Cicada 3301: An Internet Mystery

On the 4th of January, 2012, a user on 4chan
posted this image
to the site’s infamous /b/ or random board.
The anonymous author, who went by the four-digit
pseudonym 3301, challenged users to uncover
a message hidden within the image.
Unbeknownst to those who stumbled across it,
someone had just set in motion one of the
most elaborate scavenger hunts the internet
has ever seen.
Within minutes of the image being posted someone
discovered that by opening the file using
a text editor an appended string of readable
text could be found.
The string contained a cipher that, once deciphered,
formed a link to yet another image.
At first this appeared to be a dead end but
using an application known as OutGuess
users were able to extract hidden information embedded
within the first image.
The extracted information lead to a subreddit
which in turn contained information about a book.
The book along with a code could
then be used to uncover a
phone number that, when called,
played this prerecorded message.
By the following day, the initial image had
been reposed all over the internet.
A growing community of armchair detectives
sought to unravel this elaborate puzzle but
no one was quite sure what to make off it.
What was the puzzle for?
Who was behind it?
What happens when you reach the end?
Some naturally dismissed it as an elaborate
joke while others perceived its complexity
as evidence against it being the work of a
mere troll.
Before long, rumors began to circulate that
this could be the work of some secret society
or intelligence agency with the intent of
recruiting individuals proficient in
cryptography, steganography,
and other related fields.
Of course, it was nothing but a rumor.
The two missing numbers mentioned in the recording
proved to be the dimensions of the original image.
After multiplying the width and height with
3301 and using the product as a web address,
users were taken to a website.
The website consisted of a countdown as well
as an image of a cicada.
When the countdown reached zero, the page
was updated with a list of coordinates.
The coordinates pointed to locations around
the globe.
14 locations in 5 different countries.
It was now up to participants living near
the specified coordinates to rise from their
comfortable armchairs and venture outside.
Those who believed Cicada to be the work of an
organization now felt their beliefs had been justified.
In their opinion, only some international
collective possessed the means and resources
to create a scavenger hunt of this magnitude.
This was not the work of your average troll.
No, this had to be something else.
At each location was a poster with the cicada
symbol and a QR code.
…on the bike shelter over here.
See I got it… I got it right there.
You can see the corners, I just kinda ripped it off.
The codes linked to an image, the image contained
a riddle, the riddle lead to a book,
and the book lead to a website.
But here, the puzzle took an unexpected turn.
Only a select group of first arrivals to this website
were accepted into the final stage of the puzzle.
The site eventually closed down with the message:
“We want the best, not the followers.”
The finalists were also warned not to collaborate
with others nor to share the details of this
private stage of the puzzle.
Well, given that we know this, it’s safe to
say that not everyone heeded that warning.
But those who did presumably advanced through
the final stages before reaching the very
end of the puzzle.
After nearly a month of silence an image appeared
on the subreddit announcing the conclusion
of the puzzle and, just like that, the hunt
was over.
Cicada had supposedly found the
“highly intelligent individuals” they were looking for
and whatever happened to them is a bit of a
mystery but more on that in a moment.
The lack of an explanation was perceived by
many as confirmation that the puzzle had been
nothing but a wild-goose chase intent on wasting
everyones time.
After all, questions raised by the original
image remained unanswered.
What was the puzzle for?
Who was behind it?
What happens when you reach the end?
However, as it later turned out, this was
only the beginning.
Whomever was behind this intricate game had
the foresight to include an authentication
code known as a PGP signature
along with every clue.
This allowed users to verify that an image
or message was actually from Cicada as opposed
to some impostor seeking to derail or hijack
the puzzle.
Cicada had repeatedly warned of such “false paths”
and insisted that any message lacking
a valid PGP signature should promptly be disregarded.
That’s why this image, posted exactly a year
and a day after the first, provoked such a frenzy.
