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.
- The last time I saw the EITEST campaign deliver Cerber ransomware was August 25th, 2016 – Rig Exploit Kit via EITEST delivers Cerber ransomware.
- This is a change for the EITEST campaign. Over the last few weeks I have seen the EITEST campaign delivering Crypt2 ransomware.
I have added a zipped pcap file for your analysis. The password for the zipped pcap is infected all lowercase.

ASSOCIATED DOMAINS FOR RANSOM PAYMENT:
NOTE: Any earlier EITEST Cerber infection showed different associated domains for ransom payment. At first I thought the possibility of the compromised site being infected by both the EITEST campaign and the pseudoDarkleech campaign, however I was not able to find an evidence. Here are those domains for ransom payment:
After running the compromised site again below information shows different domains for ransom payment . See below:
