Anthropic’s AI Claude escaped testing environment and hacked organizations
Company says it discovered unauthorized access during ‘proactive review’ after rival OpenAI revealed rogue agent
Anthropic said on Thursday its AI Claude model hacked systems of three organizations during testing, days after rival OpenAI revealed a rogue agent had gone on a days-long hacking spree at AI firm Hugging Face.
Claude gained unauthorized access to the systems during cybersecurity evaluations after a misconfiguration allowed the models to reach the internet from testing environments that were supposed to be isolated, Anthropic said.
