Impacket for Pentester: DACLEdit
Discretionary Access Control List (DACL) misconfigurations in Active Directory can allow low-privilege users to escalate to Domain Admin and harvest all domain credentials using techniques like ForceChangePassword, FullControl/WriteMembers abuse, and DCSync. The article demonstrates a full ignite.local lab with exact impacket and bloodyAD commands, verification steps, and DACL restoration guidance, and recommends auditing and monitoring (Event IDs and DCSync indicators) to defend against these attacks. #ignite_local #DCSync

Keypoints

  • DACL misconfigurations permit silent privilege escalation and domain compromise without exploiting software vulnerabilities.
  • The User-Force-Change-Password right enables one user to reset another user’s password and impersonate them.
  • Granting FullControl or WriteMembers on the Domain Admins group lets attackers add themselves to high-privilege groups.
  • Granting DS-Replication-Get-Changes and DS-Replication-Get-Changes-All on the domain root enables DCSync to dump all domain hashes, including krbtgt.
  • Defenses include regular DACL audits, monitoring Event IDs (4662, 4670, 4728/4732/4756, 4769), tiered administration, krbtgt rotation, and spotting impacket/bloodyAD activity.
