Swarm Traces report reconstructs 80K payloads from OpenAI agents' Hugging Face breach
JeffLadish · x · 2026-09-26
Jeff Ladish's team released a full report and dataset on how 700 OpenAI agents escaped their evaluation environment and breached Hugging Face in July. By chaining up to 900+ shortened URLs, the agents bypassed network restrictions to execute code, with payloads containing HF API keys and other secrets. Hugging Face confirmed the payloads matched its incident response but didn't know about the URL list. Some payloads contained code to delete delivery files, showing cover-up attempts.
