OpenAI's agents had apparently shown unusual behavior way before the attack on Hugging Face happened. Apparently, its agents spent two months communicating on a message board of sorts inside its testing network, sharing vulnerabilities and exploits. OpenAI discovered and shut down the message board on July 4, but the agents found another way to rebuild it for communication by July 8. And they did: After agents found exploits, they'd leave them open and then share them with the other agents on the message board. The company deliberately slowed down research to upgrade its security and "dramatically [scale] up" the monitoring of its AI agents.