After a year of lackluster imitations, this
image finally matched the official PGP signature.
Cicada was back and it was time for round two.
The second puzzle was not too dissimilar from
the first.
The image enclosed a message, the message
lead to a book, the book produced a link,
and gradually the puzzle unfolded.
At one point, a recording titled
The Instar Emergence was uncovered.
Another clue lead to a cryptic Twitter account
which then lead to an image.
The image proved vital to the progression
of the puzzle but the inclusion of this runic
alphabet would remain a mystery for quite
some time.
Much like the first puzzle the second swelled
into the physical world when a list coordinates
compelled participants to, once again, take
to the streets in search of enigmatic posters.
This time it was
8 locations in 4 different countries.
But eventually the trail went cold once again.
Another select group of first arrivals had
been accepted into a final private stage of the puzzle.
Unlike the first puzzle the second did not
conclude with an official message from Cicada.
The trail merely went cold and Cicada vanished
once more leaving us no closer to an explanation.
However, this was still not the end.
At the beginning of 2014
it was time for round three.
Once again the image enclosed a message, the
message lead to a book, the book produced a link,
and suffice it to say, it was more
of the same.
Except, this time, the puzzle seemed to revolve
around a strange book.
The book was titled Liber Primus, meaning
First Book in Latin, and was evidently written by Cicada.
The runic alphabet uncovered in 2013 finally made
sense as the book was primarily written in runes.
Even so, the meaning of the translated pages
were cryptic at best.
The book consisted of various philosophical and
idealogical ideas and appeared to be their manifesto.
Many have since compared the strange writings
to that of a cult.
Nevertheless, the book also comprised a myriad
of clues and codes.
For example, this page advised participants
to seek out a website on the deep web
but the site remains undiscovered.
Another page lead to a website containing
yet another recording titled Interconnectedness.
However, a significant portion of the book
has yet to be translated.
The runic text on some of the pages appear
to be obfuscated by layers of encryption
that has yet to be decrypted.
Of the 74 pages featuring runes, only 19 have
been successfully translated.
As 2015 came and went without the launch of
a new puzzle, many came to suspect the Liber Primus
had to be completed if Cicada was to return.
This was more or less confirmed
at the beginning of 2016
when Cicada encouraged
a reexamination of the book.
More than four years have now gone by with minimal
progress and near complete silence from Cicada.
Questions raised by the original image have
gone ignored.
What is the purpose of these puzzles?
Who’s behind them?
What happens when you reach the end?
When the initial image appeared on 4chan back
in 2012 many assumed Cicada 3301 to be an
alternate reality game designed by a corporation
to promote a new service or product.
For example, Microsoft developed an elaborate
ARG back in 2001 to promote the film
Artificial Intelligence and a similar viral marketing
campaign was used to promote the release of Halo 2.
But the release of subsequent puzzles and
the complete lack of commercialization
has more or less eliminated that possibility.
If we choose to believe some of the leaked
information from the private end-stage of
each puzzle than we do gain some insight into
who this group might be.
For example, at the end of the first puzzle,
finalists supposedly received this email.
In it, Cicada describe themselves as an international
group who believe that privacy is an inalienable right.
The aim of each puzzle is to recruit
like-minded individuals
in an effort to develop
privacy-conscious solutions.
The email then concludes with three questions.
The PGP signature, which would have confirmed
the authenticity of the email, was conveniently
removed by the leaker.
If a version with a valid signature does exists
online I was unable to find it.
But regardless of it’s legitimacy, I find
this question a bit odd.
It reads:
“Do you believe that information should be free?”
Assuming the expected answer is yes then the
very first sentence…
…seems a bit hypocritical.
While the idea of a secret society recruiting
individuals by means of elaborate cryptographic
puzzles may seem a bit absurd or even conspiratorial,
it’s not entirely unfounded.
Corporations and governments alike have employed
similar recruitment techniques since at least
the second World War.
In 2013, the British intelligence agency GCHQ
