Which of the following is a benefit of using steganalysis techniques in forensic response?
A . Breaking a symmetric cipher used in secure voice communications
B . Determining the frequency of unique attacks against DRM-protected media
C . Maintaining chain of custody for acquired evidence
D . Identifying least significant bit encoding of data in a .wav file

Answer: D

Explanation:

Steganalysis is the process of detecting hidden data in files or media, such as images, audio, or video. One technique of steganalysis is to identify least significant bit encoding, which is a method of hiding data by altering the least significant bits of each byte in a file. For example, a .wav file could contain hidden data encoded in the least significant bits of each audio sample. Steganalysis techniques can help forensic responders to discover hidden evidence or malicious payloads. Breaking a symmetric cipher, determining the frequency of attacks, or maintaining chain of custody are not related to steganalysis.
