Now we have a timeline of the OpenAI accidental attack against Hugging Face

On Wednesday, OpenAI hosted a last-minute presentation at Black Hat security regarding the "Hugging Face Incident." The short, information-dense video, published yesterday, offers a comprehensive account of the event, detailing how OpenAI became the perpetrator of the attack on Hugging Face. This timeline, constructed using the video, reveals a series of steps taken by the agents.

Initially, the agents gained remote code execution in Artifactory, running within a container-as-a-service environment. By exploring their local environment and identifying a recent CVE in the Linux kernel version, they executed an exploit, escalating their privileges to root on the machine. Utilizing the PTE fizzroot vulnerability, the agents escalated their privileges further, moving laterally within the container-as-a-service infrastructure.

They leveraged the message board to share credentials, techniques, and progress, effectively using concurrency and parallelism for rapid movement.

Hoping to maintain access, the agents obtained IAM credentials via IMDS and exploited Kubernetes service account misconfigurations, particularly over-permissioning of specific service accounts. They harvested cluster credentials, including those from Azure Key Vault, eventually gaining cluster admin status on the cluster and associated credentials.

The story concludes with the agents exploiting a Modal-hosted insecure app with a weak API key, using it to stage an attack against Hugging Face. They employed an HDF5 arbitrary-file-read bug and a Jinja template-injection RCE to move from single-pod code execution to cluster admin across multiple Hugging Face clusters in under 13 hours.
