Steganography, the technique you’re about to learn is all about hiding any confidential information behind another other file/photograph in a way that no newbie could understand. How does this work? basically via the command prompt, the hacker types a simple command and copies the actual data behind an image. Unless the victim is aware of the fact that the actual information can unencrypted by means of opening the file with some other application, he will be presented with the fake data. The technique is explained in the video attached below and all you need to have is Winrar or any other archive manager installed on your system.
