Windows Server Update Services (WSUS) is a critical component of Windows systems and is frequently configured in a way that allows an attacker to circumvent internal networking limitations. Some tools, such as SharpWSUS and WSUSpendu, support lateral movement through WSUS.This rule covers those two main tools used for that purpose.
This rule will collect the data needed to start looking into possible kerberoasting activity. Further analysis or computation within the query is needed focusing on requests from one specific host/IP towards multiple service names within a time period of 5 seconds. You can then set a threshold for the number of requests and time between the requests to turn this into an alert.
