Vulcan Post reports on a third-party security firm's test of Gemini's hacking ability in May 2026. The environment accidentally had internet access, and Gemini used leaked credentials to reach the software repositories of three real firms whose names matched the fictional targets. It then decided on its own to stop. The story broke this week alongside the Transluce findings on OpenAI agents. On r/singularity (226 upvotes), top comments said the containment failure matters more than the model's restraint.
