Understanding Cicada 3301: The Iconic Alternate Reality Game

From Wikipedia: Cicada 3301 is a nickname given to three sets of puzzles posted under the name "3301" online between 2012 and 2014.[1] The first puzzle started on January 4, 2012, on 4chan and ran for nearly a month. A second round began one year later on January 4, 2013, and then a third round following the confirmation of a fresh clue posted on Twitter on January 4, 2014.[2][3] The third puzzle has yet to be solved. The stated intent was to recruit "intelligent individuals" by presenting a series of puzzles to be solved; no new puzzles were published on January 4, 2015. A new clue was posted on Twitter on January 5, 2016.[4][5] Cicada 3301 posted their last verified OpenPGP-signed message in April 2017, denying the validity of any unsigned puzzle.[6] The puzzles focused heavily on data security, cryptography, steganography, and internet anonymity.[7][8][9] It has been called "the most elaborate and mysterious puzzle of the internet age",[10] and is listed as one of the "top 5 eeriest, unsolved mysteries of the internet" by The Washington Post,[11] and much speculation exists as to its function. Many have speculated that the puzzles are a recruitment tool for the NSA, CIA,[12] MI6, a "Masonic conspiracy",[13] or a cyber mercenary group.[1][7] Others have stated Cicada 3301 is an alternate reality game, although no company or individual has attempted to monetize it.[10] Some of the final contestants believe that Cicada 3301 is a remnant of the late 1980s and 1990s Cypherpunk movement.[14] Dark Web: Cicada 3301, a film inspired by the organization, was released in 2021.
