Steganalysis hides in media or a file.

Identifying least significant bit encoding of data in a .wav file is a benefit of using steganalysis techniques in forensic response. Steganalysis is the process of identifying and detecting steganography, which is the practice of hiding data within other data to conceal its existence. By using steganalysis, forensic investigators can analyze digital media to detect hidden data and information. In the context of forensic response, identifying least significant bit encoding of data in a .wav file can help investigators find hidden messages or files that may be relevant to an investigation.

D. Identifying least significant bit encoding of data in a .wav file is a benefit of using steganalysis techniques in forensic response. Steganography is the practice of concealing information within another file, such as hiding a message within an image or an audio file. Steganalysis is the process of detecting the presence of hidden information. By using steganalysis techniques, forensic analysts can identify the least significant bit encoding of data in a .wav file and determine if it contains hidden information. This can be useful in identifying whether a file has been manipulated or tampered with, and can provide valuable evidence in forensic investigations.

B. Steganalysis attempts to identify messages and/or media which have been hidden in cover files.

Least Significant Bit (LSB) encoding is a common steganography technique where the least significant bits of digital media files (such as .wav audio files) are altered to embed hidden data. Steganalysis techniques are specifically designed to detect such hidden data by analyzing these subtle changes, making it a direct application of steganalysis in forensic response.
