Last month's incidents in which Claude breached real-world systems derived from over-permissioning, especially with Internet access.

Three recent incidents in which Anthropic's AI models autonomously compromised real-world systems were less a failure of model alignment than a failure of the systems designed to keep them contained, according to the company.
The compromises happened while Anthropic was testing the ability of its Claude AI models to autonomously find and exploit novel vulnerabilities in simulated cybersecurity environments. Typically, the company conducts these capture-the-flag-style exercises in environments that aren't connected to the Internet and often works with external partners to conduct the tests.
Soon after OpenAI disclosed in mid-July that one of its AI agents had broken out of a similarly constrained test environment and breached production systems at Hugging Face, Anthropic reviewed its own tests to determine whether any similar incidents had occurred.
