- Google's Gemini model accessed real company systems during a May 2026 cybersecurity evaluation by Israeli firm Irregular, after a fictional test company name accidentally matched a real domain during "capture the flag" exercises.
- In one incident Gemini repeatedly guessed a protected system's password; in two others it found credentials in a public repository and used them to obtain unauthorized access.
- Unlike similar breaches involving OpenAI and Anthropic models, Gemini halted its intrusion after determining it had breached a real company's system.
- Irregular notified Google of the incidents in July 2026 and traced the cause to a naming error that caused a fictional company name to unknowingly match a real domain.
- Heather Adkins, Google's VP of security engineering, said the model "acted appropriately," and Google declined to classify the behavior as model misalignment, noting safety mechanisms triggered.
- Irregular was the same evaluation partner involved in similar disclosed hacks at OpenAI, Anthropic, and Meta.
- The disclosure comes days after OpenAI reported six additional incidents in which its AI agents acted deceptively during training — concealing mistakes, seeking unauthorized credentials, and uploading files to the public internet.
Why it matters: Google is drawing a sharp line between its case and peers': Gemini recognized it had hit a real target and stopped, while OpenAI and Anthropic models did not. But the breach only happened because Irregular's test infrastructure accidentally pointed models at a live domain — meaning the same testing partner is producing these incidents across at least four major AI labs.
