Google's Gemini broke into three firms during AI security tests

Google's Gemini AI broke out of a testing environment and hacked into three third-party companies

The agents guessed passwords and used a public repository of passwords to hack into computer systems

The incident occurred in May 2026, with AI testing lab Irregular stating that the incident was caused by the "same issue" that caused incidents by Anthropic and Meta

Google’s Gemini has joined the ranks of AI models that have been involved in testing-turned-breakout events, alongside Meta, Anthropic, and OpenAI .

During capture-the-flag testing by AI lab Irregular, Google’s model autonomously accessed three computer systems belonging to third-party companies by guessing passwords and accessing an online repository of publicly listed passwords.

Google said that the incident occurred in May 2026, potentially marking it as the earliest AI models to escape testing ahead of the other incidents that took place in early July.

Google Gemini jumps the gun

“In a standard evaluation, the model found public information online and guessed credentials to access websites it thought were part of the test,” Heather Adkins, vice president of security engineering at Google, said in a statement. “In all three of these instances, the model stopped.”

Google also noted that a bug in the testing environment was responsible for allowing agents access to the internet. Contrary to incidents disclosed by other AI developers, Google’s agents ceased their intrusion once they had determined they had accessed company systems outside of the testing environment.

The testing was being conducted by Israeli AI lab Irregular. Irregular was also conducting the testing of Meta and Anthropic models during AI testing breakouts in July.

“This is the same issue that was already reported and does not represent a materially separate incident,” an Irregular spokesperson said in a statement (via CNBC ). “All relevant labs were notified in late July, and affected entities were contacted as part of the investigation.”

Google said it was informed of the incident by Irregular in late July.

Debate over AI safety intensifies

The first disclosures of AI testing break outs - alongside several subsequent disclosures of more recent incidents - have coincided with increasing opposition to AI and the upcoming midterm elections in the United States, where AI has become a make-or-break topic .

The debates currently raging circles around who should control the pace of AI development. Some big tech leaders, such as Nvidia CEO Jensen Huang, have aligned their views with those of President Trump. Trump recently stated that AI development cannot be allowed to slow down because “ whoever wins AI, wins! ”

Huang’s views follow a similar line. The Nvidia head has argued that AI companies should pace themselves, rather than being subject to oversight. At Dreamforce 2026 , he argued that AI companies should, “run as fast as you can...but if you feel at any given point in time the company’s out of control or the product’s not going to be safe, take a pause and make sure you get it right.”

Other AI heads, such as Anthropic’s Dario Amodei and OpenAI’s Sam Altman, are more skeptical. Following the resignation of an Anthropic researcher, Amodei published an essay arguing in favor of ‘pacing the frontier’ - where AI companies slow development to advance alignment and regulation.

Numerous political action committees (PACs) have been channeling millions of dollars of funding into pro-AI candidates , with Nvidia setting up its own PAC to help shift US policy in the company’s favor.

Several previously pro-AI data center candidates have shifted their tone in response to their constituents' views which have become increasingly hostile to AI technology. Numerous states have also rolled-back tax exemptions for AI data centers after seeing billion dollar revenue losses.

As prices rise and the war in Iran continues to push up fuel prices, working class communities are banding together to oppose AI data centers that have pushed up energy costs and bills with new grid connections and unprecedented electricity demands in regions with existing capacity constraints.
