This is not just a photo. You see a picture of a sunset or a cute cat. But inside the pixels, hidden where the human eye cannot see, is a Secret Message or even a Computer Virus. This art is called Steganography.
– Encryption: Scrambles the message so you can't read it (like a locked box). – Steganography: Hides the message so you don't even know it exists (like a false bottom in a suitcase).
The "Least Significant Bit" (LSB) Digital images are made of pixels. Each pixel has a color value. Hackers slightly change the color of the last bit of every pixel. – Result: The image looks 100% identical to the naked eye, but the computer reads the hidden code inside.
– Attack: They post a funny meme on Twitter (X). – Payload: The meme contains hidden commands that wake up a virus already sleeping on your PC. The antivirus ignores it because it's just a JPEG.
We use Steganalysis tools that look for statistical anomalies in the image file. – Lesson: In the digital world, trusting your eyes is not enough.