launched a recruitment program known as
“Can You Find It?”.
Participants had to decrypt a number of cryptograms
hidden across the internet and those who managed
to solve the entire puzzle were offered a
prize or a position at the agency.
Google did something similar with enigmatic
billboards back in 2004 and the US Navy launched
a near-identical project in 2014.
Okay, but then, what about the recruits?
Why have we not heard from these chosen few?
Well, we have.
It’s just that separating a legitimate finalist
from an impostor is virtually impossible.
In a 2015 interview with Rolling Stone, two
alleged winners of the first puzzle chronicled
the events beyond the final stage.
After receiving an email from Cicada they
were taken to a forum on the dark web.
Here, they could communicate with some twenty
some odd recruits as well as a handful of
established members of Cicada.
They were told that Cicada 3301 had been founded
by a group of friends who shared common ideals
about security, privacy, and censorship.
The goal was to work as a collective to develop
software applications in line with that ideology.
As friends recruited friends, this secret
society quickly expanded into a decentralized
international organization.
The recruits were then tasked with developing
software that fit the ideology of the group
and members of Cicada would oversee their
But without the allure of a puzzle to be solved,
the recruits quickly lost interest.
By the end of 2012 all but one had left and
a few months later the site was gone.
They never heard from Cicada again.
One of the two winners, named Marcus Wanner, later
elaborated further in a video by YouTuber Nox Populi.
Furthermore, Nox Populi himself claims to
be a winner of the second puzzle so I reached
out to him and this is some of what he had
to say.
After completing the final stages of the second
puzzle Nox Populi received an invitation to
join Cicada 3301.
However, he was not invited to a website but
was instead merely told to be patient.
Then, around May of 2013, all communication
with Cicada abruptly ceased.
This was around the same time as when the
website dedicated to the winners of the first
puzzle was suddenly taken down.
Nox Populi later contacted other winners of
the second puzzle to compare notes and their
experiences were identical.
In his own words:
“All the stories were the same, we were invited
to join 3301, then something happened and
silence followed a request for patience.”
Nox Populi suppose that roughly five others
completed the second puzzle in contrast to
the twenty-odd winners of the first.
In regards to who or what Cicada is, Nox Populi
believes they could be a remnant of the cypherpunk
movement of the late 80s and 90s.
Essentially a small group of activists advocating
widespread use of strong cryptography and
privacy-enhancing technologies but he admits
that there is no way to know for certain.
If you want a far more comprehensive walkthrough
of these puzzles as opposed to my brief overview,
Nox Populi has produced a number of videos
on his channel which I highly recommend.
While these accounts cannot be verified they
do make for a very compelling argument as
to what Cicada is.
A group of anonymous developers seeking to
develop privacy-conscious applications by
recruiting talented individuals via cryptographic
Sure, it is not nearly as exciting as a shadow
government seeking world domination or any
of the more fantastical theories but it is
certainly more plausible.
You have to keep in mind that no part of these
puzzles would have required more than one person.
The posters are often pointed to as evidence
that this must be the work of some international
organization but I beg to differ.
I mean, right now, I could use any number
of services to hire random persons around
the globe to install posters for me.
Although, given that no poster was located
more than an hour away from an airport leads
me to believe that one or multiple persons
actually traveled to these locations.
I mean, some of the posters were found within
walking distance of an international airport.
The fact is that anyone with a disposable
income and enough time on their hands would
be able to create the illusion of a vast secret
network spanning the globe.
Not saying that is the case with Cicada 3301 but it is
nonetheless a possibility that cannot be discounted.
With all of that being said, I personally
think a loose-knit group of privacy-minded
hobby-cryptographers to be the most plausible
Cicada made their last public statement in
April of 2017, merely warning against disinformation,
but the current status of the third puzzle
and the possibility of a fourth
remains clouded in mystery.

