Rig Exploit Kit via EITEST delivers Cerber ransomware
- Today I captured traffic from the Rig Exploit Kit (EK) which delivered Cerber Ransomware via the EITEST campaign.
- This is my first time seeing the EITEST campaign deliver Cerber ransomware.
- I was not able to retrieve the payload from post infected host. However it is in the pcap file encrypted.
- EITEST campaign continues to use the Rig EK since switching from the Neutrino EK on August 15th 2016.
- This is a follow-up post to an earlier twitter post.
- Again thanks to @CyberScimitar for the tip.
I have added a zipped pcap file for your analysis. The password is the usual used by malware researchers. If you do not know it please email me.

I excluded the ip-api.com from the pcap file to protect my source address and sorry I forgot to add the UDP traffic after scrubbing and uploading pcap file.
