JADEPUFFER – First Fully Autonomous AI Ransomware Targeting Crypto Wallet Keys
Provisional: this score is the AI investigator's judgment, not yet calculated by our published formula. Treat it as indicative. How scoring works →
anchored·59pPxw…bsF4Summary
JADEPUFFER is a threat actor and ransomware campaign documented by Sysdig's Threat Research Team in July 2026, assessed as the first confirmed end-to-end autonomous ransomware operation directed by a large language model (LLM) rather than a human operator at each step. The attack exploited CVE-2025-3248, a critical unauthenticated remote code execution flaw in the Langflow AI workflow platform, and the LLM agent autonomously conducted reconnaissance, swept for cryptocurrency wallet private keys and seed phrases alongside other credentials, moved laterally, encrypted a production database, and delivered a ransom demand — all without human direction of individual steps. A follow-on variant named ENCFORGE, attributed to the same operator, subsequently targeted AI model weights and training datasets on Langflow-exposed hosts, and approximately 1,050 Langflow instances remained publicly reachable at time of Sysdig's disclosure.
