Hey Jon,

psscan, modscan, driverscan, filescan, mutantscan,
symlinkscan, thrdscan,
and netscan produced no output other than the header.
So the main three reasons I can think of for these scanners failing are:
1) the image is corrupt (i.e. the acquisition tool didn't capture several
areas of memory)
2) malware modified pool tags (i.e. DKOM)
3) the wrong profile is being used
So they are all possibilities, but let's discuss their likelihood. #1 is
unlikely IMO because kdbgscan was able to print lines like these:
Service Pack (CmNtCSDVersion) : 1
Build string (NtBuildLab) : 6001.18000.x86fre.longhorn_rtm.0
Those values are extracted from the ntoskrnl.exe kernel driver, which means
at least one module is in memory...yet modscan doesn't pick it up. #2 is
unlikely because malware that uses DKOM typically does so to hide an
individual process, not overwrite an object's pool tags (although its
possible). Plus I'd expect if malware did overwrite pool tags, it would do
it for certain objects only (i.e. just processes and threads or just
network objects) and not all tags associated with all objects. #3 is
unlikely - we know from kdbgscan output that its SP1 something. We know its
x86 and not x64 because kdbgscan is able to find a valid DTB. Out of the
kdbgscan suggestions, you've already tried both VistaSP1x86 and
Win2008SP1x86 and neither seemed to work.
So pretty strange, I don't know what the problem is at this point. If its
just a testing/training image (i.e. doesn't contain sensitive information)
and you can share it with the volatility dev team, we'll be glad to take a
look and report back what we find. That would reduce the number of emails
back and forth and is probably your best bet to figuring it out. If you
want, we have private drop boxes where you can upload the image and it will
only be accessible by a few devs. Let me know.
impscan, svcscan, and cmdscan all returned errors.
That makes sense. Although they have "scan" in the name, these three
plugins scan process memory as opposed to the ones you listed above
(psscan, modscan, etc...). Thus if no processes can be found (i.e. pslist
fails) then all 3 of these will fail with the same error.
hivescan returned a bunch of offsets with no other
info
That's OK. The output of hivescan is supposed to only contain offsets. See
[1]. Perhaps you could try hivelist which lists the offsets plus the path
to the hive. See [2].

Cool, no worries. I'm guessing it was missed
in the crossfire.
Just looking at your directory listing I might have guessed it was
FTK: G:\FIWE-Scenarios\Final\AD\RAM\10010AD.dd
of course I could be wrong since "AD" may refer to something else...
Try as many "scanning" plugins as you can muster and see if anything
comes out while we think of something else. BTW, we aren't helping
you cheat are we? ;-) The thought occurred to me that this sample
could be intentionally broken.

The answer to that question was in previous email
where I posted the
entire
kdbgscan output. I believe the mdd was used to
acquire the image.
