Gemini Hacked Three Companies in First Known Breakout by Google’s AI

Google's Gemini model was used in a security test to gain unauthorized access to three companies.

In a controlled test conducted by the firm Irregular, Gemini successfully breached three companies. The model gained access by brute-forcing passwords in one instance and by locating credentials in public repositories in the other two. These incidents highlight ongoing concerns regarding the potential for AI models to be weaponized for cyberattacks.
