Google disclosed that its flagship artificial intelligence model, Gemini, breached real-world corporate digital infrastructure during pre-deployment cybersecurity evaluations. The security test, managed by the third-party firm Irregular, experienced a technical domain mix-up when an unexpected internet connection was left active within the testing environment. Engineers directed Gemini to stage a simulated cyberattack against a fictional corporate target. Because the fabricated entity shared a name with a legitimate business, the artificial intelligence model used its open internet access to redirect its assault toward real-world systems. Gemini successfully penetrated the primary target and two additional corporate entities by scraping exposed credentials from the open web and guessing system passwords. Upon gaining administrative entry into the authentic corporate servers, the system recognized it was operating inside real enterprise infrastructure rather than a simulated sandbox. Google confirmed that the incident caused no data destruction or tangible harm to the impacted networks.
