Cicada 3301: The Internet’s Most Mysterious Puzzle and Nobody Knows Who Made It
On January 4 2012 a message appeared on 4chan — one of the internet’s most chaotic forums — that was unlike anything posted there before. It claimed to be looking for highly intelligent individuals. What followed was a three year puzzle spanning cryptography, steganography, ancient literature, physical locations on five continents and a mysterious organisation that has never been identified. Cicada 3301 remains the most elaborate and most baffling puzzle in internet history.
