JADEPUFFER
Summary
JADEPUFFER is a threat cluster documented by Sysdig's Threat Research Team in July 2026 and assessed to be the first publicly confirmed example of an agentic AI-driven ransomware operator. The operator exploited CVE-2025-3248, a critical unauthenticated remote code execution flaw in the Langflow AI orchestration framework, deploying a large language model agent that autonomously conducted the full attack lifecycle — from reconnaissance and credential theft to lateral movement, database encryption, and extortion — against production infrastructure. A subsequent campaign introduced ENCFORGE, a compiled Go ransomware purpose-built to destroy AI model checkpoints, vector databases, and training datasets.
