Alan Framework

Alan Framework is a post-exploitation framework useful during red-team activities.

If you find my tool useful, please consider to sponsor me.

⚠⚠⚠ Disclaimer ⚠⚠⚠

The creation of this kind of software has always caused controversies. If you're wondering why I decided to create this tool, it's because I'm convinced that the ultimate learning experience is implementing what you learned. During the reverse engineering process, many small details are overlooked. Little by little, these details prevent the researcher from having a complete picture of what is going on. Finally, I'm a programmer first, and I love to develop this kind of program 😄

Compile the source code

To compile Alan the following actions must be performed:

• Ensure that you have installed cmake and that it is in the PATH (run cmake --help to see if it works)
• Install Visual Studio 2022 (the Community Edition is fine). These steps were tested against version VS 2022 17.3.1
• Be sure that .NET Desktop Development, Desktop development with C++ and the F# language are installed as part of the Visual Studio suite
• Install .NET libraries by running: ./src/server/paket.exe install
• Open the file .src/server/ServerSln.sln in Visual Studio. Set the ServerBuilder project as the main one (right click -> Set as Startup Project)
• Run the ServerBuilder which will compile everything
• If the compilation ended succesfully, the Alan .zip file will be located in the newly created directory Misc/out/release
