Looking inside the source of the “Brooklyn: The Suspects” post over on the Investigate Ingress blog, we can find two codes hidden in the source and one in the image of the post:
If you are good at math, you might find some character in the numbers

Primes matter

Lets seperate the code by ‘&’ 17m691m7212698459 3p3m2468802436547 2p2m3m281m23083330619
You may notice that all numbers are primes.
Substituting ‘m’ with ‘*’ and ‘p’ with ‘^’ gives
17*691*7212698459 3^3*2468802436547 2^2*3*281*23083330619
Calculate each block (note that power should be calculated first, e.g (3^3)*2468802436547 = 9*2468802436547 )

Code #2
Observations
We have an interesting code of alternating letters and numbers.
This normally means that we could split the two for two different parts of the solve.
Remember that if the original string itself was longer, that that might hint at there being two codes hidden in it.
[hint]
Solve numbers first, that is the key ingredient to solving the letters.

Splitting the letters and numbers, we end up with this: 94848797775686 fuovapblogosqq
Let us solve the numbers first.
They seem to be almost in a decent range when paired up, but not quite there, instead reverse them first (shown here after pairing) 68 65 77 79 78 48 49
Convert from decimal to text DAMON01
Reverse this 10NOMAD
Now somehow, 10NOMAD needs to refer one to the keyword of mystic. If you happen to know what links these two, let us know.
But since we could not find any concrete direct referencing, Kokuryuu did a Vig brute with all the keywords to find it.
Because the numbers section gave us a keyword, we know that the letters section should then be the pre-/suffix, we take the result of the Vig for our next step twwcsnipsewfib
Replace the written numbers to show us the pre-/suffix 2wcs9p7w5b
Add everything together for the final solve. 2wcs9mysticp7w5b
Code #3
Observations
Here we have a code preceded by + and followed by -, this is a good indicator that something should sometimes be positive and sometimes negative.
[hint]
Look a bit further into the normal “try these first” ciphers.

Spoiler
Running the text through the normal, all possibles of ROT, we can see something intriguing with the first and last one. ROT +01: vhtegtszuizpteuqwexuaekgjtefkvgb ROT +25: tfrcerqxsgxnrcsoucvsyciehrcditez
See that if you were to take alternating letters from each line, we get spelled out numbers?
Remember that ROT +25 is the same as ROT -1, which links back nicely to the given hint.
Reading the lines, starting with the ROT -1 and alternating between them, we get threetqzsixpresquevuyeightcfiveb
Substituting the written numbers gives us the final solve 3tqz6presquevuy8c5b
