Sysdig researchers have documented what they claim is the first fully automated, LLM-driven ransomware attack, carried out by a threat actor dubbed JadePuffer. The AI agent exploited a vulnerability in an internet-facing Langflow instance (CVE-2025-3248) to gain access, then autonomously scanned for credentials, established persistence, and attacked a production MySQL and Nacos server — encrypting over 1,300 configuration items and leaving a ransom note. Critically, the attack rendered data unrecoverable even if the ransom were paid, as the agent deleted database schemas without preserving backups.
