@ngn is this confirmed cicada?
 
ngn
@Quintec not yet
 
Where did this come from?
 
ngn
at some point there should be something signed with a key they published years ago
 
What is this source of all this though
 
ngn
3:51 AM
@Quintec MilkyWay90 got a strange comment on his website
 
Interesting... I can't imagine why they would target that specific place, sounds fun though
 
ngn
Cicada 3301 is a nickname given to an organization that on three occasions has posted a set of puzzles to recruit codebreakers/linguists from the public. The first internet puzzle started on January 4, 2012, and ran for approximately one month. A second round began one year later on January 4, 2013, and a third round following the confirmation of a fresh clue posted on Twitter on January 4, 2014. The stated intent was to recruit "intelligent individuals" by presenting a series of puzzles which were to be solved. No new puzzles were published on January 4, 2015. However, a new clue was posted on...
@Quintec ^ more about it
(or at least what we suspect it to be)
 
ngn
4:22 AM
@MilkyWay90 how did you know what the rickroll's plaintext should be? :)
 
@ngn I looked at the description
and "octal-ed" it
It was encoded in octal
so a print("".join(chr(int(i,8))for i in input().split())) did it
I put the description as input to that
 
ngn
but that gives the ciphertext, doesn't it?
 
@ngn Yeah
That's what I was working on
little did I know that atbash decoding would have solved it :(
and little did I know what atbash was
 
ngn
so you just guessed that that is a cipher for shelley's other poem :)
 
Yeah, it really looked like it
same length, and the other poem was already there
 
ngn
4:27 AM
makes sense, given the spaces and punctuation are at the right places
 
yeah
0:17 - 3^7
0:29 - 2^5
0:45 - 9^4
0:06 - 3^4
0:35 - 5^4
0:18 - 4^9
0:58 - 3^7
For that, maybe try bitwise xoring the numbers
like 3 and 7, 2 and 5, etcetera
Theres also a new clue
Try atbash decoding it
Argh firbase isnt working
 
ngn
@MilkyWay90 where did you get a clue from?
 
@ngn www.randomstuffonline.com/chat.html
Where the clues started manifestign
*manifesting
Okay logged in here
I was user10909325, since I forgot to login
Name: zouivwl
Contents: Lmv urmzo xliivxgrlm, rm gsv Xzvhzi, xszizxgvi 14, 18, 19, zmw 21 ziv xzkrgzoravw.
@ngn see above
^^
 
ngn
@MilkyWay90 "One final correction, in the Caesar, character 14, 18, 19, and 21 are capitalized."
 
@ngn Oh, I just copypasted
@ngn Wait nevermind, I didn't see you had the quotes there
I thought you were talking to me for a sec
 
ngn
4:38 AM
i decoded with atbash
 
Seems like it was encoded with atbash, yeah
atbatsh3.png
Oof
Never saw it was named that
01/12/2019 17:20 141 151 146 162 145 144 157: 561 1105 1729 2465
 
ngn
so they keep giving you clues on your website? they must be watching us :)
 
probs
Actually probably not
What does the contents say for the message I just sent
1 min ago, by MilkyWay90
01/12/2019 17:20 141 151 146 162 145 144 157: 561 1105 1729 2465
I decoded the name as 'aifredo', but not the contents
B♭ A# A A G D♭ B♭ B♭ D D D
for this, we should maybe put it in an mp3 or midi file
@ngn That's what I got
 
ngn
i'm stupid. ofc it's not octal
 
or something similar
 
ngn
4:45 AM
there's a 9 there
 
and I tried all bases
all the way from base 10 to base 36
0:17 - 3^7 - person twirling
0:29 - 2^5 - person nodding head
I have a feeling there are very faint lyrics
Restricted Mode has hidden discussions for this channel.
aw man
are there any discussions for it, tho
@ngn are there any discussions for the youtube channel?
Like the one that made the rickroll video
 
ngn
i don't understand. what discussions?
 
ngn
@MilkyWay90 i don't see any comments there
 
Okay
What do you think 0:17 - 3^7
0:29 - 2^5
0:45 - 9^4
0:06 - 3^4
0:35 - 5^4
0:18 - 4^9
0:58 - 3^7
is?
 
ngn
4:53 AM
no idea...
 
