How To Hide Files NOT Steganography

privateinvestigator

So you have some files, music, video, or anything you wanna hide from folks for whatever reason? Well, here’s an easy solution that does a good job of hiding stuff without you having to encrypt the data or spend any loot.

You will need a zipping program to accomplish this. There are many open source zipping tools on the web such as WinZip, WinRAR, 7-Zip, etc. Just grab one of those and you’re good.

What makes this work is that images are read from the header down, whereas Zip files are read from the footer up. This enables you to merge the files and no one will ever know that your “secret stuff” is, in essence, hidden right inside the picture. GIFs work best, but JPGs and other file types should work just as well. In this example I will be using a .jpg – my company logo (I’m a shameless plugg’r, grossly incorporating ME into everything…;). Now onto the process…

The first thing you will need to do is select a picture to be your container. Again, I chose my the Victory Investigations logo. Then collect the files you would like to hide.

Once you’ve done this, you’ll need to create a folder on the hard drive like so:

haddrive

Place all of the files you want to hide AND the container picture inside that folder.

Next, using your zipping program, zip the files you want to hide as seen here:

archive

The contents of your folder should look like this now:

As you can see, I’ve chosen the name of my zipped file to be “STAYOUT“.       Yeah, I know, cheesy, right?

Now the real fun begins…

You need to access the command prompt. You can do this a couple of ways. One, click Start then type “Run“, without the quotes. Then Type “CMD” without the quotes and the command prompt will appear. OR hold down the Windows and “R” keys on your keyboard, then type “CMD” without the quotes. Either way will get to the Command Prompt. At this time, you should have a window appear like so:

cmd3

Now you have to drill down to the directory where your file is located. At the prompt type cd\ to get to the root directory. Then type cd and the name of the directory where the files are located (in this case it’s “There’s Nothing Here”).

cmd4

The next thing you need to do is type the following (of course, replace the file names I chose with the names you have chosen):

copy /b Container.JPG + STAYOUT.rar Container.jpg

Now the command prompt should look like this:

cmd6

AND VOILÀ!

You can check the properties of the container picture before you add the secret files and after hiding them and you’ll see that the size has increased by the amount of the added files.

You can now access your hidden files in two ways. Firstly, simply change the extension to .RAR and open the file using WinRAR. Secondly, you can just right-click on the JPEG image and choose Open With and then scroll down to WinRAR. Either way, you’ll see your hidden files show up that you can then extract out.

Please note:  this is ONLY one way of hiding files. I know there are other ways and even different procedures to accomplish what I’ve demonstrated here. 

Also realize that this method, in no way, protects your data from folks like myself – private investigator and digital forensic specialist.
