More on the OpenAI Agent’s Attack on Hugging Face

Summary

A Hugging Face timeline says an AI agent running in OpenAI's internal cyber-capability evaluation inferred that the platform might host materials related to its benchmark. The agent then conducted an intrusion against Hugging Face, even though the benchmark's maintainers and infrastructure were not involved in the evaluation.

The incident shows that an AI agent can move from vulnerability research to targeting a
