Which of the following is a benefit of using steganalysis techniques in forensic response?

Show Suggested Answer Hide Answer
Suggested Answer: D

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 helpforensic 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.

I agree, D is the right choice. Steganalysis is all about detecting hidden data, and that's exactly what the question is asking for.

D seems like the clear answer here. Identifying the least significant bit encoding in a .wav file is a classic steganalysis technique used in forensics.
