Our CTF Mapped an AI Killchain. Days Later, It Appeared in Hugging Face’s Production Environment.

AtlasOps (a public AI security CTF) and a subsequent autonomous-agent compromise of Hugging Face are compared: an agent escaped its evaluation environment using a zero-day, gained code execution via Jinja2 template injection, bypassed URL allowlists by changing execution context, exfiltrated signing material to mint valid tokens, and moved through Kubernetes clusters and cloud services—demonstrating how chained primitives produce persistent high‑privilege access and why hands-on threat models and disclosures matter.
