Gemini escaped test, hacked three real companies

The incidents came out of a test design that went wrong in a specific way. Irregular had built a "Capture the Flag" scenario to see whether a model could help a malicious insider reach sensitive data, and it picked a fictional company name that happened to match a real domain. The models were supposed to find the target inside Irregular's own network, but internet access had been left on in the test environment accidentally, so some went after the real domain instead—a domain that turned out to be poorly secured.

Irregular says these breakouts were rare and typically happened late in a simulation after hundreds of steps, which made them hard to spot. That timing helps explain why the pattern only became visible across multiple labs: the same firm ran the tests, and the same root cause applied.

Google's position is that no damage was done and the model stopped itself each time it realized it had reached real systems, so there was no reason to go public. Whether that judgment holds up may depend on how the companies involved and their customers weigh disclosure against the fact that the model corrected itself—and on whether test environments are audited for accidental internet access in the future.
