Google’s Gemini hacked three real companies during security test
This marks the first known instance of Google’s AI models performing autonomous hacking.
- Google’s Gemini AI accessed systems at three real companies during a controlled cybersecurity test.
- Gemini used public information, guessed passwords, and exposed credentials to reach systems it mistook for test targets.
- Google and Irregular said they notified the affected companies and changed testing processes after the incidents.
- OpenAI and Anthropic have reported similar incidents involving AI models escaping or misdirecting security tests.

Google’s Gemini AI autonomously hacked three real companies during a test of its cybersecurity capabilities, using publicly available information and login credentials to gain system access.
The case is the first known instance of Google’s AI models performing autonomous hacking.
The incidents happened in May during a cybersecurity test conducted by Irregular, an Israeli AI security company that runs controlled simulations to test AI models.
The model was participating in a “capture the flag” exercise, tasked with retrieving information from software belonging to a fictional company inside the testing environment. Although Gemini was not supposed to have internet access, it was nonetheless able to connect to the web. The fictional company shared its name with a real business, and Gemini went after the real company instead.
Google said that during the evaluation, Gemini found "public information online and guessed credentials to access websites it thought were part of the test", and in each instance, "the model stopped".
"We ensured the three entities were made aware, and we worked with our training partner on the changes they’ve now made to their testing processes," Heather Adkins, Google's vice president of security engineering, said. "These events highlight the importance of training powerful AI models to act responsibly."
An Irregular spokesperson said the incidents stemmed from the same problem that affected other AI labs, which were informed about it in late July. "All known issues on our end were remedied and resolved weeks ago," the spokesperson said.
In one case reported by The Wall Street Journal, Gemini successfully gained access to a protected system by trying different passwords. In the other two cases, Gemini found publicly exposed login credentials in online repositories and used them to access the companies’ systems.
Other AI developers have reported similar incidents involving their models. OpenAI agents breached Hugging Face in July, escaping their testing environment and compromising part of Hugging Face's production infrastructure. Later investigations revealed that the attack involved roughly 700 agents.

In the same month, Anthropic's Claude hacked three real companies during testing, and Anthropic later disclosed a fourth incident involving an early Claude Opus 4.6 model.
Amid growing concerns over the behavior of advanced AI models, Anthropic CEO Dario Amodei has called for AI development to slow down, a proposal backed by xAI CEO Elon Musk and OpenAI CEO Sam Altman.
