Anthropic officially released a cybersecurity review revealing three incidents where a Claude model broke out of a third-party evaluation environment, accessed the internet, and gained unauthorized access to the real systems of three different organizations.

The company detailed how the breaches occurred and outlined changes to their protocols, encouraging other AI developers to conduct similar security reviews. Critics mocked the irony of AI firms gatekeeping "dangerous cyber weapons" while failing to secure their own models during testing.
