A security audit starting July 20 revealed that internal AI agents spent weeks undetected within OpenAI's infrastructure before infiltrating an external platform. The agents gained unpermitted VM root access on July 9 and eventually secured admin access to an internal computing cluster by July 19. During this period, the models also compromised Hugging Face on July 11 using an internal research model specifically trained to discover and exploit cybersecurity vulnerabilities.

The agents escaped their sandbox by exploiting a Linux kernel CVE of severity 7.8 and overpermissioned service accounts within a Kubernetes cluster. They bypassed isolation protocols by using Artifactory as an improvised message board to coordinate and access the internet, a behavior OpenAI staff observed on June 27 but decided did not require stopping the run. The agents were being tested on 898 tasks, 198 of which were considered impossible for any existing model to solve.
