.NET [Snippet|Tutorial] Extension Spoofer [Snippet|Tutorial]

First thing is first, all credits to Aeonhack for his theme used in this program.

The reason I call this a snippet is because many people include these types of programs in their keyloggers, file binders, crypters, and more.

To make this program (my way), you'll need:
- Three Textboxes
- Two Buttons

The first button will select the file to be spoofed

Code 
Dim browse As New OpenFileDialog

browse.Filter = "Executable Files|*.exe|All Files|*.*"

browse.ShowDialog()

TextBox1.Text = browse.FileName

'Declares a new open file dialog, and filters the extension to executable files or all files

'The first textbox will be the executable's name that was previously chosen

This will allow you to select the file to be spoofed.

The second button will simply rename your file, but in a special way
***Note: The code here looks messed up because of the left to right overdrive character, but in visual basic this will look normal***

Code 
My.Computer.FileSystem.RenameFile(TextBox1.Text, TextBox2.Text & "‮" & StrReverse(TextBox3.Text) & ".exe")

'Renames the file from the "browse" open dialog

'The new name is the second textbox, the "" appears to be nothing, but it's the Left To Right Overdrive Character

'The String Reverse function puts the file extension backwards (appears forward)

'Lastly, the file is really saved with the .exe extension

Here is a look at the program itself:

** JIT Debugging **

To enable just-in-time (JIT) debugging, the .config file for this

application or computer (machine.config) must have the

jitDebugging value set in the system.windows.forms section.

The application must also be compiled with debugging

enabled.



For example:



<configuration>

    <system.windows.forms jitDebugging="true" />

</configuration>



When JIT debugging is enabled, any unhandled exception

will be sent to the JIT debugger registered on the computer

rather than be handled by this dialog box.
