Steganography is an art of hiding messages covert way so that exclusive the sender and recipient know the original message.This technique permits sender and receiver to communicate secretly and the third party won’t mindful of the correspondence happen.

Steganalysis is the process of recovering , It decides the encoded hidden message, and if conceivable, it recovers that message.The message can be identified by taking a gander at changes between bit designs and unusually large file sizes.This is considered to be an attack on the covered information.

In this Kali Tutorial, we show how to use the tool that uncovers hidden data from the image file.

One of the problems that we have these days is that there are not a lot of tools that include steganalysis modules, so it is a little difficult to protect our networks from this kind of attacks. There are different tools for steganalysis but almost all of them require a person to manually use them.
