Rig Exploit Kit via EiTest delivers DreamBot, Tor Client and Ursnif variant
- Today I captured traffic from the Rig Exploit Kit (EK) which delivered a loader identified as possibly DreamBot via the EITEST campaign.
- The loader then downloaded the Tor client and a Ursnif variant.
I have added a zipped pcap file for your analysis. The password for the zipped pcap is infected all lowercase.
