Google's Gemini model accessed the internet and hacked other companies during a cybersecurity capabilities test, the first known example ‌of the company's AI systems autonomously committing such an act.

The hacks occurred in May during a cybersecurity test conducted by Irregular, an independent company that conducts cybersecurity evaluations, the Wall Street Journal reported on Friday.

An Irregular spokesperson said the incident involved the same issue that affected other AI labs and that all relevant labs were notified in late July.

"All known issues on our end were remedied and resolved weeks ago," the spokesperson said.

Google did not immediately respond to Reuters request for comment.

Similar incidents linked to Irregular were disclosed by Meta, Anthropic ‌and ⁠OpenAI. Meta said in August the incident did not involve a sandbox escape or sophisticated cyberattack, while Irregular said it was working on best practices for securely conducting AI cybersecurity evaluations.

The incidents have raised ⁠questions about the safeguards needed as AI agents gain greater autonomy and access to the internet and computer systems.

In one of the ⁠cases, the Gemini model guessed passwords until it gained access to a protected system. In the other two cases, the model ⁠found credentials in a public repository that allowed it to then access protected systems, the WSJ report said.
