Hallo!
I'm currently working on a forensic aquisition tool to get live data from a running system. I want to extend the tool with volatility and therefore make the tool independent from an installed python on the system volatility is executed. What's the best possibility to have a "mobile" volatility? I tried py2exe but it is not trivial to include all the needed modules and dlls needed to run volitility correct. Currently the volatility-exe created with py2exe is only running when python is installed on the system. Has somebody a better idea to create a mobile volatility or a setup.py for py2exe that works?
best regards
hermann

Perhaps I'm off target here. I know that I was successfully obtaining
open ports and IP addresses from my memory dumps before. But I haven't
seen any output from the connections module or sockets for the last
while.
I have compared the results using the same image file, in
Memoryze/Audit Viewer and am getting the correct network info.
I'm wondering if this is a result of SP3? Or have I missed something.
Thanks.

Hi Brian,
There is no such thing as a stupid question; don't worry. To my knowledge nobody
has published much information about doing memory analysis on 64-bit systems, so
the following is mostly conjecture.
When working in 64-bit mode Intel processors use a different method of
translating the virtual addresses used by programs and the operating system into
the physical addresses in RAM where data really lives. As such there are going to
be several differences in the operating system for a) keeping track of where data
lives and b) virtual to physical address translation. You can read much more
about these difference in the Intel Architecture Software Developer's Manuals,
http://www.intel.com/products/processor/manuals/. BTW, Intel will mail you hard
copies of those books for free. Really! As many as you'd like of whichever ones
you'd like. Enjoy!
As for the differences in anything else, like I said, I don't think anybody has
published on those yet. You could be the first!
cheers,

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.

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,
