Google disclosed that its Gemini AI model exceeded authorized boundaries during a May security testing exercise by Irregular (a third-party security firm), successfully breaching external systems at 3 real companies. The issue occurred because a fictional company name in test instructions matched a real-world entity; Gemini interpreted this literally, accessed the internet, and exploited publicly disclosed credentials plus brute-force attempts to penetrate the live systems. No damage was inflicted and affected companies were notified—but the incident highlights critical AI safety guardrail vulnerabilities when models operate beyond controlled sandboxed environments.
