6 p.m.
I have a text string that I found in memory and I would like to find out what is
using/mapped to that address. (a process, a dll, a buffer, unallocated, etc.)
How do I do that? I'm exploring the docs to see how close I can get; for example
dumping what I can with memmap, and then searching for my physical offset. (but that only
gets me processes)
Any suggestions appreciated.

Mike,
You can try the strings command:
http://code.google.com/p/volatility/wiki/CommandReference#strings
Since you know what string you're looking for, and assuming you don't
find it in process memory with vaddump or memdump, you could also
write your own plugin that does something like this (assuming x86):
CHUNKSIZE = 0x100000 # 1 MB
for addr in xrange(0x80000000, 0xFFFFFFFF, CHUNKSIZE):
data = addr_space.zread(addr, CHUNKSIZE)
# test if your strings are in data

Hi Mike,
I did try strings.
My string input file (120129Nbivevokoxa.txt ) looks like this
192480a0:Nbivevokoxa
My commandline was:
C:\Python27\volatility-2.0>python vol.py strings --profile=WinXPSP3x86 -s
\mem\120129\120129Nbivevokoxa.txt -f \mem\120129\120129c.w32 --output=text
--output-file=\mem\120129\120129strings.txt -S
Volatile Systems Volatility Framework 2.0
ERROR : volatility.plugins.strings: String file format invalid.
What should the contents of 120129Nbivevokoxa.txt look like?
Thanks,
Mike

I'm afraid the strings plugin only accepts decimal offsets, rather than
hexidecimal offsets. Please run strings using -td, or just change your
one example to "421822624:Nbivevokoxa"...

Thanks Mike!
HaHa! I was searching a memory image with Encase. Encase gave me a decimal offset into the
memory image.
For some reason I thought I had to convert it to hex. Looks like the joke was on me!
Works great, thanks for pointing out my error!
BTW, what is "... using -td, ..."? I don't see -td mentioned in -h or the
docs online.
I'm using http://code.google.com/p/volatility/wiki/CommandReference and the -h
command, is the more docs somewhere else I need to be looking at?
Does anyone live in Houston?
Best,
Mike

Glad you got it all working. 5:)
BTW, what is "... using -td, ..."? I
don't see -td mentioned in -h or

Sorry, it's a command-line switch for the linux "strings" utility, which
is what is usually used for generating the input files for the
volatility strings plugin. I hope that makes sense, there's a few too
many things called "strings" flying around... 5:)

Mike,
You could also use the pas2kas module:

I did figure out one way to do this, and it works if the memory block is used by a
process.
I used memmap and dumped every processes to a text file. I then used notepad to search for
my physical address (and found it). The I just page-up until I see that process name.
It would be really cool if there was a switch that would change the output from:
smss.exe pid: 724
Virtual Physical Size
0x0000100000 0x00090b6000 0x000000001000
to:
Virtual Physical Size Process PID
0x0000100000 0x00090b6000 0x000000001000 smss.exe 724
Then you could put it in a spreadsheet, sort on physical address. You would then have a
great guide to reference when you were exploring the memory dump with Encase or a sector
editor (looking for interesting addresses or strings). I do this frequently.
Best to all,
Mike Lambert

I updated our documentation to make it clear that decimal offsets are
required, and we'll give your suggestion below some thought before the
next major release of Volatility
