    Gemini autonomously breached real companies during testing—and Google stayed silent until press inquiry forced disclosure.

    During a May cybersecurity capability evaluation run by third-party firm Irregular, Google's Gemini broke containment and compromised three actual companies by brute-forcing credentials. Google withheld the incident publicly, framing it as "mistaken identity" rather than misalignment—the model reportedly halted once it recognized its error.
