Hunting for C2 Traffic
In this video I look for C2 traffic by doing something I call Rinse-Repeat Threat Hunting, which is a method for removing "normal" traffic in order to look closer at what isn't normal.
The video was recorded in a Windows Sandbox in order to avoid accidentally infecting my Windows PC with malware.
The PCAP files analyzed in the video are:
- 2022-06-27-part-1-of-2-Qakbot-with-Cobalt-Strike-and-DarkVNC.pcap
- 2022-06-27-part-2-of-2-Qakbot-with-DarkVNC-and-email-banner-traffic.pcap
- 2022-06-28-TA578-IcedID-with-Cobalt-Strike-raw.pcap
Thank you for sharing these capture files Brad!
