Ohai friends and neighbors,

Recently a few Games/Challenges/Cryptic Messages appeared on
several channels on the internet which are well-known for
attracting all sorts of alternative netizens and dwellers of
the deep web. While these challenges have no confirmed author
or goal several groups and individuals are making large efforts
to break these encrypted messages and solve the riddles. I would
like to introduce two of them: "Cicada 3301" and "Charlie one Umbra"
and try to reconstruct some of the methods used.

Greets,

MiKa
