Cicada 3301 (2012-2017)
eventCrypto & Digital ID
An anonymous internet puzzle so hard it worked as a global talent scout — and no one has ever proven who ran it.
Who they are
Cicada 3301 — a cryptographic puzzle series that first appeared January 4, 2012.
What they do
Multi-stage challenges in cryptography and steganography, explicitly aimed at recruiting 'highly intelligent individuals.' Its 2014 book, Liber Primus — 75 pages in an invented runic script — is still mostly undecoded.
How it works
Every genuine message was signed with one PGP key (7A35090F); the last verified message came in April 2017. Who ran it — a state, a company, independents — has never been established, and the engine leaves that open.
Why it matters
It's the digital form of an old pattern the engine already tracks: the invisible college, finding its people by test rather than by invitation.
The engine's record — word for word
Multi-stage cryptographic puzzle series first posted January 4, 2012, stated purpose: recruiting 'highly intelligent individuals' with cryptography/steganography/security skill. All genuine communications authenticated by OpenPGP key 7A35090F; the 2014 round released Liber Primus, a 75-page book in the custom Gematria Primus runic script, majority still undecoded; last verified signed message April 2017. The digital, gamified form of the invisible-college talent-sorting pattern — attribution unknown and HELD OPEN (state, private, or independent). [Report #178]
