How to Hide a Secret Message in an Image File

Have you ever wondered how Terrorist are communicating behind the scenes?  Below I will show you one popular method  by adding a message into an image that no one will see unless they know where to look.

First: You will need two files, an image and a text file with your hidden message.

Next: Open up your command prompt.   Go to your start menu and click on Run, type in cmd and  press enter. You should now see something similar to the image illustrated below.

    cmd1

Next: For the purpose of this demo I have placed the image file (test.jpg) in the root of my C drive. Type cd\ and press enter. You should now see something similar to the image illustrated below.

    cmd2

    Next: Now for the fun stuff, place both of your files (i.e test.jpg and your hidden message test.txt) in the root of your C drive. Type in the following command copy /b test.jpg + test.txt result.jpg and press enter. You should now see something similar to the image illustrated below.

    cmd3

    Finally: You will now see that that the command created a new file named result.jpg, my outcome file is below. Can you find the hidden message? To see the hidden message open the image up in word pad and scroll to the very end.
