Hey Tom,
Thanks for the update and helping us investigate issues in the 2.1 alpha
branch. It sounds like DumpIt produces dumps from win7 x64 that work with
volatility, but FDPro does not -- even though FDPro produces dumps from xp
that work with volatility. Is that an accurate summary?
Did you run FDPro on the same machine as DumpIt?
Although both tools output a DD-style dump, the way they acquire the memory
to put in the dump is sometimes drastically different (for example FDPro
has the "smart" feature that probes pages back into RAM etc). So the
difference you're seeing is not totally surprising, but the question is -
can we figure out what's different in the FDPro dump and somehow account
for it.
If imageinfo says "no suggestions" its because the KDBG scan failed. I'd
like to find out if that's because volatility's KDBG scanner is flawed or
because the KDBG signatures are truly not present in the memory dump.
Hopefully you can use the attached yara ruleset (get yara from
) for testing. Use it like this:
$ yara kdbg.yara memory.bin
My guess based on what I've heard is that you'll get results for the dump
produced by DumpIt but not dump produced by FDPro. Can you try that and let
us know...then we'll try and figure out the next steps? If the FDPro dump
doesn't contain a KDBG signature, we'll have to figure out if its an error
in FDPro (failed to acquire that segment) or an error in volatility
(perhaps we have an incorrect signature).
Thanks Tom!

Ok an update....so I ran the FDPro dump against 2.1
alpha and I'm getting:
Volatile Systems Volatility Framework 2.1_alpha
Determining profile based on KDBG search...
Suggested Profile(s) : No suggestion (Instantiated with no
profile)
AS Layer1 : FileAddressSpace (memory.bin)
PAE type : No PAE
Now what's odd is the FDPro output is a raw DD image. And I've run it
against XP machines without any problems in Volatility.
I also did what MHL suggested and ran:
python vol.py -f memory.bin --profile=Win7SP1x64 pslist
and got this (which I was expecting since I didn't get a "response"
from imageinfo):
Volatile Systems Volatility Framework 2.1_alpha
No suitable address space mapping found

I'm still going to run some other tests (standard Win7 image, run the
dumps through *nix "version" of Volatility, etc).

MHL,
Sorry I got the same output with both the 2.0 stable and the 2.1 alpha
branches.
However, I just ran the imageinfo of the DumpIt DD image on the 2.1
alpha branch, and I did get output:
Volatile Systems Volatility Framework 2.1_alpha
Determining profile based on KDBG search...
Suggested Profile(s) : Win7SP1x64, Win7SP0x64,
Win2008R2SP1x64, Win2008R2SP0x64
AS Layer1 : AMD64PagedMemory (Kernel AS)
AS Layer2 : FileAddressSpace (memory.raw)
PAE type : PAE
DTB : 0x187000
KDBG : 0xf80002bfe0a0
KPCR : 0xffdff000
KUSER_SHARED_DATA : 0xfffff78000000000L
Image date and time : 2012-03-07 15:59:22
Image local date and time : 2012-03-07 15:59:22
Number of Processors : 4
Image Type : Service Pack 1
So that worked. I'm trying it again with the FDPro dump, which is a
DD image dump as well. I'll reply back when I get results from that.
I'm guessing it should work but we'll see.
My guess (as someone else suggested to me) is I may need to collect
the memory dumps with EnCase without compression and then either mount
them with mount_ewf.py or convert them with FTK Imager and test that.
What's odd is I did a test on a Win7 64-bit machine I have at home
(E01->DD) and it worked fine.
Thanks,
Tom
