Three 2014 Volatility & Memory Forensics trainings are now scheduled

by Andrew Case

As we previously sent to the list, the Volatility team will be holding training sessions in San Diego in January and London in June: http://volatility-labs.blogspot.com/2013/09/2014-malware-and-memory-forensi… We have now also finalized plans for a training in NYC in May: http://volatility-labs.blogspot.com/2013/10/2014-malware-and-memory-forensi… These will be the only public trainings through August of next year, and we have already received substantial interest in each one. If you plan to attend do not wait until the last minute to contact us as for our last several trainings we have had to turn away people once the classroom fills. If your company is interested in a private training or hosting a public training in exchange for a few free seats then please let us know ASAP as these opportunities for 2014 will likely be taken by other companies over the next month or two. Finally, the Volatility team would like to thank everyone who came out to OMFW and to those of you who attended our OSDFC talk and showed support for the project. Over the next couple weeks we will be sending out slides and updates from OMFW, and please reach out to us if you have questions for any of the speakers that you did not get to ask in person. Thanks, Andrew (@attrc)

New plugins: Filelist and Virustotal

by Sebastien Bourdon-Richard

Hi, Based on the work AAron and the Volatility team have done for the dumpfiles plugin (thanks for the plugin btw), I have wrote two new plugins for Volatility. I have coded those plugins to learn more about the new dumpfiles plugin. I'm sharing them hoping they will be useful for someone else. The first plugin is filelist. It is used to list files that can be extracted by the dumpfiles plugin. The second plugin is virustotal and it is used to query/submit cached memory files to virustotal. Both plugins can be downloaded here [1]. Here's some examples on how to use the filelist plugin. Memory sample [2] was used for the examples.

probably a really dump question RE: the new dumpfiles plugin

by McCash John-GKJN37

Hi, I'd been looking forward to the new dumpfiles plugin for a while, so I immediately downloaded it and tried it out as soon as possible after I saw it had finally been committed to the source tree the other day. (I'm freely admitting I'm using the thing without any documentation, since that still hasn't been committed, and probably have no idea what I'm really doing.) Now, I have a dumb question. The names of the dumped files are all of the format: file.<number>.<hex number>.< dat |img |vacb> In addition, the dumping process produces a bunch of output, of the form: <DataSectionObject|ImageSectionObject|SharedCacheMap> <hex number> <number> <file path> with no column header or other indication of what exactly these values refer to. (If I had to guess, maybe the hex value is the data offset within the image?) Looking at this format (without knowing for sure exactly what the numbers are referring to) would lead me to expect that the <number> and <hex number> fields from the output should correspond to the ones in the dumped filenames, and thus the file paths should have some correspondence to the dumped file data, if the values match up. Not necessarily being the contents of exact file to which the path corresponds, but being related in some way. But I'm not seeing the same hex value show up anywhere in the output and in ANY filename... Trying for a specific correspondence, I went looking through the dumped files, and was able to positively identify the Software registry hive. The associated filename was file.4.0x8697a2b8.vacb. Looking through the output for entries associated with this file identified the following two entries: DataSectionObject 0x89291f90 4 \Device\HarddiskVolume1\WINDOWS\system32\config\software SharedCacheMap 0x89291f90 4 \Device\HarddiskVolume1\WINDOWS\system32\config\software I'm probably just completely misinterpreting the output, but could somebody throw me a bone? Thanks much John

Cuckoo and Volatility

by Thorsten Sick

Hi List I am writing a Volatility plugin for Cuckoobox: https://github.com/Thorsten-Sick/cuckoo/tree/volatility That allows us to automate Malware analysis. Cuckoobox runs the malware and creates a memory snapshot. Volatility extracts the information, Cuckoobox afterwards generates nice reports from that. These are ready for statistics and automated processing. I hope to get the changes into the next Cuckoobox 0.7. But at the moment using Volatility 2.2 I had to duplicate some code from the Volatility plugins in Cuckoobox. I need data (python dict), not a text log. Instead of duplicating code I would love to have a method in the voaltility plugins that returns the data instead of some text log. I would code that and (if you want) re-create the render_text methods to also use the data from this method. * What do you think ? * Where to submit it for fast review and integration ? * Any other requirements ? * For which volatility version should I code (as far as I know you are about to release 2.3 soonish) Cheers Thorsten Sick -- Thorsten Sick, Research Avira Operations GmbH & Co.

