Rig Exploit Kit via EITEST delivers GootKit Banking Malware
NOTES:
- Today I captured traffic from the Rig Exploit Kit (EK) which delivered GootKit banking malware via the EITEST campaign.
- It appears the EITEST campaign has switched from the Neutrino EK to the Rig EK.
- I last saw GootKit on July 5th, 2016 when it was delivered via the Neutrino Exploit Kit and the Rig Exploit Kit [HERE].
- Thanks to Brad at Malware-Traffic-Analysis.net for helping me identify the exploit kit.
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.
