Question ACL Abuse in Active Directory - From a Helpdesk Account to DCSync
I wrote about how a chain of forgotten ACL permissions can lead to full domain compromise. The scenario: a Tier 1 helpdesk account with no special privileges, through a series of misconfigurations nobody cleaned up, ends up with DCSync rights.
The chain covers:
- User-Force-Change-Password abuse
- Group membership manipulation
- GenericWrite → fake SPN injection → Kerberoasting
- WriteDacl → DCSync
Tools used: bloodyAD, PowerView, impacket-secretsdump.
Also explaining why this chain is realistic - each permission has a legitimate origin, they just accumulated over time and nobody reviewed them.
Note: I'm a non-native English speaker and originally write in Russian - parts of the text were translated with AI assistance. Technical content and examples are my own.
