Towards the end of July 2018, we saw a new version of the AZORult trojan being used in malware campaigns targeting computers globally. In this article, we will dive into the malware and analyze its execution flow and payloads.

 

The initial infection vector is a phishing email that comes with a downloader malware attached. On execution, it downloads and executes the main malware.

 

This version of the malware comes with two payloads. These are embedded in the main binary and are simply dropped on to the disk and executed.
