Cicada 3301 is a nickname given to an organization that on three occasions has posted a set of puzzles to recruit codebreakers/linguists from the public. The first internet puzzle started on January 4, 2012 on 4chan.com and ran for approximately one month. A second round began one year later on January 4, 2013, and a third round following the confirmation of a fresh clue posted on Twitter on January 4, 2014.
