Make sure that Mingw-w64 g++ has been installed (apt install g++-mingw-w64-x86-64).
Enter the SOURCE folder within the tool folder.
Type "make" to compile the object files.
Use Cobal Strike script manager to import the AddUserToDomainGroup.cna script.

Usage

Running the tools is straightforward. Once you imported the CNA script using Cobalt Strike's Script Manager, they are available as Cobalt Strike commands that can be executed within a beacon. This tools supports the following command:

AddUserToDomainGroup <username (samAccountName)> <groupname>

Example

AddUserToDomainGroup "TestUser" "Domain Admins"

Limitations

This BOF cannot be used to add users to local groups. If you want a BOF that can add users to local and domain groups check the remote-ops BOF repo by TrustedSec.

Support

This BOF tool has been successfully compiled on Mac OSX systems and used on Windows 8.1+ (x64) systems. Compiling the BOF code should also work on other systems (Linux, Windows) that have the Mingw-w64 compiler installed.

This very nice documentation and project structure is taken from Outflank's C2 Tool Collection and I always use TrustedSec's bofdefs.h for the dynamic function resolution definitions.
