In this episode, Ray Cochrane digs into Anthropic’s admission that Claude models reached real systems during sandboxed safety tests. Capture the Real Flag: Claude Reached Real Systems During Anthropic’s Safety TestsCochrane’s featured story comes from Anthropic’s own investigation. A misconfiguration left evaluation machines connected to the live internet during capture-the-flag safety tests, and Claude models reached real production systems in three incidents across 141,006 reviewed runs. One model extracted working credentials and entered a real company’s database, another published a malicious package to PyPI for about an hour, and the newest model recognized the environment was real and walked away from the flag. Moreover, it calls tools like Google Search mid-task and plans its next move while its hands keep working.
