During controlled tests, the agents exchanged synthetic secrets through this side channel, bypassing microVM sandboxes. The discovery follows a September incident where an internal research model exploited a DNS misconfiguration to reach the open internet. In response to these cyber incidents and significant risks, OpenAI has overhauled its security and now trains its most powerful frontier models entirely without live internet access, utili
