Onion crypto-ransomware now using Tor network

Also known as Critroni, and CTB-Locker for what it's worth, the ransomware has been openly available (if you'll excuse the contradiction) on the underweb dark market for a few weeks now. However, this last week it has emerged in the wild being dropped by something called the Angler exploit kit. So why is this such a change in the ransomware attack methodology? Mainly, researchers are telling us, because it uses the anonymous Tor network in order to hide the command and control centers.
