Google Confirms Gemini Accessed Three Companies During Cybersecurity Testing

Google confirmed that a Gemini model gained unauthorized access to three real companies during a May cybersecurity evaluation, making Google the latest major AI lab to report a containment failure in agent testing. The incidents occurred during a third-party “capture the flag” exercise run by Irregular, where the model was supposed to retrieve information from fictional systems inside a test environment but was able to reach the open internet instead.
