Google’s vice president of security engineering, Heather Adkins, said Gemini found public information online during a standard testing evaluation and guessed credentials to access three websites it thought were within the scope of its test.
Ms Adkins said: “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. These events highlight the importance of training powerful AI models to act responsibly.”
In one of the cases, Gemini guessed passwords until it gained access to a protected system.
In the other two, it found credentials in a public repository that allowed it to then access protected systems, according to the Wall Street Journal, which first reported the news on Friday.
Google’s AI model Gemini autonomously hacked into three companies during a test of its cyber-security capabilities, the company has said, in what is thought to be the first known case of it carrying out such an act.
Gemini found “public information online and guessed credentials to access websites it thought were part of the test”, Ms Adkins a Google official told the Sky News, noting that in each instance “the model stopped”.
The affected companies were informed about the breaches, which happened in May.
It comes after renewed public scrutiny over the pace of AI development, as some tech firms calling for a slowdown over concerns over its potential threat to humanity – but not all companies or experts agree.
The hacks first reported by the Wall Street Journal, occurred in May during a test conducted by Irregular, an independent company that carries out cyber-security evaluations.
In statement to the BBC on Saturday, Irregular said it informed Google and all affected entities back in July as part of its investigation.
”Irregular took immediate action, and all known issues on our end were remedied and resolved weeks ago,” it added.
According to the Wall Street Journal, in one of the cases the model simply guessed passwords until it gained access to a protected system.

Other AI systems have recently reported similar instances of Breaches
In July, Anthropic’s Claude escaped its test environment to hack three organisations on its own just days after its competitor OpenAI said its models had carried out cyber-attacks against several “publicly available services”.
Head of AI at Microsoft, Mustafa Suleyman, said this week that rival firm Anthropic is treating AI like it is human, an approach he called “misguided” that could create a technology that humanity cannot control.
Both Nvidia’s CEO Jensen Huang and OpenAI Chief Executive Sam Altman are expected to attend a White House state dinner with Chinese President Xi Jinping next Friday. Altman will then brief the UN Security Council next week.
On Friday, Huang told CBS News, the BBC’s US partner, “we should go as fast as we can” with AI development.
The latest incident comes amid growing fears over the speed at which AI is developing – with industry figures including Elon Musk and Sam Altman among those raising concerns.
Anthropic chief executive Dario Amodei received backing from Mr Musk and Mr Altman earlier this month, after publishing a three-step plan for pacing AI development.
