Hello everyone,
does someone know how to create a extension spoofer / have a source code?

Add the extension you want to spoof to to the end of the file name in reverse e.g. if you want to spoof test.exe to a .jpg add gpj to the file name (testgpj.exe) and then insert U+202E (Right-to-left override) character before the spoofed extension (test[U+202E]gpj.exe). You probably could have just googled this.

PHP Code
<?php
private static void HideExtension(string fileName, string extension)
{
char[] array = Path.GetExtension("." + extension).ToCharArray();
Array.Reverse(array);
string fileNameWithoutExtension = Path.GetFileNameWithoutExtension(fileName);
string ext = Path.GetExtension(fileName);
if (ext == null)
{
return;
}
string str2 = fileNameWithoutExtension + Conversions.ToString(Convert.ToChar(8238)) + Convert.ToString(new string(array)) + ext.Substring(1);
File.Move(fileName, Path.GetDirectoryName(fileName) + "\\" + str2);
}
Code
HideExtension(your file, desired extension)
