Who is Jahan?

There were 3 codes found in the Who is Jahan? blog post on the Investigation Blog.

[1] 6xbc8cb6g2t
[2] 4uv3lkktg9rj6am
[3] gyfdd645gyfddfdwgfqk6grrk4d3dktygs

Code #1

Observations

The code looks like it’s in the passcode format, so we just need a keyword substitution for c.

Code #2

Observations

The length of the code is 15 characters, which has factors of 3 and 5:

4uv
3lk
ktg
9rj
6am

[hint]

We see ultra in the middle column but reading vertically down from the top-left has too many numbers in the prefix and no numbers in the suffix.

[/hint]

Code #3

Observations

On first glance, it looks like the distribution of characters are somewhat clustered:

DFGK QRSTWY 3456

[hint]

3456 is on the top row of a QWERTY keyboard

QRTWY is on the 2nd row.

DFGKS is on the 3rd row.
