Rig Exploit Kit via EITEST delivers Cerber ransomware from 109.234.34.247

NOTES:

  • Today I captured traffic from the Rig Exploit Kit (EK) which delivered Cerber  ransomware via the EITEST campaign.
  • The EITEST campaign has changed it’s injected script on compromised sites from an obfuscated hex script to a javascript redirect.
  • Thanks to Baber for sharing information on compromised site.

I have added a zipped pcap file for your analysis. The password for the zipped pcap is infected all lowercase.
