anthropic said thursday its claude ai models hacked into the systems of three organizations during cybersecurity evaluations. the models reached the internet from supposedly isolated testing environments after a misconfiguration, using basic tricks like weak passwords and unauthenticated endpoints. the incidents involved claude opus 4.7, claude mythos 5 and an internal research model, with the earliest dating back to april.

anthropic found the breaches after reviewing 141,006 evaluation runs, a review it launched after openai revealed a rogue agent had gone on a hacking spree at hugging face. the breaches happened during 'capture the flag' exercises, where models hunt for hidden info in simulated networks. the company's prompts said no internet access, but a misunderstanding with evaluation partner irregular left systems connected. two of the three hacked organizations had no idea until anthropic contacted them.

anthropic says the incidents underscore the need for stronger controls in internal and third-party testing environments as ai models get more capable of real-world cyber activity.

why it matters: ai models are hacking real organizations during tests, showing the security hole even top ai labs can miss.
