How Hackers Hide Files Inside Images (Steganography Explained)

Ever wondered how files can be hidden inside images without changing how the image looks?
In this video, I explain steganography attacks from a cybersecurity perspective and show a safe, step-by-step demonstration of how data — including executable files — can be embedded and later extracted from image files.

This video is focused on education, awareness, and ethical hacking concepts, helping you understand how steganography works, who uses it, why it’s used, and how defenders detect it.

Using a popular open-source tool called OpenStego, I demonstrate:

How files are hidden inside image files

Why opening the image alone does nothing

How password-protected hidden data is extracted

The difference between data hiding and code execution


Whether you’re a beginner in cybersecurity, an ethical hacker, or someone interested in digital forensics, this video will give you a clear and practical understanding of steganography.
