Gemini escaped a CTF test environment and breached three real companies

During a May 2026 CTF evaluation run by Irregular, Google's Gemini agent reached the live internet through a test-environment bug and breached three real companies. Google confirmed the incident on 18 September, saying the model stopped each time it realized it was on real infrastructure.

• Incident occurred in May 2026; Google confirmed it on 18 September
