Cicada 3301 is the name given to eight sets of puzzles posted under the name "3301" online between 2012 and 2014. The first puzzle started on January 4, 2012,[1] on 4chan[2] and ran for nearly a month. A second round of puzzles 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.[3][4] The third puzzle remains unsolved. 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.[5][6] Cicada 3301 posted their last verified OpenPGP-signed message in April 2017, denying the validity of any unsigned puzzle.
