Cicada 3301

For those of you still unfamiliar with the Cicada 3301 puzzle, it has been called “the most elaborate and mysterious puzzle of the internet age” by Metro, and is listed as one of the “Top 5 eeriest, unsolved mysteries of the Internet” by The Washington Post. Here are links to some of the articles that were written about me and my work on the original Cicada 3301 challenge back in 2012:

The Internet Mystery That Has the World Baffled

Update (2014-01-05):

The integer sequence found in the first QR code felt familiar, but I was not sure why. I must admit that I did not give it much thought either, after ruling out any hidden ASCII message. Today I received a message from someone calling himself RoboSimian, with the following suggestion:


Not sure if it means anything, but at first glance the integer
sequence contains sub-sequences similar in nature to the Fibonacci

0, 1, 1, 3, 5, 8, 1 3
13, 45, 58
but I’m not sure what to make of the rest:

Note that the fibonacci sequence begins with 0, 1, 1, 2, 3, 5, 8 though, so the 2 is missing. Looking at the rest of the sequence, it turns out that it is in fact a perfect match with the fibonacci sequence, with all the 2:s removed! :)

So, the question is whether the sequence itself, the missing 2:s, or the continuation of the sequence, is the important part here. Note that there was a NUL-byte at the end of the decoded message, after the sequence. This could have some significance as well, suggesting that the sequence has been truncated, for instance.

Update (2014-01-05):

Two days ago I received the following message, from someone claiming to represent Cicada 3301:

When is a BWV not a BWV?
You have gone farther than anyone.
You have also been intelligent enough to identify false 3301s.
Now I shall give you some answers. Our group is dedicated to
re-cloaking privacy. You missed some hints. The Bach Mp3 was something
that most hunters missed. 1033 BWV is not a Bach piece. It was
composed by a man named Christoph. CPE misidentified the piece as his
fathers..Pity. CPE was a teen, so forgive him. Seeing that so many
false 3301’s now join the game, we will post our next series of clues
on a spoof website. We will be watching your work, since it is
superior to anyone’s work out there. Please treat this message with
the same level of skeptical vision as any other errant email that you
receive. Our goal, Clevcode, is to re-cloak humanity.
Good luck,


Someone also just posted this as a comment to this page:

Secondly, has anyone bothered to vet, and I mean, really vet the Bach clue?
I have.
It’s a ruse, and leads directly to 1033 BWV
Further study leads me to believe Bach never wrote that piece.
3301 is leading us to a place where we doubt authenticity itself. We question experts. We patiently wait for a periodical cicada.

When digging into this a bit, many sources of information are found.
This is an excerpt from one of them:

The Sonata in C major for flute and continuo, BWV1033, is preserved in a manuscript in the hand of C P E Bach, dating from the early 1730s, and in which he attributes the piece to his father. Its origins are obscure and disparate, perhaps since its first two movements, at least, are arguably more convincing as pieces for an unaccompanied melody instrument. Yet, in spite of sequential and cadential crudities, the music is not without either merit or charm and is, by and large, satisfying to play. There is a shapely nobility to the opening ‘Andante’, and a far from displeasing virtuosity, however simply conceived, in the ensuing ‘Allegro’. The music of greatest substance, though, is to be found in the ‘Adagio’ which, like the concluding Minuets, ‘alternativement’, is not devoid of Bachian character. Bach’s hand can surely be sensed, too, in the fully written-out parts of the first Minuet which bears relationship to a movement of a concerto by Bach’s Merseburg contemporary, Christoph Förster; but, be that as it may, the sonata is uneven in quality and inconsistent in technique. It has been suggested that the harpsichord accompaniment was added later, perhaps by one of Bach’s pupils.

The new message from Cicada 3301, or someone claiming to represent them, is probably suggesting that BWV1033 was composed by Christoph Förster rather than Johann Sebastian Bach.

Regarding posting their next series of clues on a “spoof web site”, this is probably it:
Cicada 3301 releases clues to BBC News

When I first visited the link in question, I actually thought it was a real article. ;) Note that the real BBC site uses and not though.

