Hey,
As a quick sanity check. You can run the following:
vol.py -f <> --profile=<> yarascan -y "Copyright (c) 1992-2004" -K
This will have yarascan look for the string in kernel memory and report
back the address for any hits. Can you paste any hits you get from this?
This should help us determine if there is a bug in strings.
Also, since I am late tot he thread... This is a raw dump right or a
dump that was converted to raw with imagecopy?
Thanks,
Andrew (@attrc)

Thanks gentlemen. No worries there. I didn't take

Correcting the command gives me output, but leaves me with a new
question. The string of interest seems nowhere to be found (maybe it's
unicode? I'm not sure how to tell...):

Your command:
db(f9805ba44800)
The missing 0x in front makes Python think
f9805ba44800 is a
variable name rather than a number.
