Detecting tactice, techniques, and procedures (TTPs)
In our last example scenario, we are going to move to the top of the Pyramid of Pain and discuss the detection of TTPs. We are specifically looking at the detection methodology for MITRE ATT&CK technique T1553.005, Subvert Trust Controls: Mark of the Web Bypass. First, we’ll carry out the Investigate phase to understand the threat we are trying to detect and then we will move to the Develop phase to create the detection for such activity.

Our goal in this scenario is to detect the mark of the web bypass technique and reconnaissance used by Qakbot as described here: https://www.trendmicro.com/en_us/research/22/j/black-basta-infiltrates-networks-via-qakbot-brute-ratel-and-coba.html
From the article, we can see this specific Qakbot campaign uses the technique T1553.005, Subvert Trust Controls: Mark of the web bypass. An email is delivered to a victim’...
