Just tried the 2.1 RC3 version and got the errors below. Then did the 'python setup.py clean' command followed by repeating the install command 'python setup.py install'. Still no difference. No errors produced during install. Egg was built and copied. Using Win7 and Python 2.7.3.

no conf-file option in Vol 2.0

by Skippy VonDrake

Using help on the command line I see no reference to the "--conf-file" option. Was it removed?

Volatility 2.1 RC1 is available

by Michael Hale Ligh

Hey everyone, The 2.1 RC1 downloads are now available [1]. Per the usual, there are zip and tar archives of the source code, a windows module installer, and a standalone windows executable (with python and all dependencies build-in). We ask that you test vigorously over the next 2 weeks, especially with any x64 images, and let us know via the issue tracker [2] if you run into any bugs. At the end of July, we'll announce the official release of 2.1. Also, a lot of the documentation [3] has been updated, including the FAQ, command reference, features by plugin matrix, and roadmap, so that may be a useful resource to you when using 2.1. Thank you very much! [1]. http://code.google.com/p/volatility/downloads/list [2]. http://code.google.com/p/volatility/issues/list [3]. http://code.google.com/p/volatility/w/list

got a rootkit or what?

by phocean

Hi list, I believe that one of my lab VM is owned by a sophisticated rootkit. There are many signs of that: Rootkit in my lab? Rootkit in my lab? (part II) Live analysis was a dead end. Needless to say that common live analysis tools and AV found nothing. So I have been focussed for days on analyzing the RAM with Volatility. And I found absolutely nothing. I am just afraid that now it is beyond my skills at this moment. If some of you are curious, do not hesitate to have a look. Of course, I would love to learn more and get some tips and feedbacks. I can provide more volatility output if necessary, or even the dump. Thank you! --- phocean

Impact on memory images when suspending a virtual machine

by Stefan Vömel

Hi everyone, in prior threads, Michael and Aaron pointed out changes in memory structures when suspending a virtual machine. I think this is an important observation and would therefore suggest moving the respective discussion to a separate thread. I have summarized the relevant passages below. ---- Michael H. Ligh (http://lists.volatilityfoundation.org/pipermail/vol-users/2012-June/000441.…) > Also, if you're analyzing a memory dump by suspending the VM, that has > significant impact on the lifetime and availability of network > structures. When you suspend/pause a VMware guest, VMware tools runs a > bat script on the guest (I think its vm-suspend.bat) which forcefully > closes TCP/UDP and frees the IP. Jesse Bowling (http://lists.volatilityfoundation.org/pipermail/vol-users/2012-July/000470.…) > This was a VMWare 4.1 virtual machine that was paused, and the vmss file > copied out. > Much later I head referenced that pausing the virtual machine actually > causes a lot of information to be removed from memory due to the way VMWare > prepares the OS to pause... :( (Can you or anyone speak to the truth-iness > of this?) AAron Walters (http://lists.volatilityfoundation.org/pipermail/vol-users/2012-July/000473.…) > This is definitely something to take in consideration with this particular > acquisition method. I think you are referring to a comment that MHL made > previously about vmware tools. A similar thing happens when people > attempt to use hibernation files. Intuitively, what does it mean to resume > a network connection that disappeared hours, if not days, earlier? In some > instances, it is possible to still extract associated artifacts from > unallocated regions, a technique most debuggers don't handle very well. ---- Last year, I wrote a survey article about memory acquisition and analysis techniques (http://www.sciencedirect.com/science/article/pii/S1742287611000508) and stated in a short section about virtual machines that, by suspending a system, a memory snapshot with a high level of atomicity and correctness could be produced. With respect to the issues raised by Michael, this statement is maybe a bit too optimistic now?! I have recently done a lot of research in the area of memory acquisition, specifically with regard to software-based utilities. We have tried to formalize criteria for sound memory imaging in a different paper (http://www.sciencedirect.com/science/article/pii/S1742287612000254) and I'm currently working on a platform that may help evaluating the correctness, impact, etc. of a utility more accurately. As the discussion about virtual machines roughly touches my research interests, I would like to know if there's any more information on this topic. Specifically: - Has anyone ever measured the impact on a memory image when suspending a system? - I have briefly looked at the vm-suspend-default.bat file which is located in the folder of the VMware tools. It just includes an "ipconfig /release" command, so it appears "only" network-related information would be affected. Is anyone aware of any other structures that would be changed/destroyed when going into suspensed mode? - Is the batch script (or similar operations) actually executed every time a machine is suspended? I have just run a quick google query on the file and only saw that its use was optional? I would very much appreciate if anyone had some more details on this or could share some references. Best regards, Stefan