Maybe we use a youtube to mp4 and splice the video?
 
ngn
the audio is rather noisy. there might be something in that noise
 
yeah
Thats sort of what I was saying before I have a feeling there are very faint lyrics
Or do you mean something hidden in the mp4 file?
But I'm not sure whether downloading videos from Youtube is legal or not
 
ngn
@MilkyWay90 how can you watch/listen to a video if your computer doesn't download it... :)
 
@ngn True
But I meant we probably need the video file itself and open it in a text editor
 
ngn
5:00 AM
ok, i got the bytes for the audio
 
Nicr
*Nice
 
ngn
but i've no clue what to do with them
 
How?
Can you send them to me?
 
ngn
i used youtube-dl
 
via github?
 
ngn
5:02 AM
no, it was available in debian repos, but that version didn't work, so i just downloaded directly the newest version
 
I meant could you send me the mp3 file via github
 
ngn
ah
 
Also, does youtube-dl compress the video
If so, then we won't be able to find anything if something is there
 
ngn
@MilkyWay90 it's an .m4a, not .mp3
 
Oh, probably stil wil work
 
ngn
5:04 AM
these are the available formats:
$ youtube-dl -F youtube.com/watch?v=MtO589eu-Rc
[youtube] MtO589eu-Rc: Downloading webpage
[youtube] MtO589eu-Rc: Downloading video info webpage
[youtube] MtO589eu-Rc: Downloading MPD manifest
[info] Available formats for MtO589eu-Rc:
format code  extension  resolution note
139          m4a        audio only DASH audio   49k , m4a_dash container, mp4a.40.5@ 48k (22050Hz), 564.06KiB
140          m4a        audio only DASH audio  130k , m4a_dash container, mp4a.40.2@128k (44100Hz), 1.46MiB
 
Get the 44100 Hz
 
ngn
i'm not into audio processing, so i don't know how to extract the raw data from there
this is likely compressed
 
aw man
Well, let's try it anyways
So how do you get the resulting mp4 file?
 
ngn
there's no mp4
just m4a
 
Sorry, m4a
 
ngn
5:11 AM
@MilkyWay90 i put them in gitlab.com/n9n/cicada
 
@ngn Okay, i'll take a look at it
@ngn Okay have to go sleep will take a look tomorrow
 
ngn
@MilkyWay90 ok. good night
 
 
1 hour later…
ngn
6:35 AM
@MilkyWay90 i converted the .m4a to .au (with ffmpeg) and uploaded it. it turns out the .au format is really simple
 
 
8 hours later…
3:24 PM
Okay
@ngn I'm going to splice the m4a files in python according to the times in the video description.
 
ngn
@MilkyWay90 ok. you have to discard the first 32 bytes. the rest is 16-bit samples in 2 interleaved channels
 
ngn
@MilkyWay90 regarding your idea for playing the notes - we don't know which octaves they belong to either. this could be a high B♭ or a low B♭
 
right
 
ngn
@MilkyWay90 i hope you don't mind i put a transcript of your website's chat in the notes? i can revert if you feel uncomfortable with this
 
3:41 PM
@ngn That's all right
It's the public chat, so it's already public
Oof
Pydub is erroring for no reason
Do you know any solution?
 
ngn
@MilkyWay90 well, it says you don't have ffmpeg installed
 
oh
I did pip install ffmpeg and it is still not working
 
ngn
shrug i haven't used windows for the past 10 years and i have no experience with audio processing with python (or anything else)
@MilkyWay90 why not read the file directly? the format is pretty simple
 
okay
 
ngn
i have absolutely no idea how to analyse the data, but i like to have the data :)
 
3:55 PM
ok
 
ngn
so, lemme think. the rate is 44.1kHz, there are 2 channels, i want to see what's at 0:17. how many samples do i have to skip... ?
 
@ngn Yeah I've heard of cicada in the past
 
@ngn I dunno what channels are
@Quintec Yeah, they're pretty mysterious
If this is Cicada, we may use OutGuess for some of the other image files
to get more clues
 
ngn
@MilkyWay90 stereo, presumably - left and right
the samples should alternate between the 2 channels
 
ok
How many samples per seconds?
 
ngn
4:00 PM
@MilkyWay90 44100
yeah, obviously i have to skip 2*44100*17 samples :)
 
88200 * 17
1499400 samples
OOF
 
ngn
and what do i see - a bunch of numbers...
 
I think it would be best to use a software for this
Oh, you already skipped 1499400 samples?
 
ngn
@MilkyWay90 yeah, that's not very hard
 
oh
Did you use something like "goto line 1499399" or something like that?
 
ngn
4:05 PM
i guess some kind of spectral analysis / fourier transforms would be necessary... and i feel so dumb
 
same
 
ngn
@MilkyWay90 i use the vector programming language that i've been working on lately. there it's just 1499399_x
 
ngn
x_y means "drop the first x from y"
 
I have an idea
I'm going to ask on warzone.com/Forum/f8-topic
 
ngn
4:08 PM
@MilkyWay90 i don't know what that is, but go ahead
 
Yeah, some people there are smarter than they seem to be
 
ngn
we should also think about where the poem and the zebra may come into play
 
right
 
ngn
ha!! i discovered something :)
 
what?
 
ngn
4:23 PM
i searched for "whzalipu jvt" the string from the image with the flowers
 
yeah?
On the internet? or where?
 
ngn
and found some bizarre images at imgur
for example this
the comment below is in caesar7
 
Oh!
 
ngn
it's a link to pastebin.com/xdzuusn6
hehe, this is a wormhole for skipping levels :)
 
Ohh yeah I remember seeing that imgur post but dismissed it as the same link to the pastebin with the poem
I dunno, I think that we need thhe previous levels
 
ngn
4:27 PM
this is different...
 
