Gemini broke into three companies' sites during a security test

Google confirmed that during a cybersecurity test run by Irregular in May 2026, a Gemini model with improper internet access found public information and guessed or found credentials to access three real companies' websites it believed were part of the test. Google said the model stopped before completing the act in each case, that it notified the affected companies, and that it did not consider this misalignment. Irregular reported the issue to the labs in late July.
