It's the group that posted those weird puzzles in 2012 on 4chan...

"The puzzles focused heavily on data security, cryptography, steganography, and internet anonymity."

"It has been called "the most elaborate and mysterious puzzle of the internet age" and is listed as one of the "top 5 eeriest, unsolved mysteries of the internet", and much speculation exists as to its function.

" The stated purpose of the puzzles each year has been to recruit "highly intelligent individuals", although the ultimate purpose remains unknown "

" The first puzzle, of 2012, has been solved by Marcus Wanner. According to him, those who solved the puzzles were asked questions about their support of information freedom, online privacy and freedom, and rejection of censorship.
