Steganography

Appended data and carving

Chapter 3 of 6 · Steganography 50%

🧩 The Cicada 3301 puzzles (2012-2014) hid clues inside ordinary images that scanned past where any viewer stops reading. Could you carve out what is glued onto the end of a picture?

A picture can open perfectly and still carry a full ZIP glued past its end marker. You'll read the byte that says 'stop here', then carve the hidden archive out with binwalk and dd. Malware uses this exact trick to slip past file filters. 🔍
