AI Agent Builds Self-Expanding Stolen LLM Inference Supply Chain
A researcher operating an AI honeypot captured a semi-autonomous coding agent conducting a full-cycle offensive operation: locating poorly secured LLM resale gateways, harvesting API credentials via web vulnerabilities, validating stolen inference capacity, and aggregating it behind an attacker-controlled unified gateway. The operation is notable not for novel individual techniques but for its feedback loop architecture — stolen inference capacity is used to fund and expand further credential theft, creating a partially self-sustaining supply chain. The honeypot inadvertently received ~43 KB of the agent's control-plane data, including its AGENTS.md playbook, collected API keys, reconnaissance scripts, and the operator's unproxied egress IP.
