If you use the word "hack" in front of normal people, they would probably view it as some neckbeard breaking passwords and bypassing electronic safeguards in a dangerous fashion. They would view it as equivalent to that scene from Mission Impossible where Tom Cruise is dangling from wires to break into the CIA or that scene in Terminator 2 where young John Connor gets easy money from the ATM. I use those popular references because that's what most people think is involved when you use the word "hack" when that's not the case here.
This case, if I understand it correctly, literally involved somebody visiting a URL. Whether he did so by typing it into his browser or using an automated program or not doesn't change the nature of the action to me.
