What is Steganography?
Steganography is the practice of concealing a message within another message or physical object, so its presence is not apparent to an observer. It's a method of hiding information, making it a form of covert communication. Unlike cryptography, which scrambles the message, steganography aims to hide the very existence of the message itself

How hackers use it to hide viruses, trojans, and malware.

Real-world cyber security risks.

“What is LSB (Least Significant Bit)?”

"One of the simplest ways to hide data in an image is called LSB, or Least Significant Bit steganography."

"Every image is made up of pixels — and each pixel has 3 values: Red, Green, and Blue. Each color value is a number between 0 and 255, stored in 8 bits."

"Changing the last bit of that 8-bit value doesn’t noticeably change the color — but we can use it to store secret information."

Pixel Color Binary Last Bit New Bit
Red = 10110100 Ends in 0 → Change to 1 10110101

(R, G, B) → (180, 100, 200) Looks the same to the eye Hidden bit inside


"So by changing the last bits of many pixels, we can hide entire files — even though the image still looks the same."


sudo apt install steghide
steghide embed -cf cover.jpg -ef secret.txt -sf stego.jpg -p pass
steghide extract -sf stego.jpg -p pass -xf output.txt



echo "This is my hidden message for YouTube demo" secret.txt

# Embed the secret message into the image
steghide embed -cf bg.jpg -ef secret.txt -sf stego.jpg -p mypass

# Extract the message from the stego image
steghide extract -sf stego.jpg -p mypass -xf extracted.txt

cat extracted.txt
