Detection rules › Splunk
Windows AD add Self to Group
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.
