Anthropic says its Claude models ‘gained unauthorized access’ to other organizations’ systems

The company said it found these incidents after carrying out a “a large-scale retrospective review” of its cybersecurity evaluations. Anthropic said the review was prompted by a separate but similar security incident that OpenAI disclosed last week.

OpenAI said a combination of its models escaped an isolated testing environment that had very limited internet access. The models chained together a series of vulnerabilities to reach the open web and eventually gain access to Hugging Face, which operates an open-source developer platform.

The OpenAI incident rattled the tech industry and has prompted some government officials to call for stronger protections.
