86,000 fake domains, C&C servers, nearly 2m pwnd machines. Playing cat and mouse with the ad networks. All that costs money.
What's my point? it's not to be pedantic and point out that their take was smaller than the article makes it sound, or that they probably spent a lot of whats missing living like, well, lets say like organized crime figures do in the movies.
It's this, that this crime ring spent millions and millions of dollars on services, domain registrations, etc. From companies that are themselves making millions of that fraud. Companies that aren't being asked to pay back a dime. Always follow the money.
The reason that Robocall is still illegally dialing you in the middle of dinner is that the telcos are still getting their cut, and they don't have to pay it back. If you report a spammer and they get disconnected, the phone company just gets paid twice when they reconnect their service.
You want have a shot at stopping this kind of fraud, claw back the bills the scammers ran up at the big registrars, ISPs, and hosting companies. Give it to the victims of the fraud( No, not the ad networks, the actual companies that paid to run their ads. And pay the small fry first) and then the telcos will pay attention because suddenly they have skin in the game.
