putting in the same URLs, I can't get the page to load at all. First site is gone now entirely and the second one is only a blank page.
I'd be surprised of the program wasn't a .NET Executable. It seems oddly common to use a .NET program for this sort of thing.
It's actually quite common to post such programs as "tools" or "utilities" on game forums. It's common for Minecraft, for example, a user will post tools claiming to give the person full admin access to any server, for example, then steal private information. The fun part is that since they are .NET they are fairly easy to decompile; and while the more clever ones will encrypt the password it's dead-simple to just remove the decryptor and run it separate from the malicious software to get things like E-mail passwords, as they need to have SMTP passwords in the file to send their sweet sweet private info to. In one case the user had even used their own personal E-mail, (connected to paypal, amazon, Steam, Facebook, etc.) so I went ahead and E-mailed his family members from his account confessing some rather questionable feelings. Let's just say things must have been VERY awkward between himself and his sister for a while.
