Hackers Hide Messages in Images 🖼️

In this video, I break down steganography — the technique of hiding information inside of an object, like a picture. Unlike encryption, which makes data unreadable, steganography conceals the existence of the message entirely. That means a simple image, audio file, or document could secretly contain hidden data without changing how it looks.

In this video, I cover:

- What steganography is (and how it differs from encryption)
- How hidden data is embedded inside images using pixel values
- A live demo of hiding a message inside an image file
- Real-world use cases
- Why steganography is so difficult to detect