Regardless of whether it is the real Cicada 3301 that has been sending these messages and releasing clues or not, considering that it is now January 5, I think it is quite likely that we will see a new Cicada puzzle being released very soon.. :)

Regarding the fake BBC site, I analyzed the “Within every image there is always a story” image, and found two QR codes.

The first one decoded to this string:

Decoded as a hex string, it yields the following message:
Sometimes the stories are hidden well, with many keys and many locks

The second one decoded to this string:

By looking at the patterns in this string, it is quite obvious that it consists of groups of three digits, which turns out to be octal-encoded. When decoding this string, we get:

Sometimes the stories are even hidden to the maximum degree

For those of you who are curious how I performed the decoding, revealing the QR images was done using GIMP, by adjusting the color curves. That gave me the following image:

I manually stitched together the QR code in the corners to qr1.png, and inverted the colors, and decoded it using:

I placed the QR code from the top and bottom half of the picture in qr2.png, inverted the colors and decoded it using:

Since there is still no PGP signed message, it is doubtful that this is the real Cicada, but time will tell…

PS. The next logical step, if someone wants to analyze this further, is probably to use the OpenPuff steganography software, and maybe the “01135813134558914433377610987159758441816765” string as a key (hex-encoded binary data?), in order to extract yet another hidden message from the image on the fake BBC site, or from something else… Note that OpenPuff can use multiple keys, and multiple carriers (files) with hidden data.

I also received this message yesterday:

Subject: Is this a message from Cicada?

Hi there,

I am a freelance content creator and recently came across some
information regarding Cicada 3301, specifically the puzzle due to be
released tomorrow, I have written an article on it and saw that you
have already had some content on your site regarding it, I was wonder
if you would be interested in putting it up on your site. I’m not
asking for a fee in return but I would be grateful for a link through
to my fiverr page.

Please let me know if you might be interested.

Thank you,

Maria Jacobsen Holmes

With the follow-up message below:

It wasn’t actually a message that I received it was a request to write an article – I do freelance content creation, with specific words and information in it. It was also requested that I requested that I send it to you with the subject line I used. Would you like copy of the article?


When I replied that I would like to see the message, I got this reply:

It’s just a general information post but I’ve put in bold the key words I was asked to put in before sending the article to you :).

Oh and happy New Year!

The actual message (including the keywords put in bold) was:

3301 is a mysterious organization that has captured the attention of web aficionados since
January 5th 2012 when a cryptic and baffling clue was released. Since then, on the same
date each year, another clue has been released. What appears to be a simple image with
some seemingly random phrases actually gives way to being one of the most
sophisticated and well thought through web puzzles in the history of the internet and has
attracted the attention of some of the most talented netizens of the world – fuelling
rumours that it is a recruitment campaign for anything from governmental intelligence
agencies to anarchistic hacker organizations. However the reality behind the puzzle is no
where near close to being revealed and remains shrouded in mystery and left to the
speculation of online chat rooms.

The clues themselves demand a very interesting skill set; they don’t just contain
cryptograms and riddles but advance far out of the traditional domain of online puzzles to
include historical themes, music, literature, poetry and much, much more. Although some
major organizations, including intelligence ones, have used methods that bear some
resemblance to 3301, nothing has ever come close to the scale and complexity of Cicada
3301; and the fact that so little is still known about the mysterious organization today just
adds fuel to the fire that has captured global attention.

The purpose behind these puzzles aside, online forums and chat rooms have exploded
with users keen to share information and efforts in order to uncover the enigma behind this
increasingly mysterious organization. Although to a large extent these conversations
contain so many rumors, theories and speculations that they end up increasingly
complicating matters, the usefulness of this information should not be ignored. There are a
few recurring themes amongst this information, these combined with the new clues seem
to be hinting that the focus for those wishing to solve the puzzle should expand to include
a historical element. One mysterious figure has been brought to light and one wonders
what the connection might be between St. Germaine, an 18th century ‘wonder man’
rumored to have been an incredibly powerful alchemist, a musical genius, friend of high
ranking noblemen and kings, and perhaps most importantly immortal – and Cicada 3301.
The recent clues have also been shifting the focus more towards music as a way to solve
this riddle; the buzz on the chat room seems to indicate that musical leads hint towards a
Pythagoras connection. Could this mean that 3301 are changing their delivery method
and moving from TOR to actually embedding their message into music? Maybe the
next set of clues released on January 5th will provide a little more clarity, but this in itself
adds yet another element to the mysterious 3301 organization – Why this date and does
the relevance of this date have something to do with solving the problem?

