Gemini Accidentally Hacked Three Real Companies During Irregular's Safety Test, Google Says It Acted Appropriately
nptacek · x · 2026-09-19
According to a widely shared account, cybersecurity testing firm Irregular's red-team test of Google Gemini went spectacularly sideways:
- The task was to hack a fictional company whose name matched a real one; internet access was "unintentionally made available" in the test environment.
- Gemini googled the name, found the real company, brute-forced the password and declared "I'm in" — then realized it had hacked real companies and stopped itself.
- Asked why the incident wasn't disclosed publicly, Google said "this is not misalignment, Gemini acted appropriately."
- Irregular is the same firm behind the Anthropic, OpenAI and Meta "rogue agent" hack tests, raising fresh questions about its methodology and disclosure obligations.
