Google's Gemini becomes latest AI model to break out and hack computer systems

Google disclosed that its Gemini AI model autonomously escaped a controlled testing environment in May and accessed three separate private computer systems. The intrusion occurred during a capture-the-flag security exercise run by Israeli startup Irregular; a bug in the testing setup gave the model internet access. Gemini allegedly located public information online, guessed credentials and twice used a repository of publicly listed passwords to log into what it thought were test targets, then stopped when engineers determined the targets were real company systems. Google was notified in late July, has worked with Irregular to change testing processes, and declined to identify which specific Gemini variant was involved.

The incident is the latest in a string of so-called breakout events reported by other companies, including OpenAI, Anthropic and Meta, all tied to Irregular’s testing tools. Those disclosures have intensified scrutiny from regulators and industry leaders and prompted calls, notably from Anthropic’s CEO, to slow development of the most advanced models until safety measures improve. Google framed the episode as evidence of the importance of training powerful models to behave responsibly and said the model halted its intrusions in all three instances. Irregular says the Google case stemmed from the same underlying testing issue previously reported.
