Three codes were found in the Declassified Aegis Nova Anomaly Intel post on the Investigate Ingress blog.
[1] 030650650638405073018520292040X06301630649407I
[2] cvzgsom9kcou25c3
[3] $1.00 - $0.68 $0.26 $0.33 $0.24 $0.62 $0.23 $0.65 $0.34 $0.64 $0.28
Code # 1
Observations
Not much to indicate what cipher was used, go through some usual ciphers to see if you can find a pattern.
[hint]- – A regular cipher but used differently . .[/hint]

Not to sure where to begin when I first saw that code but because of the number and letter combination I suspected some kind of morse manipulation. Here’s the string converted to morse
----- ...-- ----- -.... ..... ----- -.... ..... ----- -.... ...-- ---.. ....- ----- ..... ----- --... ...-- ----- .---- ---.. ..... ..--- ----- ..--- ----. ..--- ----- ....- ----- -..- ----- -.... ...-- ----- .---- -.... ...-- ----- -.... ....- ----. ....- ----- --... ..
Notice how it starts with 5 dashes? Numbers in Ascii are in the 48 to 57 range. Let’s try grouping in pairs alternating between dashes and dots and then counting the dashes and dots to form the numbers
-----...53
--------.........89
------.........69
------.......67
-----......56
------.....65
-------......76
-------.71
-------.........79
--------..82
-------...73
--------....84
-------..72
-------.......77
-------.71
-----.......57
--------........88
-----.....55
--------.....85
We now have a valid Ascii string
53 89 69 67 56 65 76 71 79 82 73 84 72 77 71 57 88 55 85

Code #2
Observations
All the ingredients for a code, looking for a 6 letter keyword
Spoiler
16 characters, the four numbers for the code are there. Make a 4×4 grid

Code #3
Observations
Seems like we need to play cashier !!
[hint]For the sub, think about what’s left in you pocket[/hint]
Spoiler
The $1.00 – gives you what operation you need to do. From $1.00 subtract every value
$0.6832
$0.2674
$0.3367
$0.2476
$0.6238
$0.2377
$0.6535
$0.3466
$0.6436
$0.2872
You are left with a valid Hex string for a code

For the keyword, think about what we just did. You gave $1.00 to pay for an item that was $0.68, the cashier gave you back $0.32 of “change”.
