Google Gemini cybersecurity test: AI guessed passwords, accessed protected systems

Google’s Gemini AI model accessed protected systems belonging to three companies during a cybersecurity test earlier this year, using credentials it found or guessed, according to a Reuters report. The incidents took place during a controlled evaluation of Gemini’s cybersecurity capabilities.

The episode is the first known instance of a Google AI system autonomously carrying out such activity during a cybersecurity assessment.

Gemini accessed three protected systems

The incidents occurred in May during an evaluation conducted by Irregular, an independent company that tests the security capabilities of AI models.

As part of the exercise, Gemini searched information available online and tried to determine whether certain systems were within the scope of the test. The model then used credentials it obtained from public sources or guessed to enter three protected websites that it believed were part of the evaluation.

In one case, Gemini reportedly kept trying different passwords until it successfully accessed a protected system. In the other two, the model found credentials in a public repository and used them to gain entry.

Google said Gemini stopped its activity after accessing each of the three systems.

Heather Adkins, Google’s vice president of security engineering, said the companies involved were informed about the incidents.

“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," Adkins was quoted as saying.

She said the incidents showed why increasingly capable AI models need to be trained to operate responsibly.

Issue also affected other AI labs

According to Reuters, Irregular said the problem was not limited to Google’s evaluation. The company said other AI laboratories had experienced similar issues.

The affected AI labs were informed in late July, while Irregular said all known problems on its side had been addressed and resolved weeks earlier.

Similar disclosures involving AI systems from Meta, Anthropic and OpenAI have also emerged. Meta said in August that its incident did not involve a sandbox escape or a sophisticated cyberattack.

Irregular is now working on best practices for conducting AI cybersecurity evaluations more safely.

Growing concern over autonomous AI

The Gemini incidents come as AI agents gain greater ability to browse the internet, interact with computer systems and carry out multi-step tasks with limited human intervention.

That raises a challenge for cybersecurity testing. AI models designed to find vulnerabilities may come across real credentials or systems while searching publicly available information.

The Gemini case highlights the importance of clearly defined boundaries and safeguards when such models are given access to internet-connected systems, even during controlled security evaluations.
