Description: I hid real 100$ in a YouTube video and challenged people to find it. Whoever finds it first, gets to keep it. The challenge was finally solved after 3 days since the video was released. This video explains how to solve this challenge and how to find the 100$ hidden in the video. Watch the video with hidden 100$: youtu.be/Ua7C1v4Yquo Writeup written by the winner: hong5489.github.io/2022-02-19-techraj-challenge I used a concept called steganography to hide a secret message in the video that helps claim the gift. Steganography simply means hiding data in something that is in plain sight, like in an image, video or audio. If you want to learn more about Steganography and the LSB algorithm, watch this video I made: youtu.be/_KX8ORUA_98 I also used audio spectrogram tricks to hide a secret key that can be used to decrypt the hidden message in the video. The code to solve this challenge is available on GitHub: github.com/teja156/100-dollar-challenge-scripts/blob/main/decode.py Thanks for watching! SUBSCRIBE for more videos.
