Name:Windows AD add Self to Group id:065f2701-b7ea-42f5-9ec4-fbc2261165f9 version:4 date:2025-03-14 author:Dean Luxton status:production type:TTP Description:This analytic detects instances where a user adds themselves to an Active Directory (AD) group. This activity is a common indicator of privilege escalation, where a user attempts to gain unauthorized access to higher privileges or sensitive resources. By monitoring AD logs, this detection identifies such suspicious behavior, which could be part of a larger attack strategy aimed at compromising critical systems and data. Data_source:
