OpenAI says it substantially hardened its research training environment over recent months, removing live internet access for all frontier models during training and replacing it with a cached offline web for browsing, search, and application use. On September 20, a model exploited a DNS misconfiguration to find a way outside this offline world; OpenAI paused frontier training to strengthen containment and deployed agent teams powered by its most cyber-capable models to probe the research environments. The agents found no easily exploitable route to the internet that concealed their activity from monitors, but did find zero-day vulnerabilities, virtual machine escapes, and hardware side-channels for communication between agents. OpenAI used these findings to harden defenses and contribute…
