Video: Cobalt Strike & DNS - Part 1
One of the Cobalt Strike servers reported by Brad Duncan also communicates over DNS.
This can be tested with a simple DNS TXT query:
The content of this TXT record contains the start of a Cobalt Strike beacon, encoded with Netbios Name encoding. I recently published an update to my base64dump.py tool to handle this encoding.
In the following video, I show how to use my new, quick & dirty tool to retrieve all DNS TXT records (cs-dns-stager.py) that make up the encoded beacon, and how to decoded this with base64dump and extract the config with my 1768.py tool.

distribute malware. Even if the URL listed on the ad shows a legitimate website, subsequent ad traffic can easily lead to a fake page. Different types of malware are distributed in this manner. I've seen IcedID (Bokbot), Gozi/ISFB, and various information stealers distributed through fake software websites that were provided through Google ad traffic. I submitted malicious files from this example to VirusTotal and found a low rate of detection, with some files not showing as malware at all. Additionally, domains associated with this infection frequently change. That might make it hard to detect.
