BACKGROUND ON RIG EXPLOIT KIT:
- I'm routinely intercepting 2 versions of Rig EK as classified in an October 2016 blog post by Kafeine.
- Rig-V: a "VIP version" with new URL patterns and RC4 encryption for the payload. Used by the Afraidgate, EITest, and pseudoDarkleech campaigns.
- Rig-E: a variant with old URL patterns, but uses with RC4 encryption for the payload. Also known as Empire Pack. I often see Rig-E used by the EITest campaign.
BACKGROUND ON THE AFRAIDGATE CAMPAIGN:
- My most recent in-depth write-up on the Afraidgate campaign can be found here.

- My thanks to Justin Ragghianti who tweeted about the compromised site.
