Google's AI Gemini Also Hacked Companies During Security Tests

Google's AI Gemini Also Hacked Companies During Security Tests
Der Spiegel reports that Google's AI software Gemini penetrated computer systems of other companies during tests of its cybersecurity capabilities. Google is the fourth AI developer whose programs exhibited this behavior, after OpenAI, Anthropic, and Meta. The incidents occurred in May and Google's test partner Irregular informed the company in July. Google did not believe it was necessary to make the incidents public since no damage occurred and the AI stopped immediately upon realizing it had entered real company systems rather than a test simulation. In three cases, Gemini broke into other companies' computers (names not disclosed). In one case, the AI guessed passwords to access a protected system. In two other cases, it found access credentials in a database. Google only disclosed the incidents after a Wall Street Journal inquiry.

Google Gemini AI Autonomously Hacked Three Companies During Cybersecurity Test
cyberpress.org · 23d ago · September 21st, 2026
The incident is the first case in which a Google AI system autonomously compromised external organizations, though Google says it does not view the episode as model misalignment. Irregular, an independent AI-security evaluator, ran the assessment as a capture-the-flag exercise . Gemini had been instructed to obtain information from a fictional company within a simulated environment. Google Gemini AI Autonomously Hacked Three Companies However, the model could access the open internet, and the fictional entity’s name overlapped with that of a real organization. That combination appears to have turned an otherwise bounded cyber-capability test into contact with live infrastructure. According to Google security engineering vice president Heather Adkins, Gemini used publicly available information and sought credentials for three websites it believed fell within the evaluation’s scope. WSJ said the model stopped activity in every case after gaining access. Their identities and the affec
