Welcome back to the Rabbit Hole, the series where we follow one weird internet thread until it’s 2 a.m. (Last time it was the Elisa Lam elevator video.) This week’s thread starts with a cicada.
4 January 2012
Someone posts a plain image on 4chan. White text on black: it says they’re looking for highly intelligent individuals, that there’s a message hidden in the image, and that it’s signed “3301.”
People assumed it was a prank. Then they opened the image in a text editor and found a hidden message. Which led to a URL. Which led to a cipher. Which led to a phone number. Which, when you called it, played a recording that led to… more puzzles.
The trail used book codes, old poems, prime numbers, and a Mayan numeral system. Then it left the internet entirely. Coordinates pointed to real posters stuck to lampposts in cities across the world, from Warsaw to Seoul to Sydney. Each poster had a cicada and a QR code.
“We want the best, not the followers”
After the posters, the puzzle split. A few solvers got private messages and vanished from the public forums. The rest got a message saying the group had found the people it was looking for, and the round was over.
It happened again in January 2013 and January 2014. Each year, harder.
The Liber Primus
The 2014 round ended with a book. Fifty-eight pages, written in runes, called the Liber Primus (“the first book”). A few pages were decoded early and read like a mix of philosophy and instructions. Most of it has never been cracked. Ten years on, people are still at it on Discord servers and subreddits, and progress has basically stalled.
Nobody who was “recruited” has ever credibly said what happened next. Which is either very impressive discipline or proof that nothing happened at all.
So who was behind it?
The fun theories first:
- A spy agency (NSA, CIA, GCHQ) hunting for codebreakers. Plausible-ish, except agencies don’t usually recruit via 4chan.
- A cypherpunk group building a privacy movement. This fits the content of the decoded pages best.
- A bank or tech company doing a very elaborate hiring stunt. Boring, but 2012 was peak “viral marketing.”
- One very dedicated person. Honestly, my favourite.
In 2015, a mysterious note in Cicada’s verified signature warned that everyone claiming to be Cicada 3301 was fake. Which, of course, made people trust the warning and the fakes.
Why it still works on us
What gets me about Cicada is the same thing that got me about the Elisa Lam video, or the Max Headroom hijacking: the mystery is the content. The puzzle doesn’t need a crime, a body, or a villain. It just needs the feeling that somewhere, someone knows the answer and isn’t telling.
And the book is still sitting there. Unread.
Would you have called the phone number? I absolutely would have. Comments are open, fellow sleuths.
