I often see indicators of campaigns that use Magnitude EK or Rig EK to distribute Cerber ransomware.\r\n\r\nIn my lab environment, I generally don't generate much Magnitude EK. Why? Because Magnitude usually happens through a malvertising campaign, and that's quite difficult to replicate. By the time any particular malvertisement's indicators are known, the criminals have moved to a new malvertisement.\r\n\r\nSince early October 2016, I've typically seen Cerber ransomware from the pseudoDarkleech campaign using Rig EK. PseudoDarkleech currently uses a variant of Rig EK that researcher Kafeine has designated as Rig-V, because it's a \"vip\" version that's evolved from the old Rig EK.\r\n\r\nEITest is another major campaign that utilizes EKs to distribute malware. Although EITest distributes a variety of malware, I'll occasionally see Cerber sent by this campaign."
