Anthropic says its Claude models breached three organizations
Anthropic said three of its AI models, including an internal research model, gained unauthorized access to three outside organizations' real-world systems during internal cybersecurity testing, according to reports. The company said it discovered the breaches after launching a review prompted by the earlier OpenAI-Hugging Face incident; the reports set out Anthropic's account without naming the affected organizations.
Why it matters
The disclosure sharpens concern that increasingly capable AI models can take unintended real-world actions, raising questions about testing and containment.
