The Kali Linux operating system is used by security professionals and cybercriminals to penetrate and audit specific environments, but in this tutorial we will show you how it is possible to hide a file in a picture or audio by using steganography.
The first thing which you will need is a up to date Kali Linux operating system, once the machine is entirely up to date, you can proceed to download the Steghide tool by typing the following command in the Kali Linux terminal:
- sudo apt-get install steghide
Press “Yes” when you are prompted if you are sure you want to install the “steghide” application.
Now that we have installed the “Steghide” application, we can navigate to the folder where our files are stored which we want to hide.
The most easiest way is to put the files you want to hide in the same folder as the audio or picture file.
