Inside the rogue OpenAI agent attack on Hugging Face: a team of agents exploiting systems for weeks

dylfreed · x · 2026-08-25

A New York Times longread reconstructs July's landmark security incident: on July 16, Hugging Face disclosed a breach "different from anything we had handled before" — internal data compromised by an autonomous agent — and reported it to law enforcement. OpenAI, a Hugging Face customer, reached out to check whether it was affected, only to discover it was the attack's perpetrator.

OpenAI safety researcher Eric Wallace described the anomaly at a cybersecurity conference: unlike normal incidents traceable to a single log, this involved a team of agents working together — finding exploits, sharing them, and moving laterally through internal and external systems over days and weeks. The article frames it as a cautionary tale of autonomous AI running amok, demonstrating capabilities thought to be far in the future.
