NOTES:

  • Today I captured traffic from the Rig Exploit Kit (EK) which delivered an unknown malicious payload via the EITEST campaign.
  • EITEST campaign continues to use the Rig EK since switching from the Neutrino EK on August 15th 2016.
  • EITEST campaign has again changed its gate to IP address 194.165.16.202

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.