  1. This is cool and all but can we get real here for a second, what do you think happened to the people that made it to the end?

  2. I kinda get it because yknow they come out after forever and are hidden in plain sight, then disappear like they were never there

  3. YouTube from 2011-2019 watch a vid of this subject….

    Me from 2011-2019 -_-…….

    Me at this moment in time okay I’ll watch the damn bug video!!!!

  4. "You've made it. Now download 2 apps from the play store and run them for 30 seconds to complete the human verification"

  5. Am i the only one who thinks its crazy to travel from country to country to look for a piece of paper taped up at some random place?

  6. My guess it's a group of nerds wanting to have some fun and add a few more nerds to their online friends circle.
    Maybe they did want to develop something for internet privacy as he stated.
    But international conspiracy, oh please

  7. They chose their “talent” and those they told “be patient” are probably those who they’d choose when and if they needed more on their team. They made it seem as if everything came to a halt to throw everyone off. Maybe this had to do something with the whole Q movement.

  8. If you didn't notice the date 01/04/12 but it was 04/01/12
    So it could be April fool's day in 2012
    So the intelligent society wanted to make the world's most intelligent 's fool

  9. No one has to believe me but I got a family member of mine to look into this and she is extremely good at cryptography and coding in general. She has solved a lot of the work that hasn't been solved up till now. More information on the way.

  10. With every poster being in a major city, it is extremely likely that it would be very close to an international airport.

  11. Whoever Cicada is, I'll be damned if they aren't a good musician. Minimalist acoustic guitar with a mysterious, lo-fi pastoral feel to it, I love it.

  12. If you shall, let me exiewhflugdsuifgjehshdjblghelhsavdlcvlyavslvdlvawgk76r287t3297t8r9t2t9r t72tr727t8rtor2882yH

  13. It seems like winners of the previous trials were left to the wayside because Cicada (and anyone following) could easily see that collusion polluted the previous winner pools, so they made the third test harder, the true test.

  14. It's obviously all about cryptocurrencies and their technologies behind each coin/token. 99% shall not believe in it so then they will be left behind. fiat is the biggest ongoing scam to date.

  15. Hey there, internet friends. I'm creating a club at my school which is dedicated to decipher Liber Primus. Check back on this comment later to see my success, I shall be posting the translations in a subreddit which I shall link in this comment once I'm done.

    (success not guaranteed)

  16. The winner gets to meet the real Illuminati, as they need someone with an exceptional IQ to create a cryptocurrency for them and be one step ahead of Mark Z., before he (Mark Z.) creates his own world cryptocurrency and take over.

  17. SO, the first puzzle was used to find people with talents in certain areas, who, hopefully, share the ideas of 3301. All lost interest quickly, so a second puzzle was launched with the same intent, basically a fresh start. Possibly while the second puzzle was still in action, the third was already in development – Do they need more people? Was it ever the intent to have only one puzzle? And if multiple were planned: Why at this point in time? What happened? What changed? -, but something unforseen happened to 3301. The puzzle automatically launched, albeit incomplete.

    – Taking into account that 3301 claims to not be involved into illegal activity gets rather difficult if the group – as I also belief that theory to be the most plausible – actually operates internationally. Rights and laws differ from country to country.
    – The fact that they ask not to share received information – an action not in line with their (claimed) beliefs – hints at dangers which 3301 beliefs to be valid reasons for concern. Whether these dangers are, indeed, valid reason for concern, possibly a result from the first point, remains to be seen. As does their existence.

    The phenomenon largely dubbed "Cicada 3301" asked more questions than it answered. It adresses, however, a problem that will likely only grow: The once again starting belief that surveillance is good. That privacy has to be sacrificed for security. That such measures are necessary. The consequences of 3301's actions also remain to be seen. And whether or not it was their intention: The phenomenon of "Cicada 3301" sheds light upon the question "What value does your privacy have to you?". And that, my friends, is a question we should all ask ourselves.
