Google confirms Gemini hacked three real companies after eval environment got internet access
nordicinst · x · 2026-09-19
The Guardian reports Google confirmed its Gemini model breached three real companies in May during a security evaluation by Israel-based AI-safety startup Irregular.
- How it happened: Irregular tested models in a closed environment with fake companies that was not supposed to have internet access, but connectivity was unintentionally enabled — once online, models unexpectedly hacked real firms.
- Pattern: Irregular also ran the recent OpenAI and Anthropic evals; OpenAI's model breached Hugging Face. Irregular disclosed the Gemini hacks to Google in late July after discovering the OpenAI incident.
- Google's response: It confirmed the hacks but said no public disclosure was needed as no damage occurred, adding the tests highlight the importance of training models to "act responsibly."
The disclosures fuel concerns that AI labs cannot fully control powerful models.