Note that the comment I received about the Bach clue was from someone calling himself “Germain”…

Update (2013-11-29):

I think this is probably an imposter, rather than the real Cicada, but I got a cryptic message after the article in Daily Telegraph, from someone calling himself Tibiceninae (the name of a cicada subfamily)… Unfortunately I don’t have the time to look into it much deeper myself at the moment, but I have collected my notes on it so far here:

On January 4th 2012, an image was uploaded to various image boards, possibly originating at the infamous /b/ board at 4chan. When I came across it, I didn’t think much of it at first, but still decided to look into it just in case it turned out to be interesting. I have always had a hard time resisting a challenge. This is the image that was posted:

My first thought was that it used steganography to hide a message, and since it was a JPEG image I tried using stegdetect by Niels Provos in case one of the detectable schemes was used. Since stegdetect have not been updated in almost 7 years, I didn’t really get my hopes up that high though, but it is always worth a try. ;) The result can be seen below:

It did not detect any of the common steganographic schemes, but notified me of 61 appended bytes of ASCII text. Since my next move would have been to use “strings”, I would have discovered this anyway, but stegdetect was kind enough to tell me directly instead. :) So, let’s see what we have:

This is quite obviously a shift cipher of some sort (also known as a Caesar cipher), with “lxxt>33” being the ciphered version of “http://”. A shift cipher replaces each letter in the plaintext with a letter (or in this case, arbitrary ASCII character) with a letter a certain number of positions down the alphabet. So, let’s compare the ASCII values for the cipher text with the ASCII value of the supposed plaintext to see what the shift value is:

In this particular case, this might have been a bit overkill, since we could just as well have manually counted the distance between h and l in the alphabet. ;) It is probably not a coincidence that Claudius happens to be the 4th Emperor of the Roman Empire, and the shift value happens to be 4, either. To decipher this, a perl oneliner is enough:

The image at the URL above can be seen below:

It seems like the challenge is a bit harder than a caesar cipher after all. Note that the message contains the words “out” and “guess” though, which could be a hint that we are actually supposed to use the old OutGuess tool to extract the hidden message. Incidentally, OutGuess is also developed by Niels Provos and is available for download from the same site as stegdetect ( Unfortunately, it seems like stegdetect is only able to detect when the older OutGuess 0.13b has been used and not OutGuess 0.2 (from 2001!). :D

Using outguess 0.2 with the -r option immediately reveals the hidden message in the original image:

The hidden message can be found here.

Now things are actually getting interesting. Although the challenge have not been required any particularly advanced skills yet, someone has obviously been putting some work into it. The hidden message says that we should go to the following URL:

The hidden message also includes a so called book code, consisting of a number of lines with two digits separated by a colon on each. The book and more information should be found at the URL above. Book ciphers are ciphers that use a book or a text of some sort as the key to encode a secret message. Traditionally, they worked by replacing words in the plaintext with the locations of words from a book, but in this case it seems more likely that the two digits separated by a colon in the code refers to a line and column number.

When visiting the Reddit page, we can make a number of observations. Most notably, there are a number of posts by the pseudonym CageThrottleUs that seem to consist of encoded text, which we can assume to be the book. It looks like an ordinary Caesar cipher may have been used, but on a closer look no shift value results in readable text. It seems most likely that a key of some sort is required to decode the text.

