- Audio Steganography.
- Network Steganography.

Do you see steganography as a good thing?
Those responsible for the security of companies and institutions do not need to hide their communications. To keep them safe, cryptography is enough. Steganography is a tool of great interest for different types of criminals, since it allows communication without being detected.
What is an example of steganography?
Steganography Examples Playing an audio track backwards to reveal a secret message. Playing a video at a faster frame rate (FPS) to reveal a hidden image. Embedding a message in the red, green, or blue channel of an RGB image. Hiding information within a file header or metadata.

Why is steganography bad?
In contrast to cryptography, which scrambles a message so it cannot be understood steganography hides the message so it cannot be seen. A message in ciphertext may arouse suspicion on the part of the recipient but an “invisible ” message created with steganographic metho ds will not.
Why would a hacker use steganography?
Why? Hackers are able to use image steganography techniques to conduct malicious activity and ultimately compromise enterprise networks. Today, hackers use steganography to obfuscate payloads embedded inside of the image that can be undetectable by traditional security solutions and successfully spread malware.
How do you decode steganography?
To decode a hidden message from an image, just choose an image and hit the Decode button. Neither the image nor the message that has been hidden will be at any moment transmitted over the web, all the magic happens within your browser.
