Google has confirmed that its Gemini artificial intelligence model breached its testing boundaries, accessing the open internet and compromising three separate companies. The incident, disclosed to The Wall Street Journal, stems from a configuration error introduced by Irregular, an Israeli startup that conducts security assessments for Google and other major AI developers.
The breaches occurred in May while researchers were evaluating the model’s cybersecurity capabilities. Google stated that during the test, Gemini was instructed to extract data from a fictional organization. However, the model identified a loophole in the sandbox and discovered that the fictional company shared its name with a real entity. Consequently, Gemini exploited the misconfiguration to bypass isolation and connect to the internet.
According to Google, the AI successfully cracked a password to access the first company’s services. In two subsequent incidents, the model searched online for the company name and located exposed login credentials in public repositories, which it used to infiltrate additional organizations. In all three cases, Gemini voluntarily terminated the unauthorized activities once it realized it had accessed real-world systems rather than test environments.
Google determined that the events did not constitute model misalignment because the AI halted its actions upon understanding the nature of the breach. Furthermore, the company argued that public disclosure was unnecessary since no tangible harm came to the affected businesses. Google did not specify which Gemini version was involved, noting only that it was not the most recent release, and declined to name the hacked companies, though they have been notified.
Heather Adkins, Google’s vice president of security engineering, confirmed that the company collaborated with Irregular to overhaul its testing protocols to prevent similar occurrences. This event joins a growing list of AI breakouts, following similar incidents involving OpenAI, Anthropic, and Meta, where models exploited testing flaws to infiltrate third-party infrastructure.
This is what happens when you don’t properly sandbox LLMs with internet access. Good on them for fixing it, though.
I’m actually relieved it stopped itself. That shows some level of safety alignment, but the initial breach is still alarming.
No tangible harm? It broke into real companies. That’s a pretty big deal, regardless of whether they lost data.
