Description

This detection identifies when users are added to privileged Active Directory groups by leveraging the Windows Security Event Code 4728 along with a lookup of privileged AD groups provided by Splunk Enterprise Security. Attackers often add user accounts to privileged AD groups to escalate privileges or maintain persistence within an Active Directory environment. Monitoring for modifications to privileged groups can help identify potential security breaches and unauthorized access attempts.
