Cicada 3301

Cicada 3301 was a name given to a secret unknown organization that posted a series of nearly-unsolvable games and riddles online, and is believed to have been an attempt to recruit highly-advanced codebreakers and linguists. Their puzzles focused heavily on data security, cryptography, and steganography and are dubbed one of the ‘Top 5 Eeriest, Unsolved Mysteries of The Internet’ by The Washington Post.

Many have speculated that the NSA, CIA, MI6 or Freemasons are involved. While a few anonymous individuals have stepped forward claiming they had completed the process, they did not divulge any information and the organization has yet to confirm their claims.
