I'm wondering if there is a plugin/command to extract commands that have been run in the past via RDP/telnet etc...I have taken a look at few things, but usually I would look in the csrss.exe process dump. However, we went to an overall memory dump recently and it makes it a little more difficult to parse through. Thanks for any input Jesse

hibernation files

by Matthew Donovan

On this mailing list there was some discussion about hibernation files with the first page (0x1000 bytes) zeroed out. The SVN version of hibinfo converts one of these "inactive" hibernation files into a raw dd-type image. But that seems to be all the support it currently has. As an experiment, we changed is_hiberfil() to always return True and ran the Volatility commands on an inactive hibernation file. They all appear to run successfully. So this leads to a few questions: 1) Was that just a fluke of the file we used that the Volatility commands worked? 2) Are there any plans to identify/support hibernation files with the first page zeroed out? 3) Can we assume that a file with the first 0x1000 bytes zeroed out is a hibernation file? 4) If the answer to (2) is 'no' and the answer to (3) is 'yes', where can we submit a patch? Thanks -matthew

hibinfo script

by Mark Morgan

I have a hiberfil.sys file from a windows xp sp3 machine and I am trying to convert it to dd using the hibinfo script in volatility. I keep getting an error half through the script as follows: $ python volatility hibinfo -f /c/Documents\ and\ Settings/Mark\ Morgan/My\ Doc uments/Hiberfil\ Test/hiberfil.sys -d /c/Documents\ and\ Settings/Mark\ Morgan/ My\ Documents/Hiberfil\ Test/hiber.dd Signature: SystemTime: Thu Jan 01 00:00:00 1970 Control registers flags CR0: 80010031 CR0[PAGING]: 1 CR3: 0afc0080 CR4: 000006f1 CR4[PSE]: 1 CR4[PAE]: 1 Traceback (most recent call last): File "volatility", line 219, in <module> main() File "volatility", line 212, in main modules[argv[1]].execute(argv[1], argv[2:]) File "c:\Volatility-1.3_Beta\vmodules.py", line 62, in execute self.cmd_execute(module, args) File "c:\Volatility-1.3_Beta\vmodules.py", line 1677, in hibinfo (major,minor,build) = hiberAS.get_version() File "c:\Volatility-1.3_Beta\forensics\win32\hiber_addrspace.py", line 452, in get_version addr_space = IA32PagedMemoryPae(self,self.CR3) NameError: global name 'IA32PagedMemoryPae' is not defined I am wondering if it is because this is a sp3 box???

Re: [Vol-users] hibinfo script

I'm sorry, that by far exceeds my knowledge about the hibernate stuff. I don't even have a suitable file for testing on stock. Could someone else please look into this?

Help with ModDump

by Mark Morgan

I am using WIN XP SP 2, python 2.6.2 and the 1.3 beta of volatility. I can get all the scripts to work just fine except those that require a dump. I am trying to dump the mods out of memory using the following syntax: python volatility moddump -f /c/memory.img > /f/dumps I have also tried with the backslash and forward slash but I either get the error: "File exists" or "Access Denied" Any help would be appreciated.

Unexplained Errors

by Robert Miller

Hello Everyone, I have been dumping memory on a few systems and when I go to process the memory images I get different errors, some of these I think I've found the answers but not sure on others. Here are the errors I have seen: procdump: ======= Memory Not Accessible: Virtual Address: 0x4ad50000 File Offset: 0x50000 Size: 0x1000 pslist: ==== volatility_v1.3/forensics/win32/crashdump.py:31: DeprecationWarning: the sha module is deprecated; use the hashlib module instead import sha *** Unable to load module malfind: No module named pydasm *** Unable to load module malfind: No module named pydasm datetime: ====== /volatility_v1.3/forensics/win32/crashdump.py:31: DeprecationWarning: the sha module is deprecated; use the hashlib module instead import sha *** Unable to load module malfind: No module named pydasm *** Unable to load module malfind: No module named pydasm I believe the DeprecationWarning is due to the version of Python, which is 2.6.2 The malfind module, not sure why I downloaded the module and have not looked into it, however there should not be an issue, but there is. Any Advice? Thanks, Robert

decompression of hyberfil.sys

by Michael Felber , Steufa Chemnitz, IT-Forensik

Hello all, I have posted this twice because the decompression issue should be moved to vol-dev as Aaron suggested. yesterday Andreas did provide a hiberfil.sys for decompression testing. Thanks a lot again. I have processed it twice with X-Ways-Forensics 15.3 SR3 and Volatility (SVN-release). The good news: Both result files are identical. The bad news: I dont have any clue why the decompression of my case relevant hiberfil.sys did not properly work with volatility but did with XWF. If anyone other needs a hiberfil.sys decompressed with XWF for testing, do not hesitate to ask me. We have the most recent releases here. (I am back on the 29th of July) I did compare the vol and the XWF-version of my case files but I cant interpret or explain the differences. What should I look for?
