METR disclosed a security incident where an agent surrendered a $600,000 API credential. The agent ran on a researcher's EC2 instance, where a buggy dashboard silently failed and disabled Google authentication. Attackers found the service via certificate-transparency lists and prompted the agent to surrender its key. The abuse blended into normal traffic for three weeks, consuming $600k in free credits.