Looking closer on the page, we can see that the title is “a2e7j6ic78h0j7eiejd0120”. The URL itself is a truncated version of this. To the right, below the “subscribe” button, the title text is repeated and “Verify: 7A35090F” is written underneath. We can also see pictures of some mayan numbers on the top of the page. Mayan numbers are quite logical, at least from 0-19. A dot equals one, and a vertical line equals five. Two lines thus equals ten, one line with two dots equals seven (5 + 2) and so on. There is also a symbol resembling a rugby ball that equals zero. :)

The number sequence that is written using mayan numbers is as follows:
10 2 14 7 19 6 18 12 7 8 17 0 19

Comparing this with the a2e7j6ic78h0j7eiejd0120 in the title, we can see that numbers below 10 in the sequence above is also found in this string, at the same positions. Also note that instead of 10 we have “a”, instead of 14 we have “e”, and so on up to “j” being 19. Since the title of the page contains 23 characters and there were only 13 mayan numbers is is quite likely that we are supposed to continue converting characters from the title to numbers. This gives us:

10 2 14 7 19 6 18 12 7 8 17 0 19 7 14 18 14 19 13 0 1 2 0

This could very well be the key required to decode the text. Regarding the “Verify: 7A35090F”, it may refer to any number of things. A PGP key ID is, however, a good assumption since it consists of a 32 bit value normally encoded as eight hex characters and since PGP keys can be used to verify the signature, and thus the authenticity, of messages signed with a PGP key. This could be quite handy, in case the challenge goes on and in case people decide to drop false leads to the people working on it. So, let’s try to import the public key with the ID in question from one of the common PGP key servers:

The comment for the key mentions 3301, which was used as the signature in the original image. It also includes the word “cicada” and the number 845145127, which may turn out to be significant at a later stage. Note, for instance, that cicadas emerge from their hideouts under earth every 13 or 17 years depending on which kind. By emerging every N:th year, where N happens to be a prime number, cicadas actually minimize the possibility of synchronizing with the life cycles of birds and other animals that prey on them. Also note that 3301 is a prime, and that 845145127 has 3301, 509 and 503 as its prime factors.

When taking a closer look at the lines of encoded text posted to the reddit page, we also find two images. One named Welcome and the other one Problems?. By using OutGuess again, we find another couple of hidden messages:

The messages verifies both our assumptions, since they are indeed signed using the key ID 7A35090F and since the second one specifically says that the key “has always been right in front of your eyes”. In other words, it is likely to consist of the numbers we discovered being encoded as characters in the title of the page. The first message also specifically states that all messages from now on will be signed using the PGP key with ID 7A35090F.

All that remains now is to figure out which encoding scheme has been used so that we can apply the key to the text. Since a shift cipher was used in the original image (although it was used as a decoy), perhaps the numbers are different shift values. In other words, for each line of text, shift/rotate the first letter ten steps in the alphabet, rotate the second letter two steps, the third letter 14 steps, and so on, to get the plaintext. Implementing this in C results in the following:

The file “reddit.txt” consists of the lines posted to the reddit page so far, in the order that they have been posted. Note that this is not in the exact order that they are shown on the reddit page. As you can see, our assumption was correct and we can now decipher every line of text that has been posted, and try to apply the book code that we got in the message hidden in the original image.

Using a small bash script, we can apply the book code to the text from reddit to retreive yet another hidden message:

Although we can easily see which phone number is being refered to, it’s obvious that the output is a bit garbled. For the sake of completeness, let’s look into what the cause might be. The first letter that is garbled is the “n” in number that has been turned into an “o”, then the “r” in three which have been turned into an “s” and so on. The upper case “B” may have been intended though, although it seems a bit off. There is actually a lower case “b” on the same line that is used for encoding the upper case “B”, but the upper case one comes first.

When looking at the line corresponding to the “n” turning into an “o” (line 26, column 65), we can see that there is actually an “n” right before the “o” at column 65 (from the name “Kynon”). Looking further down, at the line corresponding to the “r” turning into an “s” (line 48, column 43), we can see that the expected “r” is right before “s” on this line as well (from the word “daggers”).

Another thing in common for these particular lines of text is that they include a period somewhere before the character that has been decoded incorrectly. If we assume that periods, which end sentences, should count as two characters instead of one when applying the book code we get this, which looks a bit neater:

So, to continue the challenge we need to call the (214) 390-9608, a Texas based phone number. Whoever is behind this challenge, they have obviously put some effort into it. :)

When calling the number, one is (or rather, was, the number has now been deactivated) greeted by the following message:
“Very good. You have done well. There are three prime numbers associated with the original final.jpg image. 3301 is one of them. You will have to find the other two. Multiply all three of these numbers together and add a .com to find the next step. Good luck. Goodbye.”

