Hide Sensitive RAR Files in Images

 

12. Hide Sensitive RAR Files in Images

CMD facilitates a command which lets you concatenate or fuse two files into a single file. While this command comes in handy in merging the contents of basic file types such as TXT or CSV, you can also use the command to hide a RAR, ZIP, or another archived file inside an image or text file. To achieve this, follow these steps:

• Open CMD in the directory which contains both files using the 10th item in this list or use the cd command to change the directory
• Use command copy /b <RAR_filename>.rar + <image_filename>.<extension> <result_filename>.<extension>. In our case, we used copy /b modules.rar+wave.png test2.png 

Note: make sure you enter the RAR file first followed by the other file, else you won’t be able to recover the RAR package. The method also works on most common file types including documents and PDFs as long as you add the archive file first.

• This will generate the result file, which in our case is test2.png

This PNG file displays as a normal image filebut when you open it with WinRAR or any other extraction tool, it will extract the RAR file which is buried under the image file. This is a good way of saving your sensitive files from curious friends or co-workers or even prevent them from being misused even in case of a data breach.
