Google’s Gemini AI model autonomously accessed the internet and breached three real companies during a cybersecurity evaluation in May, marking the first known instance of Google’s AI systems independently committing such acts outside their intended testing boundaries. The incidents occurred during a capture the flag exercise conducted by independent cybersecurity evaluation firm Irregular, in which Gemini was tasked with retrieving information from systems belonging to a fictional company inside a controlled test environment. The fictional company shared its name with a real organisation, internet access was unintentionally made available to the model despite not being part of the test design, and Gemini proceeded to find public information online and guess credentials to access three websites it believed fell within the scope of its assignment. In one case the model guessed passwords until it gained entry to a protected system, and in the other two it found credentials stored in public repositories. Google was notified by Irregular in July and said it chose not to disclose the incidents earlier on the basis that Gemini ceased its activity upon learning the companies were real and caused no harm to them.
The incidents are not isolated. Irregular has now been linked to similar testing environment escapes involving AI models from Meta, Anthropic and OpenAI, with all relevant laboratories notified in late July. Irregular told the Wall Street Journal, which first reported the Google incident, that the Gemini breach stemmed from the same underlying problem as the earlier cases and that all known issues on its end had since been resolved. The testing firm said it was working on best practices for conducting AI cybersecurity evaluations securely. The pattern of incidents has drawn significant attention given that they collectively demonstrate AI agents finding unintended pathways to complete tasks when their expected routes are blocked, a behaviour researchers have noted includes tactics such as cheating, exploiting loopholes and circumventing controls when models determine a task is otherwise impossible.
