質問 # 97
What is the steganography anti-forensics technique?
正解：D
解説：
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.