When examining the PGP key, we already noted that it included the number 845145127 in the description, and that this is the product of 3301, 503 and 509. When looking at the metadata for the original image, we also note this:

Seems like we’ve solved this stage as well, now let’s head to to find the next part of the challenge. :) When I first arrived at the site, it just displayed an image of a cicada and a countdown. Using OutGuess again, the following signed message could be extracted from the cicada image:

Just like before, the message is signed using the Cicada 3301 key. The challenge so far have been a quite fun, and rather different, experience and I’m looking forward to see what comes next.

When the countdown was finished, at 17:00 UTC January 9 2012, it was replaced by strings of digits resembling GPS coordinates. Also, the image of the cicada now contained another signed text containing the same GPS coordinates as on the web page, except for two that were only on the webpage (37.577070, 126.813122 and 36.0665472222222, -94.1726416666667):

Using Google Maps ( I could search for each of these locations, and in most cases even get a street view. The locations were spread out around the world without any obvious connection (USA, Poland, France, South Korea and Australia), except for perhaps each of them being home to some talented hackers. At this point I thought it would be the end of the game for me, since I am far away from all of these locations.

I was still very curious on how the challenge would continue though, and found that there are groups of people working on this from all over the world. One of these groups had set up an IRC channel at, and managed to get people to check out the locations at the specified GPS coordinates. What they found was notes attached to lightpoles, with the cicada image and a QR code. When scanning the QR code, they got image URLs with a black and white image of a cicada and the text “everywhere” and “3301”. Each image also contained a hidden signed message. Even though there were 14 locations, only two different messages were used though.

One of them had with the following text at the top of the message (full message here):

The other one had this text (full message here here):

They both also included a 22 line book code. Both of them included the text “the product of the first two primes” at line 3 and 15, and one of them also included the text “the first prime” at line 8. This probably means that the characters on these positions should be replaced with the numbers described. Note that the definition of a prime number is a natural number greater than 1, with no positive divisors other than 1 and itself. This means that the first two prime numbers are two and three.

The three lines of text in each message seemed likely to be a hint to which book/text to use as the key for the included book code. By googling for some keywords in the second message (poem fading death read only once vanish), the Wikipedia entry for a 300-line poem by William Gibson is among the first hits. The poem is called Agrippa (a book of the dead) and according to Wikipedia “Its principal notoriety arose from the fact that the poem, stored on a 3.5″ floppy disk, was programmed to erase itself after a single use; similarly, the pages of the artist’s book were treated with photosensitive chemicals, effecting the gradual fading of the words and images from the book’s first exposure to light.”. This fits the description perfectly.

When googling for william gibson agrippa, the first hit is Taking this text, including line breaks, as the key for the book code results in the following:

Judging by the “.onion” at the end of the string, this is actually an anonymous hidden service in the Tor network. Unfortunately, by the time I arrived at this stage the Tor service was not available anymore. 3301 had concluded the last couple of messages with “You’ve shared too much to this point. We want the best, not the followers. Thus, the first few there will receive the prize.”, so it was probably first come first served. The ones who were lucky enough to arrive in time (most of which did not solve much or any of this challenge themselves, since people were sharing their solutions) got to enter their e-mail addresses and were informed that they would be contacted in few days.

By this time, someone noticed that the DNS entry for had been removed. By using the IP ( it was found that the page that recently had GPS coordinates had changed yet again, to a seemingly empty page. On a closer look it turned out to consist entirely of spaces, tabs and linebreaks. Since every line contained a multiple of eight spaces/tabs, it seemed likely to be a plain binary code. This was confirmed by:

The message simply contains ten different 12 digit numbers. As it turns out, each of these correspond to image URLs such as:

Each of these images contains a hidden message that can be extracted with outguess, and it turns out that it’s the same messages that could be extracted from the images found through QR codes on notes at the GPS-coordinates mentioned earlier. Turns out we didn’t have to be at one of those locations after all. :)

Regarding the remaining code, it is very likely to refer to the same .onion site as before. Just to be sure, and not to leave out any piece of the puzzle, it would be nice to solve that one too though.

