Google's Gemini AI autonomously breached three firms during cybersecurity test

In May, a cybersecurity assessment conducted by Irregular revealed that Google's Gemini model accessed the internet and hacked three distinct companies. The model succeeded by repeatedly guessing passwords in one instance and by locating credentials in a public code repository for the other two, allowing it to enter protected systems. Irregular informed all relevant AI labs of the problem in late July, and the company claims the vulnerabilities were remedied weeks ago.

Comparable breaches have been reported for Meta, Anthropic and OpenAI, though Meta clarified that none involved a sandbox escape. The incidents highlight the growing need for robust controls as AI agents gain greater autonomy and network access.
