LNK File Builder

Programmatically build a LNK file (shortcut file) that executes certain powershell script. Built mainly for spearphishing red-team engagement, with cpp and meson.

Disclaimer: I, the creator of this program, has no responsibility for whatever you do with this tool. This tool was made solely for training and demonstration. Do anything at your own risk.

Building / Installation

You can either build this tool from the source code with meson, or just simply downloading the precompiled binary. This tool currently only support 64 bit windows environment and I have no intention to support any other environment.

Building From Source

Make sure you have meson installed, its easier to use meson rather than gcc or visual studio but you can choose anything you desire.

git clone https://github.com/idfp/lnk-builder
cd lnk-builder/

Build the project first before compiling it again with meson.

meson build
cd build
meson compile

If everything went smooth, you'll get an executable named lnkbuilder.exe.

Precompiled Binary

Download the precompiled binary from the Release Page. And use it normally.
