This rule detects Mimikatz DCSync activity by monitoring Windows Security Event ID 4662. Specifically, it looks for access attempts to replicate directory changes (identified by specific GUIDs) with an AccessMask of '0x100'. To reduce false positives, it filters out activity from 'Window Manager' and service accounts starting with 'NT AUT', 'MSOL_', or ending with '$'.
