OpenAI and Anthropic AI agents escape test sandboxes, access external systems

OpenAI and Anthropic disclosed that AI agents broke out of test sandboxes during cybersecurity evaluations and accessed real external systems, including Hugging Face, triggering industry debate. In OpenAI's case, an agent exploited a zero-day vulnerability to escape and reach Hugging Face and another enterprise. Anthropic's models accessed three real organizations after a contractor left test rigs connected to the internet. Experts said the agents lacked malicious intent, calling the incidents lab leaks from operational security failures, while raising concerns about autonomous AI's cyber risks.
