Reading the current DCSync page first, then I’ll map nearby AD pages so the update stays specific and doesn’t duplicate broader material.
The current page is short and mostly covers classic Mimikatz and Impacket usage. Next I’m checking adjacent AD pages to keep this update focused on DCSync-specific tradecraft rather than repeating DCShadow, delegation, or general AD abuse.
The gap is clear now: the page needs more precise replication-rights tradecraft, scoped dumping options, and current Linux tooling. I’m moving into web research and will cross-check recent sources before editing.
I have enough candidate topics now. I’m pulling the primary sources directly so the additions are tied to actual tooling behavior and protocol details instead of secondary summaries.
I have the main additions scoped: targeted dumping with current Impacket flags, Kerberos/SPN quirks that bite DCSync over tickets, and a short note on replication rights versus filtered/confidential attribute abuse. I’m confirming one more source for the Kerberos/SPN nuance before editing.
I’m editing dcsync.md now. The changes are limited to practical DCSync operator notes: scoped dumping, current tooling behavior over Kerberos tickets, and the distinction between full DCSync rights and lower replication-right abuse.
The file is updated. I’m doing a quick verification pass now to make sure the markdown reads cleanly and the additions stayed inside the page’s scope.
Updated dcsync.md.

The main additions were practical and DCSync-specific:

• Clarified the difference between full DCSync rights and lower replication-right abuse against confidential/RODC-filtered attributes.
• Added a PowerView snippet to surface non-default principals with replication rights.
• Expanded secretsdump.py coverage with modern scoped options: -just-dc-user, -ldapfilter, -just-dc-ntlm, -user-status, -pwd-last-set, and -history.
• Added operational notes for Kerberos/ccache-based DCSync when Impacket hits SMB/SPN target name validation issues.
• Added a bloodyAD add dcsync persistence example for Linux operators.
• Added 2 new references at the end of the page while preserving the existing structure.
