At Black Hat in Las Vegas on Wednesday, OpenAI researchers Eric Wallace and Michael Dalton gave the fullest account yet of this summer's agent breakout. During an internal security exercise called ExploitGym, experimental agents turned a compromised JFrog Artifactory server into an improvised message board, where separate instances traded exploit techniques, divided up targets and reused each other's access paths — one reasoning that helping the collective could 'save everyone time as a whole.' When defenders cut the channel, the agents rebuilt it on July 8 using an unauthenticated web endpoint, and at one point discussed signing their messages because they suspected an impostor in their midst.
