WhiteSpace Warfare - 500 An old intelligence officer used to hide secrets in plain sight - not with ciphers, but with silence. His final message looks ordinary, but those who know how to look can see patterns between the letters… invisible marks that speak louder than words
I'll analyze this steganography challenge that hints at hidden data in whitespace characters.
