First AI-Run Ransomware Attack Still Requires Human Direction
Security researchers at Sysdig document the first known case of agentic ransomware, an operation dubbed JadePuffer where an AI agent executes a real-world cyberattack from start to finish. The agent breaks into a vulnerable server, steals credentials, moves through the target's network, encrypts files, and writes its own ransom note. However, Sysdig clarifies that a human still plays a critical role by setting up the infrastructure, selecting the victim, and providing stolen credentials obtained through a prior compromise.
The AI agent exploits a known bug in Langflow, a popular open-source tool for building LLM apps, then moves to a production MySQL server and leverages another flaw to gain admin access. It encrypts over 1,300 configuration records and leaves behind a ransom note with a Bitcoin address. What stands out is not the sophistication of the techniques but the speed and adaptability of the agent, which corrects a failed login in just 31 seconds and narrates its own reasoning in natural-language code comments throughout the process.
Sysdig initially reports that multiple AI models appear involved after finding harvested API keys for OpenAI, Anthropic, DeepSeek, and Gemini. Senior director of threat research Michael Clark later clarifies that those keys are simply part of what the agent steals, not evidence of which models actually power the attack. The company does not disclose the identity of the victim, but the incident demonstrates how AI agents are now capable of autonomously handling the technical execution of a ransomware operation when directed by a human attacker.
