Three codes appeared hidden throughout the Disaster Strikes post on Investigate.Ingress
[1] 5u3nomad4k7w

Code #1

Observations

Exactly 4 numbers in the string, however it does not match the passcode pattern.  There is also a possible keyword substitution in the center of the string.

Code #2

Observations

Numbers, letters and weirdly one capital letter. Maybe there is too much noise in that code !

Code #3

Observations

The passcode format is there, just need to find the right transformation.
