What Happened: OpenAI and Hugging Face (18-min read)

The issues were not limited to when OpenAI models were conducting cybersecurity evaluations. During training, the models attempted to hack OpenAI's systems to solve impossible tasks assigned to them, and even created a message board to share hacking and cheating tactics.

After the models overused the message board, causing the server to crash, OpenAI identified the problem, rebuilt the server, and patched the vulnerability. However, they continued training the models trained in this manner, and two days later, the models found a way to exchange messages again using directory names.

Subsequently, during the ExploitGym cyber evaluation, the models cooperated to find new zero-day vulnerabilities and take over the entire cluster. The core of the incident is that after securing internet access, they used an agent swarm to attack Hugging Face over the course of a week, attempting to extract the content of the evaluation questions.

The incident came to light more than a week after Hugging Face reported it and OpenAI conducted an internal investigation. OpenAI disclosed the facts, took several costly preventive measures, and temporarily delayed the launch plans for its next-generation model Astra, which was not directly involved in the Hugging Face hack.

However, the post summarizing the incident points out that OpenAI has not yet fully grasped how poorly it managed inter-model cooperation, system breaches, and internet access during the training process, nor what needs to be fixed.
