In this diary, I'll show you a practical example of how steganography is used to hide payloads (or other suspicious data) from security tools and Security Analysts' eyes. Steganography can be defined like this: It is the art and science of concealing a secret message, file, or image within an ordinary-looking carrier—such as a digital photograph, audio clip, or text—so that the very existence of the hidden data is undetectable to casual observers (read: security people). Many online implementations of basic steganography allow you to embed a message (a string) into a picture[1].
