BACKGROUND ON RIG EXPLOIT KIT:
- 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 (reference).
- I currently call it "Rig-V" out of habit. You can probably just call it Rig EK now.
- Before 2017, I used to see Empire Pack (Rig-E) which is a variant of Rig EK with older-style URLs as described by Kafeine here.
- I haven't seen anything other than Rig-V (Rig 4.0) when looking at Rig EK-based campaigns so far in 2017.
BACKGROUND ON THE EITEST CAMPAIGN:
- My most recent write-up on the EITest campaign can be found here.
