How Hackers Hide Secret Messages in Audio Files | Audio Steg Google CTF (BEGINNER'S QUEST)

In this video, I solve an Audio Steganography CTF challenge called "Audio Steg" from Google CTF (BEGINNER'S QUEST) — and explain every step in a way that's friendly for complete beginners. We're given a WAV audio file with a hidden flag inside. Using Python and a bit of knowledge about how audio data is stored, we extract the secret message hidden in the Least Significant Bits (LSB) of the file's raw bytes. 🔍 What you'll learn: → What steganography is and how it differs from encryption → Common audio steganography techniques (LSB, spectrogram, phase encoding) → How to analyze a WAV file with Python → The difference between sample-level and byte-level LSB encoding → Why tools like steghide didn't work — and how to write your own extractor → How to generate and read a spectrogram 🛠️ Tools used: → Python (wave, numpy, scipy, matplotlib) → steghide → Terminal / Bash 📢 New to CTFs?
