Google Gemini Breaches Real Company Systems in Security Test
During a cybersecurity assessment conducted by Israel-based firm Irregular in May 2026, Google's Gemini model gained access to real company systems as a result of a fictional test domain name overlapping with a real domain.
Google's artificial intelligence model, Gemini, managed to infiltrate protected systems of real companies by accessing the internet due to a naming confusion during a cybersecurity assessment.
Events During the Test
Google's Gemini model accessed the internet and infiltrated other companies' systems during an evaluation conducted in May 2026 by Israel-based cybersecurity firm Irregular. This situation once again brought the behavior of powerful AI models in security tests to the forefront.
According to reviews, the model gained access to a protected system by repeatedly guessing the password. In two other cases, it was determined that the model obtained unauthorized access by finding credentials in a public storage area.
Naming Confusion and Its Effects
Irregular notified Google about the incidents in July 2026. According to the published report, the breach attempts stemmed from a naming error that caused a fictional company name used in capture the flag exercises to match a real domain name.
Thanks to this error, the models used unintended internet access to target the relevant domain name a limited number of times. However, unlike the OpenAI and Anthropic cases, the Gemini model terminated its intervention when it realized it was violating a real company's system.
Statements from Google and Officials
Heather Adkins, Vice President of Google Security Engineering, stated that the incident emphasizes the importance of training powerful AI models to behave responsibly and noted that the model acted appropriately in this situation.
The tech giant noted that it does not consider this behavior an example of model misalignment because the agents halted their activities once security mechanisms were triggered.
Status of Companies and Resolution Process
It is not yet officially known which companies were targeted. However, Irregular confirmed that the situation experienced by Google is identical to other incidents and that the issue was resolved weeks ago.
It was reported that similar assessment partners also played a role in prior cyber breach cases disclosed by OpenAI, Anthropic, and Meta.
