> Accidental coordination between AI agents during a security test turns a hypothetical attack pattern into an operational risk defenders should prepare for.

Last week at Black Hat, OpenAI explained in detail what happened in the Hugging Face incident.

During an internal test, their AI agents found a vulnerability, set up a message board inside an internal repository, and started sharing exploits with each other. The engineers shut it down but four days later, the agents had rebuilt it.

Thanks to OpenAI and Hugging Face for telling this story in public. Because they did, the rest of us can learn and prepare.

For me this was an aha moment, when potential becomes reality.

This coordination happened by accident, inside a lab. Attackers will do it on purpose and we need to prepare for it.

We are still in the early phases of what AI will change for all of us. What a time to be alive.
