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.

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.
Read why I've reconsidered my stance in my fresh new post: "The Hunter's Paradox: Is it time to embrace automated threat hunting?"

If you think you have a "supply chain", you're wrong. What you actually have is a "supply web".
Changing your mental model can help you gauge supply web risks more accurately.

If AI driven attacks become more prevalent, it'll only be a matter of time before attackers push the token burden on to their victims, using the AI that's already (probably) there.
I'm calling it "living off the lAInd".*
*Jokey name. Probably will happen, though.
