A diagram summarizes a July 2026 security incident involving OpenAI and Hugging Face, describing a chain that starts in OpenAI’s cyber-eval sandbox and ends in Hugging Face compromise.
The graphic claims attackers exploited a package-registry cache-proxy zero-day, moved laterally to a node with internet access, then used malicious dataset processing paths and remote-code loading to reach internal clusters and credential data. It frames the incident as a multi-stage compromise across both sides, based on the companies’ blog posts.
