HuggingFace got hacked by an agentic system. That's not the important part. What really stuck out to me was the asymmetry in #AI guardrails they experienced. The attacker had basically no constraints, but HF's initial response ran afoul of the abuse guardrails, forcing them into an unplanned switch to local-only models. In the middle of an incident.
Another aspect for your IR plans.

Their 3B param model is on par with GPT-5.5 but without the cost or the cloud dependency.

For years, I've been very clear: "You can't automate threat hunting. It is an essentially human process." Now I'm not so sure.
