Hello,
I hope someone can help with this.
I am attempting to perform live memory analysis on linux virtual machines
using Xen, LibVMI and Volatility.
The command I am attempting to run is:
# python vol.py -l vmi://ubuntu-pvm-01 --profile=Linuxubuntux64 linux_psaux
I created the profile Linuxubuntux64 using the instructions on the
Volatility linux plugin page
I have included the pyvmiaddressspace.py file below:

I added the print statements to see if the addressspace plugin was
obtaining any information at all, because without them the only output was:

I am only just getting to grips with using Volatility so any advice as to
how to debug this issue would be much appreciated.

I am looking for an Android memory image to use Volatility on. Does anyone have (or know where I and get) a memory image I can look at?
If you are imaging Androids, can you reply offlist?
Thanks! Have a good week!
I've put together a package for you, http://michael-lambert.us/Rocra_130115b.zip
In it is the memory image, 130115b.w32. Infection time is approx 1637 CST on 15 Jan. svchost.exe PID is 464, parent is msmx21.exe PID 1404
Also included is the DOC file that drops and runs msmx21.exe which drops and runs svchost.exe
Thanks for looking at it.
Is anyone else looking at Red October?

I got the exe from your website, thanks. Do you happen to have the original malware sample, or an md5 of the sample. There are a few things I'd like to check out that may be easier if I had a full memory dump.
Thanks, talk to you soon.

Mike, if you could use dlldump and extract kernel32.dll from pid 464 and send it to me, I'll take a look. The necessary pages of the PE file may just not be memory resident.

Gmail does pretty deep inspection of attachments, in this case
noticing a .exe file in the header of the ZIP archive:
$ zipinfo Rocra_svchost-exe_464_exe-dump.zip

2 files, 71471 bytes uncompressed, 29202 bytes compressed: 59.1%
I tend to strip extensions and send in encrypted zips when dealing
with Google services. Fantastic for everything except threat sharing.

Hmm sorry, I must be reading the GMER log incorrectly:
IAT C:\Program Files\Windows NT\svchost.exe[464] @ C:\Program
Files\Windows NT\svchost.exe [KERNEL32.dll!GetFileType]
E80C244C
I thought that was saying functions in kernel32.dll's IAT were hooked, but
I think its saying the IAT entries in svchost.exe for kernel32 APIs are
hooked. So in that case I'd need you to use procexedump -p 464 and send the
extracted svchost.exe.
Also if that number at the end (E80C244C) is the address of the hook,
something is seriously wrong because that's an address in kernel space.
Hooray for log files with no meaningful labels ;-)

Hello All,
We were writing to announce the first annual Volatility framework
plugin writing contest:
http://volatility-labs.blogspot.com/2013/01/the-1st-annual-volatility-frame…
This contest is modeled after the well-known Hex-Rays plugin contest,
and we hope to attract the same level of high-quality submissions as
seen in the IDA contests.
To the winners we offer a variety of cash prizes, recognition, and a
chance to speak at our yearly conference.
If you have any questions or comments please contact me directly or
use the contact information listed in the blog post.
Thanks,
Andrew
All,
So over the course or Luka's thread on his research the subject of testing
your acquisition tools came up.
I know this topic has been mentioned before (in one of my own past posts),
but what is the requirement for memory acquisition tools to be working
"properly"? Especially since each time you run the test against a memory
image that image has changed.
What steps, at a minimum, should you be making sure that the tool you are
using/evaluating is doing what it should be doing? Listing processes
correctly? Showing the correct artifacts if I have Zeus on the image?
The topic always seems to come up (even with physical devices) that you
have to test your tools, with no one ever saying what checkmarks you have
to make sure the tools does.
Thanks,
Tom
