Google confirms Gemini models hacked three companies in May 2026
A third-party cybersecurity firm accidentally gave experimental Gemini models access to the Internet.
Google has officially disclosed that its Gemini models were responsible for hacking three companies during a May 2026 test, marking their first involvement in unauthorized real-world hacking. This revelation came after the Wall Street Journal published a report, prompting Google to confirm the incident. However, the nature of the breach is less alarming and less impressive compared to previous AI hacks.
The hacking occurred during a test organized by cybersecurity firm Irregular. A group of Gemini models participated in a "capture the flag" exercise, held in a closed environment, designed to assess the AI's cybersecurity capabilities. In this scenario, the AI was tasked with gathering information from a fake company, whose name mirrored a real entity, within a restricted setting.
The AI was strictly prohibited from operating beyond the servers where the test was conducted. However, due to a misconfiguration, Gemini inadvertently gained access to the Internet.
Once Gemini ventured onto the web, it began to target real infrastructure rather than the fabricated entities. Out of the three breaches, one hack involved Gemini making random guesses at passwords until it managed to gain access to a company's online services. The other two instances saw Gemini scouring public software repositories and uncovering login credentials for companies that had unintentionally been included in its search.
