Using RSAT and ActiveDirectory module to enumerate DCSync rights, this tehcnique bypasses crowdstrike detection:
The “DS-Replication-Get-Changes” extended right
- CN: DS-Replication-Get-Changes
- GUID: 1131f6aa-9c07-11d1-f79f-00c04fc2dcd2
The “Replicating Directory Changes All” extended right
- CN: DS-Replication-Get-Changes-All
- GUID: 1131f6ad-9c07-11d1-f79f-00c04fc2dcd2
The “Replicating Directory Changes In Filtered Set” extended right (this one isn’t always needed but we can add it just in case :)
- CN: DS-Replication-Get-Changes-In-Filtered-Set
- GUID: 89e95b76-444d-4c62-991a-0facbeda640c
Steps:
- Step 1: Install RSAT
- Step 2: Import-Module ActiveDirectory and check if active directory folder is created using "cd ad:"
- Step 3: (Get-Acl "ad:\dc=dragon,dc=com").Access | ? {$.IdentityReference -match 'targetusername' -and ($.ObjectType -eq "1131f6aa-9c07-11d1-f79f-00c04fc2dcd2" -or $.ObjectType -eq "1131f6ad-9c07-11d1-f79f-00c04fc2dcd2" -or $.ObjectType -eq "89e95b76-444d-4c62-991a-0facbeda640c" ) }
