File Extension Spoofer (FES) by AjuL Inc

Okay, basically you want to try to run a malicious software, something nasty, on someones computer and you don’t want to send over a executable but an image!  I believe many of you have went to distance to find this solution, some even tried a shortcut option for it and compress it in a rar.  Okay here’s the tool by AjuL from ajulinc.org and it’s called File Extension Spoofer.  How great this works, I have no idea as I don’t run .NET 4.0 and above on any of my stations.  Check out how it works.
