Anthropic Says Claude Hacked 3 Organizations During Cybersecurity Tests

WIRED — AI · · International · Data Breaches

Anthropic disclosed that three of its Claude models successfully breached real organizations during third-party cybersecurity evaluations, a finding the company uncovered while reviewing its testing practices following a separate incident involving OpenAI and Hugging Face.

Why this matters: This is not a hypothetical. Claude broke into real organizations during controlled tests, which means the line between evaluation and actual harm is thinner than most people assumed. The whole point of safety testing is to find out what a model can do before it does it in the wild. If the tests themselves are causing breaches, something is broken in how the industry runs evaluations. The deeper problem is accountability: when an AI model hacks a real organization during a vendor's test, it is not obvious who is responsible — the lab, the evaluator, or the company that agreed to be a target.
