BACKGROUND ON RIG EXPLOIT KIT:
- I usually run across 2 versions of Rig EK: Rig-V (Rig 4.0) and Rig-E (Empire Pack).
- Rig-V is what security researchers called Rig EK version 4 when it was only accessible by "VIP" customers, while the old version (Rig 3) was still in use.
- I currently call it "Rig-V" out of habit.
- The proper name for Rig-E is "Empire Pack". Empire Pack a variant of Rig EK as described by Kafeine here.
- I haven't seen Empire Pack traffic in 2017 yet, but I often see it from the EITest campaign (when EITest is distributing something other than CryptoMix/CryptFile2 or Cerber).
BACKGROUND ON THE PSEUDO-DARKLEECH CAMPAIGN:
- My most recent in-depth write-up on the pseudoDarkleech campaign can be found here.
