Steganography is the anti-forensics technique of hiding malicious content within seemingly innocent
files, such as image, audio, or video files. The goal is to conceal data or code in a way that avoids
suspicion and detection, thereby making traditional security inspection tools ineffective unless they
are explicitly designed to detect hidden data within media files.
Steganography differs from encryption because it does not simply make data unreadable; it hides the
existence of the data itself. It is commonly used in cyber operations to hide command-and-control
instructions or to exfiltrate sensitive information in covert ways.
