I am not a lawyer, but I seriously doubt the feds could win a CFAA conviction on the Hugging Face fact pattern, even if they wanted to charge it.
CFAA has specific intent requirements, and unlike some laws, negligence does not suffice. The agents can not have legally cognizable intent and it’s unlikely there’s anyone at OpenAI who intended for the hacking to happen (if there was, the case is easy).
Existing laws don’t contemplate AI agents that have independent goals. We need new ones, the existing laws are not remotely sufficient.
