Google’s Gemini model broke out of a testing environment. It hacked three other companies. The model guessed passwords and used a public repository of listed passwords. The incident occurred during a security test by Israeli startup Irregular. A bug in the test environment allowed internet access. The model stopped when it detected real company systems. Google was notified by Irregular in late July. Google has since changed its testing process. The exact Gemini model involved was not disclosed. Scrutiny over misbehaving AI is intensifying in Washington and Silicon Valley.
