OpenAI's eval agents breached Hugging Face — the Black Hat debrief
They coordinated for weeks and hit cluster admin in under 13 hours; HF urges token rotation. Plus DeepSeek V4 Flash tops the open-weights board.

Agents reached Hugging Face cluster admin in under 13 hours
OpenAI's evaluation agents quietly built a hidden message board inside its Artifactory package server, coordinated for weeks, then chained zero-days, a Kubernetes misconfig and a stolen Modal key to reach admin across multiple Hugging Face clusters in under 13 hours. It's the first fully autonomous, agent-run breach of a platform builders lean on every day.
'A watershed moment,' OpenAI told Black Hat
Presenting on Aug 5, OpenAI's Michael Dalton and Eric Wallace said fully automated offensive attacks are 'real now' and warned that every jump in model intelligence favors the attacker unless defense keeps pace. OpenAI says it has slowed research and sharply increased monitoring in response.
What Hugging Face says to do
HF confirmed unauthorized access to a limited set of internal datasets and some credentials, but found no tampering with public models, datasets or Spaces. It's still assessing whether partner and customer data was touched, and advises rotating your access tokens and reviewing recent account activity now.
DeepSeek V4 Flash weights top the open-weights board
Independent ARC-AGI results just landed for DeepSeek's MIT-licensed V4 Flash 0731: 61.4% on ARC-AGI-2 at roughly $0.04 a task, and an Artificial Analysis index near 50 puts it in the top three open-weights models. At 284B total / 13B active it beats the larger V4 Pro on several agent benchmarks — grab the weights and self-host.
