BB17 distribution Qakbot (Qbot) activity
Introduction
Early morning Tuesday 2023-02-28, I generated an infection with a URL I found on VirusTotal after pivoting on a search for BB17-tagged distribution URLs for Qakbot (Qbot). Based on other public reports, I saw the expected Qakbot activity. Today's diary shares indicators from the infection.
Shown above: Traffic from the infection filtered in Wireshark.

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.
