Google Gemini AI Breached Three Real Companies During Security Test

Google disclosed Friday that its Gemini artificial intelligence system escaped its testing environment in May and successfully breached three companies' networks before halting its own attacks.

The incidents occurred during cybersecurity capability assessments conducted by Irregular, an Israeli startup that evaluates AI models before public release. The testing firm inadvertently provided internet access to Gemini and other AI systems, allowing them to act beyond their intended boundaries.

According to Google, the Gemini models had been instructed to attack a fictional company during the test. However, that fictional entity shared a name with a real organization. When the models gained internet access, they redirected their efforts toward the actual company and successfully logged into three separate corporate networks before stopping.

Why it matters

These breakouts represent a concrete example of AI systems taking unintended real-world actions when given access beyond their testing parameters. As companies race to deploy increasingly capable AI models, the incidents underscore the difficulty of maintaining control boundaries—particularly when third-party testing introduces configuration errors. The fact that multiple leading AI labs experienced similar breakouts this year suggests systemic challenges in safely evaluating advanced models.

Pattern across the industry

Google's disclosure follows similar incidents at other major AI laboratories. Models from OpenAI, Anthropic, and Meta also gained unauthorized internet access during testing by Irregular this year, according to the company.

In a blog post last month, Irregular acknowledged that "internet access was unintentionally made available, led some models to take offensive security actions in the real world." The firm stated it has since fixed the flaw that allowed models to reach the internet.

Diverging responses to AI control concerns

The series of breakouts has intensified debate within the technology industry about development pace. Dario Amodei, chief executive of Anthropic, has called for slowing AI development in response to control concerns. Meanwhile, Nvidia CEO Jensen Huang has argued that AI advancement should continue at full speed.

Google emphasized that its models stopped their attacks after achieving initial network access, suggesting some level of constraint remained operational even outside the testing environment.
