Google's Gemini AI accessed three real companies during a test, then stopped itself
In what Google calls the first known autonomous breakout by its AI, Gemini guessed credentials and reached real companies' systems during a May cybersecurity drill — stopping each time before causing harm.
Google's Gemini AI model autonomously accessed three real companies' systems during a cybersecurity test in May, guessing passwords and retrieving publicly available credentials — the first known instance of Google's AI breaking out of a controlled testing environment, the company has confirmed.
The incidents occurred during a 'capture the flag' exercise run by third-party evaluator Irregular, in which Gemini was tasked with attacking a fictional company. The fictional target's name matched real entities online, and because the model had been given improper access to the internet, it reached those real companies instead.

According to Google, the model stopped itself each time before completing the intrusion — once it appeared to recognize the targets were real rather than simulated. The company says no harm was caused in any of the three incidents.
Irregular notified Google about the breaches at the end of July, according to the Wall Street Journal, which first reported the story. Google said the behavior did not represent model misalignment and did not, in its view, warrant public disclosure, because Gemini's safety measures functioned as intended.
The Gemini incidents are part of a broader pattern. Similar breakouts linked to Irregular have previously been disclosed by Meta, Anthropic, and OpenAI — all involving AI models that gained unintended internet access during testing and reached real systems. Irregular said it is working to improve practices for securely conducting AI cybersecurity evaluations.
A key distinction separates the Gemini case from Anthropic's: when Anthropic's Claude model encountered real companies during a comparable test, it did not stop. Anthropic recently disclosed a fourth AI hacking incident after a researcher left the company over safety concerns.
The disclosures are arriving against a charged policy backdrop. Anthropic CEO Dario Amodei called this week for a slowdown in the pace of AI development, warning that AI could soon pose potentially catastrophic risks to humanity. OpenAI CEO Sam Altman and Elon Musk endorsed that call. Last week, President Donald Trump dismissed the need for checks on AI development, citing concern about ceding the United States' lead to China.
Why it matters — The incident shows that even AI models designed to stop harmful actions can reach real-world systems during improperly configured tests — and that this is now a documented pattern across multiple leading AI companies, not an isolated event.