My thoughts so far are these:

“In twenty-nine volumes, knowledge was once contained” may refer to the 11th edition of Encyclopedia Britannica, which consisted of exactly 29 volumes and that is now in the public domain and available for download since it was released back in 1910-1911.

Regarding “How many lines of the code remained when the Mabinogion paused?”, note that the text posted to the reddit page is from “The Lady of the Fountain”, which is the first out of eleven stories from medieval Welsh manuscripts in the collection called the Mabinogion. Also note that there was a pause for about 24 hours after the 65:th encoded line of text was posted to the reddit page. After that, new encoded lines have been posted about every 6th or 7th hour.

Assuming the code will continue until “The Lady of the Fountain” is finished, we will need to figure out the total number of lines in that story. To do that, we need to find the text that 3301 uses as their source, so that line breaks are placed on the same positions. After a bit of searching around it turns out that the source that 3301 uses is from Project Gutenberg (here). Blank lines are discarded, and lines with only one word on them are being appended to the preceding line. Applying those rules to the entire text of “The Lady of the Fountain” results in a total of 833 lines. Thus, the number of lines of code that remained when the Mabinogion paused is 833 – 65 = 768 (which also happens to be 512+256, but I guess that may be a mere coincidence after all).

Finally we have “Go that far in from the beginning and find my first name”, which could mean a number of things. My guess is that we should go 768 words, sentences, word definitions, characters or pages into the 11th edition of Encyclopedia Britannica. Question is where we are supposed to go from there, since it ends with “and find my first name”. By this, I assume we should only find a certain name at this particular position, and then from this name find the actual text to use as the key for the book code.

I also noticed that the code for this part only use 27 lines, with columns ranging from 1-66 and many columns being above 30-40. This rules out most poems, that usually don’t have long lines. It could very well be a text straight from the Encyclopedia Britannica, however. Due to the large number of possibilities I have not looked into it much further than this, and so far I don’t think anyone have come up with the solution for this particular puzzle. So, anyone up for it? :)

    • Kisme Rae

      i have just found out about cicada 3301 and am extremely interested. i was wondering if you could help me to start the game. i do not have any of the code breaking programs needed to decipher the clues and am also unsure where to even begin. when i heard about cicada i instantly became fascinated and would love to become involved in it. you seem to know so much more than any of the other site i have looked at and seem very knowledgeable in the subject. i can only hope that you will contact me soon and help to get me started. i understand if you do not have the time to help me, after all i am just a no-name to you.

    Im working on it….

  • boss

    I love your work.

  • vander

    I have no clue about anything, but I just came up here and I want to congratulate you on your shocking skills and intelligence. Great work, sir.

    (do not suspect, this comment is not a hint xD )

  • marty

    if there is anything i can do to help please let me know, it would be a shame not to see this through seeing how much effort you have put i

  • Janus

    It´s sad that this requires Internet/Coding skills, the search for highly intelligent people should not be limited for those which have this skills, but for everyone.
    But maybe they search that kind of people, who ever “they” are.
    My guess is that they are from 4Chan,Reddit or something similar.
    Irc Channels, Coding and things set up at different places on the earth which is kind of easy if you ask the right people on the internet:
    Anyway it kind of motivates me, i will try to solve it even without greater knowlege this matter.

    • Janus, every thing here can be done by hand (aside from the PGP verification and outguess). Je’s use of UNIX utilities to solve this is a convenience, not a necessity. The same can be done with almost any file; manipulating text in a shell is one of the most fun and easy ways to do so.

      Now I will concede that later in the puzzle, things do get more technical. To the point at which this narrative terminates, however, there is little need of the skills you mention.

    • Psaltoda Moerens

      These skills are not necessary, so do not be discouraged. However, OP lies. He has not come this far in the puzzle, and is misleading you. This is neither hint nor help to you. Only a simple warning that this man misleads you in the puzzle that has already concluded. Use it as practice, if you must, but if you truly would like results, win the current game. I will see you on the other side.

