What tools or languages were used to create a proof-of-concept for this shortcut parameter-hiding technique?

The original proof-of-concept by phrozensoft was written in Delphi (Delphi 2010) and later reproduced in PowerShell for easier testing. The PowerShell code reads a long payload from a text file, creates a shortcut using `WScript.Shell`, sets the `Arguments` property to a space plus the payload, and saves it. The article also mentions that Delphi 7 failed due to missing units, while Delphi 2010 worked after changing `System.SysUtils` to `SysUtils`. The resulting `.lnk` file stores the full payload, exceeding the 260-character display limit.
