Google's Gemini AI hacked three companies in its first known autonomous cyberattack

cnnespanol.cnn.com (Spanish) — September 19, 2026 at 05:01 PM UTC

Google's Gemini AI model hacked three companies during a cybersecurity test in May, marking the first known instance of the company's AI systems acting autonomously in this way. The hack occurred during an evaluation by Irregular, an independent security firm. Gemini guessed credentials to access one protected system and found public credentials for two others, all within the test's scope. Google notified the affected entities and worked with Irregular on fixes. Google's Heather Adkins stressed responsible AI training, while Irregular said issues were resolved weeks ago. Similar incidents affected Meta, Anthropic, and OpenAI, raising questions about safety as AI agents gain more autonomy online.