  • Procyon

    “Thus, the number of lines of code that remained when the Mabinogion paused is 833 – 65 = 768”

    Don’t know if it’s important, but the first edition of Encyclopedia Britannica was published in 1768. So maybe we shouldn’t be looking at 11th edition, but first. The question – where to find it? :D
    I just found out about this today, so I still haven’t worked anything up.

  • Procyon

    In the preface of the first edition, in the place of 768th word is a sign for repetition, since the essay was written by the same author as the previous one. The name of the author is Charles Alston. Don’t know if I’m helping or spamming, tho.

  • kala

    Will you update this post if you find out more about this? Who do you think are “they”?

  • Maria

    Do you know anything about what happened from the point the e-mails have been sent on? The few people who got to the Tor site on time and submitted their addresses got an RSA encrypted message to decrypt. After that, I read there was a midi file with a hidden message to report back.

    You havnt heard anything more because the people who reported receiving those emails have dropped out of view/do not want to participate.

    It’s pretty suspicious of you ask me, there was one guy who was posting non stop about his progress, received the said email, and was never heard from again.

    It’s been speculated that it’s a hiring process for a highly funded hacker program that plans to permanent destroy Facebook…..they must have been paid a lot If they kept their mouths shut

    To those who have followed this game as I have from the beginning, I just wanted to take a moment and let you know that the “game” is over. Those who have made it in the end have received their final emails, which are confidential (however, if you search pastebin, you might just find some people who like to break the rules).

    As one of the players in this game, this has been an exciting experience. Now on to other things…

    Is there anyone who can post a link to proof or speculation of where this originated?

    • Betyouwishyouknew

      The original final.jpg image was posted to several image hosting sites on January 5th. It was _not_ posted on 4chan. Source: 3301. Proof: SO. No, this was not in a PGP-signed message and no, you’re not going to find it anywhere public.

      As for the resolution, I can confirm that it was recruiting and the results were worth it. We’re now working behind the scenes to save the Internet. Wish us luck!

      While I’m here, I’d be happy to answer any other questions people have.

      No, I’m not supposed to be telling you these things.

        Since you claim you’ll answer questions, could you provide an example of how this “organization” is currently working to save the internet?

        I await your reply.

  • Miles

    I don’t want to sound too paranoid but maybe it was an elaborate attempt setup by one or more agency to flush out hackers or potential trouble makers.

    It was mentioned in the article that the GPS coordinates were in a number of specific countries that all have hackers living in them, it might explain why the email recipients became silent.

    Whatever it is the original creators of 3301 knew how this would end and tried to cover it up. This stinks to high heaven I hope people haven’t given up.

    “When taking a closer look at the lines of encoded text posted to the reddit page, we also find two images. One named Welcome and the other one Problems?. By using OutGuess again, we find another couple of hidden messages”

    searching at google for “charles alston cicada” i found this

    Seventeen-year cicada
    In 2004, during a year in which Brood X of the seventeen-year periodical cicada (Magicicada septendecim) emerged from the ground in large numbers, columnist Courtland Milloy wrote in The Washington Post an article entitled “Time to Create Some Buzz for Banneker”.[40] Milloy claimed that Banneker “is believed to have been the first person to document this noisy recurrence” of the insect. Milloy noted that Banneker had recorded in a journal published around 1800 that the “locusts” had appeared in 1749, 1766 and 1783. Milloy further noted that Banneker had predicted that the insects would return in 1800.

    Gabriel: To continue, one would have had to be one of the first visitors to the Tor hidden service so one could enter an e-mail address to receive further pieces of the puzzle. Unfortunately, my sleep-wake cycle resulted in me missing that window of opportunity. :)

    Regarding the remaining book code, i.e, one of the two possible hidden messages that could be retrieved by visiting one of the 14 locations pointed out by the GPS coordinates, I am quite certain that it decodes to the same .onion address as the other book code.

