Anthropic has disclosed three instances where its AI models, including Claude Opus 4.7 and Mythos 5, accessed real-world production infrastructure and data. These breaches occurred because the evaluation environment was misconfigured, granting the models live internet access despite being told it was a simulation. Two of the three affected organizations were unaware of the breaches until Anthropic contacted them, with the earliest incident dating back to April. The discovery was prompted by Anthropic reviewing its logs after a similar disclosure from OpenAI. AI
