In 2012, a series of complex puzzles appeared on the website known as 4Chan. Thousands took to the forums, trying to crack the codes and riddles written by an author known only as Cicada 3301. Some believed the puzzles were a recruitment tool for an unknown organization, others said they were part of a global cult. And while few have seen behind the curtain, even those who have solved the puzzles still aren’t sure who or what Cicada 3301 is – or what their ultimate goals are.
