Hi all,
Forgive me if this is a stupid question, i'm a bit new to physical memory
analysis.
Is the structure of physical memory on a 64bit operating system different
than that of a 32bit operating system, and if so does volatility have the
capability to parse 64bit images?

One of my students noticed this as well. I had asked her to send me
the error message, but I guess she forgot... After she commented out
that line it worked fine.
All the best,

I am trying to develop a step-by-step guide for installation and use of
Volatility and Python in *Windows* as many of our users have a different
knowledge level.
I was wondering if anyone has any "best practice" guidelines for:
1. If you install Python, would it be preferable to change the Path in
Environment Variables to allow Python to be recognized by any directory?
2. Where should I install Volatility to (Python directory, it's own
directory)? Should this directory be "pathed" as well? I am trying to
reduce the complexity of the command line to run the program.
3. Is if preferable to have the memory image in any specific directory?
4. I am getting a warning, although can still get an output. The error is:
"c:\python26\forensics\win32\crashdump.py:31:31: DeprecationWarning: the sha
module is deprecated; use the hashlib module instead
import sha "
Any guidance would be appreciated.

Hi,
when running
python volatility files -f ../mem.dd
I get a correct looking result for the first 8 processes, then I get the
following error:
<-------------------------------------snip

The operating system in the image is a XPSP3, volatility ident shows:

Any ideas what could be the problem ?

I'm trying out Volatility 1.3 Beta on Linux (RedHat Enterprise 5).
I quickly encountered a problem as follows:
[root@HX80722V1 Volatility-1.3_Beta]# python volatility
Traceback (most recent call last):
File "volatility", line 37, in ?
from vmodules import *
File "/usr/local/src/Volatility-1.3_Beta/vmodules.py", line 1938
finally:
^
SyntaxError: invalid syntax
The md5 checksum is correct for the downloaded file.
Is there a fix for this ?
Thanks !

Hi everybody,
Jun asked me about a paper I wrote and which Harlan's tools were
based. Although I can't send out the full paper, I can show you a
slide from my talk at the 2007 DoD Cyber Crime Conference athttp://jessekornblum.com/tmp/determine-os.pdf
. The slide shows how you can use the spaces between known values, in
this case between the Eprocess header and the name of the process, to
identify what OS you're working with.
For the record, Volatility looks at each process' Peb, IIRC, which in
turn contains a string naming the Service Pack number. The framework
records how many processes indicate which string (e.g. 7 say "Service
Pack 2" and 2 say (null)). The string encountered the most times is
displayed.
cheers,

Hi,
Suppose that I have a raw memory image of a particular Windows
machine. Is there any way to determine its version? It can be W2k,
WinXP SP2 or SP3 or Vista.
Perhaps we can look into some places into the image to get those
information out?
Thanks,
J
Hi,
I am interested in working with the experimental version that supports Linux memory images and integrates with PyFlag. I would greatly appreciate a copy of the source code with those features (e.g. the version used in the DRFWS 2008 challenge).
Thanks,
Sam
Hi everybody,
Here's a Volatility plugin to first recover the command line for each process and
then find any suspicious ones. I wrote it to get a feel for the framework's
Object model. Please note that the current version of the framework has a (soon
to be corrected) bug that can result in a crash. Don't panic!
The plugin considers a command line to be suspicious if it contains the word
"TrueCrypt" or if it starts with a lower case drive letter. The latter is
indicative of a manually typed command line. I've found it handy to examine
TrueCrypt command lines because they can contain the filename of a mounted
protected volume.
cheers,

Attached please find a Volatility plugin to scan for TrueCrypt passphrases using
the method described in Brian Kaplan's thesis, 'RAM is Key, Extracting Disk
Encryption Keys From Volatile Memory', pages 22-23. You can downlaod the thesis
at http://www.andrew.cmu.edu/user/bfkaplan/.
Usage:
python volatility cryptoscan -f [FILE]
The output will look like:
Found TrueCrypt passphrase "8964h khI@*TGUIG!!" at offset 0x65f8094
