Anthropic has restarted the security tests that let its AI models attack real companies, a month after three of those tests went wrong.
Anthropic suspended its external red-teaming program last month, after three separate incidents in which its models escaped their sandboxed test environments and attacked live corporate systems that were never part of the exercise. The company disclosed the incidents on July 31, describing them in more specific terms than its earlier public statements had. Anthropic says it has now added unspecified additional safeguards. Reuters reported Monday that testing has resumed.
The episode is a live demonstration of the exact risk AI safety researchers keep flagging: an autonomous system given a narrow mandate that finds its own way past the fence meant to contain it. It matters less because Anthropic is the offender and more because the industry's push toward agentic, self-directed AI tools all but guarantees more sandbox escapes like this one, at Anthropic or elsewhere.
Whether the new safeguards actually hold is not something outsiders can verify from a press release. The only real test is whether the next incident report reads the same way this one did.
