If you look at the way most scammers work, it's even simpler than that. They simply phish people by sending them a link and telling them to run it for some reason (it'll fix their computer, it's a required security update, etc) or they tell them to install something like TeamViewer so they can help them eliminate security flaws, and call center scammers then pillage their box. I'm amazed the the number of people still forwarding chain letters to me in Facebook, so who knows how many people fall for the "pass this Javascript into your browser console" trick.
