There were 3 codes found on PAC’s Weekly Wrap-up post for April 10, 2016 on the Investigation Blog.

[1] #%$&%)$*#$$%#^%)#^%^
[2] lojlvlyr.rzbollpy
[3] 5664277766685664339911233393335776668222


Code #1

Observations

The length of the code has an even number of characters, so looking at pairs of characters for a clue:

#% $& %) $* #$ $% #^ %) #^ %^

There are 10 groups, which could match a prefix/suffix pair with an unknown keyword. Assuming the first 5 pairs are the prefix and the last 5 are the suffix, we see that the positions where the numbers would be all have # as their first character.

[hint]

Convert the symbols to their QWERTY keyboard equivalent:

35 47 50 48 34 45 36 50 36 56

[/hint]

Code #2

Our thanks goes out to kon5000 for giving us “pointers” to the keyword.

Observations

Looking at the code and trying the standard methods does not reveal much, except that the . seems to be in the spot of a keyword.

[hint]Since there are no numbers in the code, try transforming the letters into something else.
[/hint]

Code #3

Observations

The letter distribution appears random but there is a disproportionate amount of repeated numbers.
