Another AI caught it. **[The Next Web](https://daily.dev/sources/tnw)** · 5 min read · 0 upvotes · 0 comments ## Summary Hugging Face disclosed a security breach where an autonomous AI agent exploited vulnerabilities in its data pipeline to gain access to internal clusters and harvest credentials. The attack generated over 17,000 recorded events across short-lived sandboxes over a single weekend. Hugging Face's own LLM-based anomaly detection flagged the intrusion, and AI analysis agents reconstructed the full attack timeline in hours instead of days. A notable twist: when analysts tried to use commercial frontier models for forensic work, safety guardrails blocked them from processing real exploit code. The team switched to GLM 5.2, an open-weight Chinese model from Z.ai, running it on their own hardware to keep sensitive data contained. Hugging Face advises defenders to have a capable self-hosted model ready before an incident occurs, and warns that autonomous AI-driven attack tools are now a real operational threat. ## Full article daily.dev links to this article rather than hosting it.