Atbash decode?
 
I’m debating whether to work on essays or this
 
ngn
decoding with caesar7 again: "Hello, this is neb again. This time, I made this a Vigenere Cipher. To find the key, go to this video: youtube.com/watch?v=gfCbOEipZus&t and learn who tried to snap this stupid meme out of existence. By the way, the Vigenere Cipher is here: Iop, non ialiew kong tbye tvabz. turn on case sensitivity"
 
So the key is or isn’t thanos
 
Oh god
I am laughing so hard I can barely breathe
Grandayy made the meme
 
ngn
4:32 PM
what did i just watch...
is thanos the purple one with the scar-tissue beard?
 
i dont know
 
ngn
 
I'm trying to snap it out of existence but it won't go
@ngn ^
I decoded it
It says "wow, you wasted your time again"
@ngn @Quintec see above. We were fooled
 
ngn
nice :D
so it was a red herring
 
So it’s telling us to go spend time in the 19th byte :
 
ngn
what is MatPat?
 
MatPat is a YT
youtuber
 
The person who said I'm trying to snap this out of existence
And the pastebin said "The key is the person who tried to snap this meme out of existence"
 
He’s also Game theory
 
ngn
i see
 
4:44 PM
I can help decipher memes if I can’t help in any other way :P
 
@Quintec Yay
I'm gonna go to Warlight and see if I got any help yet
brb
 
I’m also on my phone... I’ll look into more detail once I get on computer
 
Okay back
People are just challenging whether it is Cicada or not
 
I would say be cations about sharing too much... maybe keep it here.... cicada got annoyed about widespread collaboration last time if it really is them
Pretty sure PPCGers contain the smartest people anyway xd
 
@Quintec Right, but it may not be Cicada
not until we find something that had to be made by Cicada
But yeah, PPCG does contain a lot of intellectually enhanced users
 
ngn
4:49 PM
@Quintec well, that's certainly helpful. i can write code to analyze large volumes of data fast, but hollywood and popular culture are foreign to me
 
@Quintec Latin may be helpful, yes
@ngn Can you update the What We Know page on GitLab with this horrendous Youtube video?
So, any ideas?
 
ngn
@MilkyWay90 maybe in a separate wiki page?
it wasn't meant to be part of the main challenge
 
@ngn Right
Anyways, let's search up more clues on imgur
 
That’s the innkeeper textt
 
4:58 PM
ohhhhhhhhhhhhh
 
I’m saying book cipher
 
Let me see if there are any books with the same name
Ughhhh
nothing works
@NGN @Quintec Any ideas?
Maybe we have to look at past clues?
@ngn 2 37 13 11 7 47 means "alfredo", we just don't know why
 
ngn
@MilkyWay90 how do you know it means "alfredo"?
 
@ngn Because all the other message names have been "alfredo"
 
ngn
the length doesn't match
 
5:12 PM
oh
 
ngn
and the fact it's all primes might have some significance
 
Well that's something we need to decode
ooh primes
2 is the first prime ("a")
37 is the 9th prime ("i")
13 is the 6th prime ("f")
 
ngn
alfedo
 
*aifedo
Right?
or did i count wrong
 
ngn
 
5:18 PM
let's go see if this has any other use for other clues
Maybe see all the primes in the pastebin?
@ngn nevermin
@ngn My suggestion is just to randomly try new encryptions
Got tog o make breakfast bye
 
@MilkyWay90 the text I linked should be from a book
Doesn’t it say which one
 
ngn
@Quintec annoyed? how did they show that?
 
@ngn messages to the participants in the global coordinate hunt
Ive followed cicada for a while xd
 
ngn
5:35 PM
it's not entirely unpredictable that public collaboration will happen...
 
@ngn Maybe
Okay, I think we are stuck
We are probably looking for a link
 
Can i get a list of all leads that we don't know the meaning of
Or maybe put that at the top/bottom of the gitlab
 
ngn
@Quintec just search for "unknown" in the wiki's home page
 
ok
 
ngn
i need to update it with the discovery about primes
 
5:51 PM
Does anybody know a regular expression to detect links?
This is what I have so far: [a-z][0-5]\.[a-z][a-z][a-z]
 
the link i previously posted, [coursehero.com/file/8027418/Latin-2-Yr-translations/](this) is definitely from a book, it's used for latin translations everywhere,found it 10 times on quizlet
but i can't find the source
 
ngn
gtg, see you later
 
k bye
 
 
3 hours later…
ngn
8:56 PM
random thought: start a recruitment agency. post many challenges like these all over the web. at the final stage invite the best solvers for an interview with your clients => profit :)
