MotD ADFGX Riddle

Hey everyone. So the Mob of the Dead 6 minute trailer (Which was amazing) released and in it we saw what is believed to be the loading screen that included a bunch of letters consisting of ADFGX.

Here is the combination of letters as it appears on the loading screen.

FFGXGD
GFFAGF
GGDDGF
FFXXFF
FDGFFG
FDGFFG
FDGGFF
FGFGAA
FXFXDX
XFXDGF
FAGGFF




AF

So this can easily be determined to be deciphered using the ADFGX Cipher.

So there are two things needed in order to decipher the message using the ADFGX Cipher. We need to know a keyword but more importantly we need to know the matrix alphabet order.

I posted this video to kind of help those who are attempting to solve this.


So assuming that I haven't made a mistake thus far (in regards to the video) we can determine that the key will be one of the following:

fedcba
fedbca
fedbac
fedabc
fedacb
fedcab
fecdba
fecdab
fecbda
fecbad
fecadb
fecabd
febdca
febdac
febcda
febcad
febadc
febacd
feadcb
feadbc
feabdc
feabcd
feacbd
feacdb
efdcba
efdbca
efdbac
efdabc
efdacb
efdcab
efcdba
efcdab
efcbda
efcbad
efcadb
efcabd
efbdca
efbdac
efbcda
efbcad
efbadc
efbacd
efadcb
efadbc
efabdc
efabcd
efacbd
efacdb

However this is of little use to us if we don't know the order in which the alphabet lies in the 5X5 matrix. So that is where I am coming to the community to work on this. If you have any questions or notice anything wrong please let me know and Ill do my best to help.

Here is the cipher text to decode:

FGGFFFFFFXFFFGFDDDGXFAGFDXGGGFFXGADXFFGGXDGGGGFFFFADGFADFFFGGFAXFFF

Hey good info.

But I'm not sure why you are using those letters for the key.

There was an earlier post with some info that might help you:

I explained it in the video but Ill explain it here as well.

The actual word itself doesn't really matter. The only thing that matters is the position of the letters alphabetically. So from looking at the given code we see "A" and "F" are in the last collumn. What that means is that since that is the alphebitized format we see that the last two would have had to be in the front (because they have the A and F) and since they are positioned in the back we know that those two are higher up alphabetically than the other four. So with that information (which I just re-read and.. well good luck understanding) you can come up with every variation that would match the given code. Which are those 48 keys.

I ran this idea through an adfgx cipher solver using each possible keyword, then ran each answer through a substitution cipher solver. Unfortunately, there were no good results. All I kept getting was strings of random words. It was a good idea though.

I think the decoded message is still coded, like a cryptogram. I messed around with it for a good bit and couldn't get any combination to look like real words, so there must be a way to decode it after we solve the cypher. So its probably almost impossible to solve without a keyword.

Please define "each possible keyword" ... because that's ^^^^  a pretty bold statement right there

Have a look at the original post. Going by his theory, there are only a handful of possible keywords, which he has listed. The actual keyword doesn't affect the outcome. It's only the order of the letters alphabetically. The keyword ZOMBIE would give the same result as FEDACB. I just tried each keyword in the OP and ran the result through a substitution cipher to get around the possible custom polybius matrix.

I have been playing around with this for days now... I have an image of the 'Escape Plan' that clearly says at the top 'Remember this AL dont forget'

Also the left page states 'A Cat Has 9 Lives' other than that we have several 6 letter words such as Island that do not contain any of the same letters.

The thing that caught my eye the most was the AL bit in the top of the right page. This is not a simple spelling error, I am certain that it is referring to AL CAPONE as he was imprisoned in Alcatraz.

I have also tried using the Mob of the dead in the alphabet as per the requirement mobfthedacgiklnpqrsuvwxyz.

Anyone been thinking along these lines??

sorry to say this but your wrong 2 factors but on the right lines for the key word.

1st of the text is still in table form and hasn't gone through the last encode'n step, mean it reads left to righ, not top to bottom.

secondly your using the decoder wrong, if you put all the code in it will come out like this (numbers represent columns) 1111112222223333344444445555556666666 when you want it to be 123456123456 etc, solution do it one line at a time.

heres a couple of polibus input codes iv used

motb code (a starts at the bottom and and continues at the top)

FGHJKLMNOPQRSTUVWXYZABCDE

Spiral code (a starts at bottom and spirals round)

NMLKJOXWVHPYZUGQRSTFABCDE

motd codeII (a starts at bottom but the nxt line above it)

VWXYZQRSTULMNOPFGHJKABCDE

hope this helps someone
