These days companies are given more power to monitor emails and to examine your personal files. And with more and more malicious ‘spy’ software being widely used, you need to be sure that files containing sensitive information are kept safe from prying eyes. Electronic privacy is no longer guaranteed – who knows who might be intercepting your emails or scanning your hard drive without your knowledge or consent?

This is an example of a theory on how you can bypass that restriction. You could create a picture file that looks and behaves exactly like any other picture file but contains hidden encrypted files, or you could hide a file inside a Word document that would not attract attention if discovered. Such files can later be safely extracted. This is in theory. Here’s the practical part of doing it.



Camouflage allows you to hide files by scrambling them and then attaching them to the file of your choice. This camouflaged file then looks and behaves like a normal file, and can be stored, used or emailed without attracting attention. For additional security you can password your camouflaged file. This password will be required when extracting the files within. You can even camouflage files within camouflaged files for double encryption.

Here’s the test I did with Camouflage.
I created 3 text files, test1.txt, text2.txt and text3.txt. I use my mouse to select all three files, right click and choosed “Camouflage“.

A dialog box will popup and will list down all the files I’ve selected to camouflage.

After clicking next, it ask me to select a file that will display when ran. So I chose an image file called camouflage.gif.

Next is the location and filename that I’d like to save the new camouflaged file. I had to enter a new name called camouflageNEW.gif in order not to overwrite my original camouflage.gif image.

And finally you can choose to enter a password to protect your camouflaged files. This password is for uncamouflage your camouflaged files.

Once I clicked finish, I noticed that there’s a new file generated called camouflageNEW.gif. I ran that file and it only displays the image file. What about the 3 text files which I’ve embedded into that image file? It’s in there. To extract the 3 text files, just right click on the camouflageNEW.gif and select “Uncamouflage“. Enter the password and a dialog box will appear with all 3 text files listed for you to extract.

This technique is not new. I’ve read somewhere on the Internet that terrorist actually uses this technique to send messages across. I’ve hexedited the camouflaged file and couldn’t find the password I entered and also the 3 text filenames. It’s pretty safe but I believe that there is surely a way to disassemble the camouflaged files without knowing the password. Perhaps a scanner can be done. But before doing that, you must know how camouflage works.
