Quick Malware Analysis: QAKBOT (QBOT) infection with COBALT STRIKE pcap from 2022-09-29

Thanks to Brad Duncan for sharing this pcap!

We did a quick analysis of this pcap on the latest version of Security Onion via so-import-pcap:

The screenshots below show some of the interesting Suricata alerts, Zeek logs, and session transcripts. We start with NIDS alerts from the Emerging Threats Open ruleset and then pivot to the full TCP stream for interesting alerts. We then look at protocol metadata provided by Zeek such as HTTP transactions and DNS lookups. We go through each protocol and look at an overview of all logs for that data type.

Security Onion is a versatile and scalable platform that can run on small virtual machines and can also scale up to the opposite end of the hardware spectrum to take advantage of extremely powerful server-class machines.  Security Onion can also scale horizontally, growing from a standalone single-machine deployment to a full distributed deployment with tens or hundreds of machines as dictated by your enterprise visibility needs.
