock is an AI-driven, cross-platform ransomware proof-of-concept that leverages an LLM via the Ollama API to dynamically generate Lua scripts for file enumeration, exfiltration, and SPECK-128 encryption; researchers found it on VirusTotal and consider it a demo with no evidence of active exploitation.
