ARunning 'rm' command on the mounted image to list JPEG files
BMounting the disk image with write permissions and copying files
CEditing the disk image directly with a hex editor to extract files
DUsing 'photorec' to recover files from the disk image
Step-by-Step Solution

  1. Step 1: Identify a non-destructive tool

    Tools like 'photorec' scan disk images for file signatures without altering the image.

  2. Step 2: Avoid mounting with write permissions

    Mounting with write permissions risks modifying the image, which is not acceptable in forensic analysis.

  3. Step 3: Avoid manual hex editing for extraction

    Manual hex editing is error-prone and inefficient for extracting multiple files.

  4. Final Answer:

    Using 'photorec' to recover files from the disk image -> Option D

    Non-destructive file recovery tool chosen [OK]
Quick Trick: Use file recovery tools that don't alter disk images [OK]
