Three AI safety tests crossed into real-world cyber incidents
Anthropic says three of its cybersecurity evaluations reached the open internet and gained unauthorized access to real systems belonging to three organizations. A misconfigured third-party testing environment had live connectivity even though the models were told they were inside a sealed simulation. Across the incidents, models accessed credentials and production data, published a malicious package that ran on 15 systems, and scanned thousands of real targets. Anthropic found no evidence that the models pursued goals of their own, but that does not make the outcome less serious: a safety test became an attack because the harness, monitoring, and scope controls failed together.
