Hackers Hide Messages in Images & Files 🖼️

In this video, we’re breaking down steganography. What it is, how it works, and why hiding data inside ordinary files is more powerful than most people realize. I walk through the core concept of embedding secret information into images using least significant bit (LSB) manipulation, explain how pixel data is stored in binary, and demonstrate how tiny bit flips can carry entire hidden messages without changing how an image looks.

You’ll also see a hands-on walkthrough using Steghide to embed and extract a secret file from a Linux image, including how passphrases add an extra protection layer. Then we shift to hiding data in plain text using StegSnow, where invisible trailing spaces and tabs become storage for concealed information.
