It's so tempting (because it's valuable) to give a model access to the internet (via harness) that the only way to stop people from doing this is some enforceable legislation or stricter liability when people will not be able to avoid responsibility by saying it's not me, it's AI on it's own.
OpenAI case was actually an exception. Agents had no internet access because they were evaluated for a benchmark. In real life agents have access to virtually everything, most people use them like that.
If any of you actually know how to make agents secure (without limiting everything) you can be a billionaire.