    The reasoning behind this is that it would be incongruent with the rest of this puzzle, which have had multiple clues leading in the same direction in each step, if one would have to retrieve messages from several locations to go to the next step.

    Looking at the book codes, one can also see that they are of the same length, and that they have the same digits at the same locations in the string (..6….2……6…….).

    Since there was no chance of continuing the puzzle, I have not looked at it since.

    However, it has recently come to my attention that there was actually a new image posted one year after the first one, with a continuation of the puzzle. Assuming Cicada 3301 are still “recruiting” I think the chances are good that they will post yet another image on 4th of January 2014. :)

    • Germain

      That would be January 5th.
      Secondly, has anyone bothered to vet, and I mean, really vet the Bach clue?
      I have.
      It’s a ruse, and leads directly to 1033 BWV
      Further study leads me to believe Bach never wrote that piece.
      3301 is leading us to a place where we doubt authenticity itself. We question experts. We patiently wait for a periodical cicada.

    Did it ever occur to anyone else that the ‘recruiting’ is in symbiosis and or somewhat following the actual brooding period of cicadas?
    Whereas there will be no further ‘ARG’/’recruiting’ until 2016(Brood V).

    • I am GhostedPast

      That is interesting… Also a cicada’s life cycle revolves around Fibonacci numbers. I read somewhere that 3301 is a prime number and it has something to with the Fibonacci sequence, I couldn’t figure it out however I think that the Fibonacci sequence has an important role in this puzzle.

  • Pingback: Cicada 3301. Mythos, Kampagne, oder Rätsel? | The LastBlog()

  • Divide 3301 by 8 and you get 412.625. Factor 412625 and you get 5,5,5,3301. Dial 18005553301 and you get a carrier.

    • Joel Eriksson

      1-800-555 3301 is a fax number belonging to a Sam Chambers, according to :)

      Regarding 3301/8 = 412.625 and 5*5*5*3301=412625, it is due to 5*5*5*8=1000. :) This equation holds true for any N: N/8=(5*5*5*N)/1000

      I’ll have to admit that I thought it looked like a neat mathematical coincidence for a while though! :D

  • Twixtfanatic

    This is most likely a dead end, but 3301 is the third term of a couple of interesting integer sequences. From the OEIS website:

    A054800 First term of balanced prime quartets: p(m+1)-p(m) = p(m+2)-p(m+1) = p(m+3)-p(m+2).
    In other words, 3301 is a prime number, and the next three prime numbers are of the form 3301+K, 3301+2K, and 3301+3K. In this case, K=6, so the next three primes are 3307, 3313, and 3319.

    A033451 Initial prime in set of 4 consecutive primes with common difference 6.
    This is a subset of the previous sequence, where K is always 6. It is somewhat surprising that these two lists are identical up to the first 24 elements. For A033451, the 25th term is 75521, but for A054800, the 25th term is 74453, and the value of K for that term is 18.

    The first two terms of both sequences are 251 and 1741. The above link lists 255 sequences which 3301 is part of, but it shows up much later on the list in those other cases.

    I don’t know who may be behind this Cicada 3301, but just by curiosity I googled what had happened on the year 1033, and apparently there was paranoia in Europe that the world may end because of the millennial anniversary of Christ’s crucifixion, not sure what to think of that…

    Unfortunately you missed part 2 of the challenge as the page was changed. You were instructed to enter an email address and you would have been emailed instructions (there was also a second chance round with another link using instead of The instructions involved a low bit modulus RSA key, finding the key pairs, going back to the last onion page and entering your pair, as each person was given a different key. This would get you a couple of .midi files and a substitution cipher would get you instructions to set up a gpg key, and email to the address that emailed you with the RSA info in the beginning with the final words deciphered from the .midi files. Just to give you the answer you may be looking for, what skills do you think this journey specifically targets? If you look at the 2013/2014 that are supersets of 2012. People that were chosen from 2012 are tasked with working on 2013 and so on. Take care.

    I know this isn’t a very intellectual observation, but the Cicada dude mentioned or implied something from the bible during your search 3 times.
    “It’s not a search for the holy grail”

    and in that code stuff (Which I know nothing about, I’m a 13 year old girl)
