In steganography, the carrier is the file or medium used to hide the secret message. In this example, the sound file is the carrier because it contains the hidden message embedded using the least significant bit method.

This includes verifying seizure procedures and documenting the status of the device before any interaction.

Turning the computer on prematurely risks altering or destroying volatile data.

Making a forensic copy (imaging) can only happen after proper documentation and preservation steps.

Photographing the desktop is relevant only after power-on but only if approved and documented.

This process aligns with NIST guidelines (SP 800-86) and the Scientific Working Group on Digital Evidence (SWGDE) principles emphasizing preservation and documentation as foundational steps.
