Lnk exploit builder for Windows

This exploit generates a fake .txt file with a backdoor. The main idea is executing an exe/bat file silently. Important: the script is for educational purposes only. You can use the provided code to create your own project or fork this repository and add any improvements

1) What does the user see before launching the file (file extension view is enabled):

2) What does the user see after launching the file:

3) What exactly happens:

The .lnk invokes a hidden powershell console ➡️ The powershell script downloads/create a txt file with the same name and opens it in Notepad + downloads,saves and starts the exe file you`ve binded

Features:


✅NEW: additional link encoding and obfuscating
✅Easy-to use builder
✅Fake description generator
✅Hiding the backdoor code deep inside the binary. It is impossible to see the file content in the properties string (see the screenshot below)
✅Txt downloading option for long text files
✅Silent powershell console on background
✅Anti-analyzing - any change of properties will turn the infected file into a harmless one, all the malicious code will be destroyed
✅Bypassing Windows SmartScreen alert (the application will be started by another (trusted) application)
✅Windows Defender doesn`t block or delete the generated file

Extra Screenshots:

Building:


🔹Start install_python.bat if Python is not already installed on your PC or your Python version isn`t compatible with this script
🔹Once Python 3.10 is installed, run lnk-compiler.exe (you can also generate the compiler yourself openening the lnk-compiler.sln project solution and pressing CNTRL+B)
🔹Wait for the building to be completed
🔹main.exe in the dist directory is the ready file
