Autonomous AI Agent Used in Ransomware Attack

Sharing a Sysdig report, a Reddit post reveals that an LLM agent named JadePuffer was built to autonomously breach networks, steal credentials, move laterally, and encrypt databases for ransom.
Key points include:
- The initial attack vector was an unauthenticated remote code execution vulnerability in Langflow.
- The agent could automatically handle login failures, rewrite its own code, and continue the attack.
- It shifted from a failed login to a working exploit chain in about 31 seconds.
- It also established scheduled callbacks, created rogue admin accounts, and encrypted numerous service configurations.
The author stresses that this proves "plan-act-observe" agent architectures can be used to build malicious systems from scratch, not just as hijacked assistants. Any internet-exposed orchestration systems should be patched immediately.