Ideas and suggestions for user space memory forensics

by Edwin Smulders

Hi developers and enthusiasts, A while ago I introduced myself here, as I am doing a study into user space memory forensics. My goal is to develop a general method to extract information from user space, from any process. The past few months I have worked on some proof of concepts, and some basic experimentation. This has all been fairly easy, but I want to do something more complex. Today I am mailing you to ask for some ideas and suggestions. To give you an idea of what I have done so far (and the level I'm working on), here's a short list: - Extract register contents from the process kernel stack - Determine the exact locations of stack frames - Make a list of all process threads and access their stacks - Walk a list of pointers and do heuristic search on small structs, such as common networking structs (NOTE: All using a linux dump) All of this worked fairly well, and it was fun, but not exactly groundbreaking. I thought it would be best to ask the advice from professionals before I continue. The direction I would like to take is doing something more foolproof than a heuristic search, I would rather derive the location of structures using information in memory. One idea I had was to identify the whole stack trace (i.e. including function names) and use this to find struct locations. Since there is always the issue of missing symbols, I would somehow have to reintroduce these, and also figure out how dynamic symbols work. I am especially interested in common libraries with this approach, since something I can apply to libraries, I can apply to many processes. Another idea I had would be to use the source/headers of the application, maybe similar to the way volatility uses the symbols for the kernel. Now I don't really have a question about this, I am just looking for ideas. Please tell me if you think my ideas are good, or bad. If you read this and wonder why I don't do X instead of Y, please ask me. Feel free to mention any problems you see coming. I am really looking for a discussion here. The only requirements I have at this moment are that it stays roughly the same topic and it is academically relevant. That last part also means that if you know about somebody doing exactly this, do let me know, so I can do something else. If you know of any technical documentation or scientific research in the area, I'm also interested in that. The most relevant paper (in the whole topic of user space memory forensics) I have read so far is "Digging for Data Structures", Cozzie et al (thanks emdel for showing me that one). I permanently reside on IRC, Freenode/#volatility, if anyone cares to chat some more about the topic. Cheers, Edwin

Re: [Vol-dev] Breakpoints On Instruction calls

by A B

Tamas, Nir, Michael, Thank you all for the replies. I suspected something similar about Vmware not synching the vmem file too often. Michael, WinpMem seems to be a very good method (from the video), I deliberately didn't look into the source code yet, because I think I need to develop something similar, and would like to do so from scratch. We cannot use any existing code. I tried to avoid writing a driver since it complicated maintenance and release cycles, typically extending them, but if there is no easy way, perhaps that is the way to go. For my previous driver experience (and please correct me if I am wrong), this driver needs to interpret Windows memory management and open sections of memory and furnish the contents and contexts through IOCTLs to the user mode service for further analysis. A few quick questions : 1. This can be done completely agentless? Which means we need to insert nothing inside the VMs? Everything stays in the hyper-visor. 2. Have you guys tried constructing the call stack for such a break point? So when one hits a memory location and that is a function call, I would like to interpret the frames to get a call stack for the function call? (perhaps this is already mentioned in the video, and I didnt pay enough attention) Thanks amit On Sat, Jun 1, 2013 at 3:33 AM, Michael Cohen <scudette(a)gmail.com> wrote: > Hi ab, > You can use volatility tech preview with live systems by simply loading > the winpmem driver (using the -l option) and then pointing volatility at > the live memory (i.e. the \\.\pmem device).

Breakpoints On Instruction calls

by A B

All, This is my first post in this forum, and I am also very new to this website, so please excuse my ignorance. This is a fantastic project no doubt. Now, coming to my questions: 1. Is it possible to run volatility on a running 'live' VM's memory? That is, assuming that I have vmware work station running, can I use the live vmem file as input and get reliavble outputs? 2. If one is possible, then is it possible to generate a breakpoint or get a call back when a particular memory location is hit? I ask this because, assuming that an executable is loaded in certain pages inside the vmem, and I want to get notified when a particular function of that loaded executable is called, this wuld mean that when the virtual CPU executes the first instruction of that function I need a callback, is that possible? thanks in advance... -- - ab
