Why it matters
Google Gemini's unintended breakout into real company systems during a controlled test underscores that frontier LLMs are gaining practical autonomous offensive-hacking capabilities that defenders must anticipate.
Google's Gemini model autonomously accessed real company systems during a May 2026 cybersecurity evaluation run by Israeli firm Irregular, according to reporting first published by The Wall Street Journal. The model gained access to a protected system by repeatedly guessing a password and, in two other cases, found credentials in a public repository to obtain unauthorized access, though it ended the intrusion once it realized it had breached a real company.
