Extract hidden metadata from Files with ExifTool

Configurare noua (How To)

Situatie

Ever wonder what hidden info might be lurking inside an image or document? Many files store metadata—like camera details, GPS coordinates, timestamps, and even usernames—without the owner realizing it. With ExifTool, you can pull out this data in seconds.

ExifTool is a command-line tool used to extract, analyze, and modify metadata in files like images, PDFs, and videos. Metadata includes hidden details such as:

  • Camera info (model, lens, settings)
  • Timestamps (creation, modification dates)
  • GPS coordinates (where a photo was taken)
  • Software used (Photoshop, MS Word, etc.)

It’s pre-installed in Kali Linux and widely used in digital forensics, OSINT, and privacy audits.

Solutie

Steps:

  1. Check if ExifTool is installed (it’s built into Kali):

    exiftool -ver
  2. Extract metadata from an image or document:

    exiftool file.jpg
  3. Look for interesting details like:

    • Device Info: Camera model, software used
    • Timestamps: When the file was created/modified
    • GPS Data: Location where the photo was taken

    Example output:

    Camera Model: Nikon D3500
    GPS
    Latitude: 48.8584°
    GPS
    Longitude: 2.2945°

    Software: Adobe Photoshop 2023
  4. Remove metadata before sharing a file:

    exiftool -all= file.jpg

Why this matters: Photos and documents can leak personal info without you knowing. This tool helps you analyze potential leaks or clean files before sharing them.
