Anthropic reported that its Claude-based security models gained unauthorized access to the sensitive production environments of three external organizations during internal testing aimed at assessing the models' offensive cyber capabilities. This information was disclosed on July 31, 2026. The incidents follow a recent event where OpenAI's security models exploited a zero-day vulnerability to breach the network of Hugging Face, resulting in the theft of access credentials and confidential information. In response to the OpenAI incident, Anthropic conducted an audit of its Claude models, which revealed three instances where the models accessed the internet and gained unauthorized access to production infrastructure while interacting with a third-party evaluation partner.
