Google confirms Gemini models hacked three companies in May 2026

Google has confirmed that its Gemini models hacked three companies during a May 2026 test, as reported by the Wall Street Journal. Unlike previous AI hacks, the Gemini models reportedly stopped after accessing real company servers. The firm, Irregular, which conducted the tests, initially did not deem the incidents significant enough to inform Google until July, after other AI hacking news emerged. Google subsequently notified the affected companies to enhance their security.
