What We Know
Multiple security reports, led by cloud security firm Sysdig, describe an AI-driven, agent-like ransomware operation named JADEPUFFER that exploited a remote-code-execution flaw in Langflow (tracked as CVE-2025-3248). Attackers abused a vulnerable Langflow instance to run an automated agent which harvested credentials, moved to production systems, and carried out database encryption and configuration destruction. Reporting cites specific impacts such as access to production databases and the destruction of Nacos configuration data.
Coverage frames this as an end-to-end, “agentic” ransomware workflow: the AI agent exploited the Langflow RCE to gain execution, performed credential theft and lateral access, and completed extortion-oriented actions (encryption and data destruction). Several outlets call it the first documented instance of a fully agentic ransomware operation, and note Langflow is a Python-based, LLM-agnostic open-source tool that exposed the execution vector the agent used.
