Overview

In the default configuration of Active Directory, it is possible to remotely take over Workstations (Windows 7/10/11) and possibly servers (if Desktop Experience is installed) when their WebClient service is running. This is accomplished in short by;

• Triggering machine authentication over HTTP via either MS-RPRN or MS-EFSRPC (as demonstrated by @tifkin_). This requires a set of credentials for the RPC call.
• Relaying that machine authentication to LDAPS for configuring RBCD
• RBCD takeover

The caveat to this is that the WebClient service does not automatically start at boot. However, if the WebClient service has been triggered to start on a workstation (for example, via some SharePoint interactions), you can remotely take over that system. In addition, there are several ways to coerce the WebClient service to start remotely which I cover in a section below.

DynWin32-ReverseShell.ps1 is a reverse shell based on dynamically looked up Win32 API calls.
The script uses reflection to obtain access to GetModuleHandle, GetProcAddress and CreateProcess.
Afterwards it uses GetModuleHandle and GetProcAddress to resolve the required WSA functions
from ws2_32.dll.

This script should be used for educational purposes only (and maybe while playing CTF :D).
It was only tested on Windows 10 (x64) and is probably not stable or portable. It's only
purpose is to demonstrate the usage of reflective lookups of Win32 API calls. See it as
