In this case, the S-Tools tool is used. We will also use a custom python script to help us analyze the images bit by bit in search for hidden information. Lastly, we will also perform a histogram analysis, coding another custom python script.</p> <p>S-Tools is a very powerful tool developed by Andy Brown. It allows you to hide messages using steganography in BMP, GIF, and WAV images. It is a very simple tool that allows drag-and-drop to process the relevant files. Additionally, it can encrypt the hidden information so that even if the message is discovered, the information cannot be decrypted without the password.</p>
