Cicada 3301 is less of an active website today and more of an internet history legend. In 2012, an anonymous entity dropped a cryptic black-and-white image on 4chan asking for high-IQ individuals, launching a three-year global scavenger hunt filled with steganography, darknet links, and physical clues taped to light poles around the world.
While the official puzzles are long dead and key portions remain unsolved, your teen is far more likely to encounter Cicada 3301 through mini-documentaries on YouTube than by trying to solve PGP ciphers directly. It is a fascinating study in cryptography and online subculture, provided they stick to retrospective video breakdowns rather than chasing copycat links into dodgy forums.
