I built LiME from the tarball on the project site (not latest svn) and was able to dump memory successfully (type=lime). After many trials and tribulations I was able to get the Volatility profile built for CentOS 5.3x64 (had to remove pmem from the Makefile). I put the profile in the correct directory, and vol.py --info lists it as expected, however when I try to use the profile with the memory image I get an error. chort@hydra:~/code/profiles-volatility/CentOS_5.3_x64$ vol.py --profile=LinuxCentOS_5_3x64 -f /fun/ir/geriatrix.lime linux_lsmod Volatile Systems Volatility Framework 2.3_alpha WARNING : volatility.obj : Overlay structure cpuinfo_x86 not present in vtypes No suitable address space mapping found Tried to open image as: MachOAddressSpace: mac: need base LimeAddressSpace: lime: need base WindowsHiberFileSpace32: No base Address Space WindowsCrashDumpSpace64: No base Address Space HPAKAddressSpace: No base Address Space VirtualBoxCoreDumpElf64: No base Address Space VMWareSnapshotFile: No base Address Space WindowsCrashDumpSpace32: No base Address Space JKIA32PagedMemoryPae: No base Address Space AMD64PagedMemory: No base Address Space JKIA32PagedMemory: No base Address Space IA32PagedMemoryPae: Module disabled IA32PagedMemory: Module disabled MachOAddressSpace: MachO Header signature invalid MachOAddressSpace: MachO Header signature invalid LimeAddressSpace: Invalid Lime header signature WindowsHiberFileSpace32: PO_MEMORY_IMAGE is not available in profile WindowsCrashDumpSpace64: Header signature invalid HPAKAddressSpace: Invalid magic found VirtualBoxCoreDumpElf64: ELF64 Header signature invalid VMWareSnapshotFile: Invalid VMware signature: 0xf000ff53 WindowsCrashDumpSpace32: Header signature invalid JKIA32PagedMemoryPae: Incompatible profile LinuxCentOS_5_3x64 selected AMD64PagedMemory: Failed valid Address Space check JKIA32PagedMemory: Incompatible profile LinuxCentOS_5_3x64 selected IA32PagedMemoryPae: Module disabled IA32PagedMemory: Module disabled FileAddressSpace: Must be first Address Space ArmAddressSpace: Incompatible profile LinuxCentOS_5_3x64 selected On a hunch I checked the directory I built the profile in (copied headers & source from the target system): chort@hydra:~/code/profiles-volatility/CentOS_5.3_x64$ grep cpuinfo * System.map-2.6.18-128.el5:ffffffff8006f328 t show_cpuinfo System.map-2.6.18-128.el5:ffffffff80103251 t cpuinfo_open System.map-2.6.18-128.el5:ffffffff8020eadb t show_cpuinfo_max_freq System.map-2.6.18-128.el5:ffffffff8020eafa t show_cpuinfo_min_freq System.map-2.6.18-128.el5:ffffffff8020f759 t show_cpuinfo_cur_freq System.map-2.6.18-128.el5:ffffffff802f0bc0 D cpuinfo_op System.map-2.6.18-128.el5:ffffffff80308420 d proc_cpuinfo_operations System.map-2.6.18-128.el5:ffffffff803319a0 d cpuinfo_cur_freq System.map-2.6.18-128.el5:ffffffff80331b20 d cpuinfo_min_freq System.map-2.6.18-128.el5:ffffffff80331b60 d cpuinfo_max_freq Platform running Volatility (2.3_alpha, latest from svn): Linux hydra 3.2.0-35-generic #55-Ubuntu SMP Wed Dec 5 17:42:16 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux Source of memory image: Linux geriatrix.smtps.net 2.6.18-128.el5 #1 SMP Wed Jan 21 10:41:14 EST 2009 x86_64 x86_64 x86_64 GNU/Linux What am I missing? -- chort

Any input appreciated... -=[ Steve ]=-

FW: Memory-mapped file and shared pages

by Joshua Davies

Hi list, I'm currently doing some memory analysis, and I'm using Notepad on Windows 7 x64 as an example. My question is this: is there any way to link a _FILE_OBJECT back to the process that generated it, without a valid handle, or an entry in the VAD tree. This article discusses it: http://computer.forensikblog.de/en/2009/04/linking-file-objects-to-processe… - however, this approach only works if there is a valid handle for the open file. Here's an example: I open notepad, and open a simple text file that contains "This is the contents of the file". Performing a scan over the memory dump reveals this data in two locations: 1 - 0x1448f000 - This is the contents of the file found through the _FILE_OBJECT->SectionObjectPointers->DataSectionObject. This points to a control area, and through that I can locate the Subsection-BasePTE which shows that the page is in transition and has a PFN of 0x1448f. So this allows me to the find the data through the _FILE_OBJECT 2 - 0x39d336b0 - This address is currently part of Notepad's private heap, which is where the data has been mapped into. So examining the two pages through WinDbg gives me this information: lkd> !pfn 1448f PFN 0001448F at address FFFFFA80003CDAD0 flink 00015B8F blink / share count 00013ED5 pteaddress FFFFF8A0008AD010 reference count 0000 used entry count 0000 Cached color 0 Priority 5 restore pte FA800325553004C0 containing page 00ABBA Standby P Shared lkd> !pte FFFFF8A0008AD010 1 VA fffff8a0008ad010PXE at FFFFF8A0008AD010 PPE at FFFFF8A0008AD010 PDE at FFFFF8A0008AD010 PTE at FFFFF8A0008AD010contains 000000001448F8C0not valid Transition: 1448f Protect: 6 - ReadWriteExecute As can be seen, the page containing the original data is shared, is on the standby list, and points to a prototype PTE. lkd> !pfn 39d33 PFN 00039D33 at address FFFFFA8000AD7990 flink 00039D88 blink / share count 00039D1E pteaddress FFFFF6800001CAC8 reference count 0000 used entry count 0000 Cached color 0 Priority 3 restore pte 1635500000080 containing page 0274B8 Standby lkd> !pte FFFFF6800001CAC8 1 VA fffff6800001cac8PXE at FFFFF6800001CAC8 PPE at FFFFF6800001CAC8 PDE at FFFFF6800001CAC8 PTE at FFFFF6800001CAC8contains 0000000000000000not valid The PTE within Notepad's heap is marked as not valid, but also shows that the page is on the standby list. As the page located through the FILE_OBJECT is marked as shared, and points to a prototype PTE, is there anyway of locating this prototype PTE, and using it to track back to Notepad? So for instance, would it be possible to locate the PPTE by searching memory for the 'MmSt' tag, and then parse the PPTE to gain any information. Or does the PPTE not track backwards in that way? Essentially, if the page containing the data found through the _FILE_OBJECT is shared, what is it shared with, and is it possible to track this information, using either the PFN database, prototype PTE entries, or something else I haven't thought of. Any input or advice would be appreciated. Thanks Josh.

dumping registry hive(s) from memory image

by Roger

I've been trying to get/dump a copy of a certain registry hive from the memory. Managed to list down their offsets using hivelist plugin but unable to find ways of dumping them to files. My intention is to load it to other tools such as regripper as input/target registry files. Has any one found a way of doing it? Thank you very much in advance. Kind regards, Roger

Re: [Vol-users] Difficulty creating CentOS profiles

by Andrew Case

So was the fix just to switch to lime format or did you also need the patch? This will help us keep better documentation for future bug reports. Also, is there a reason you need the raw sample? If you are looking for a sample without any metadata, the best version would be 'padded' since it zero fills the offsets between RAM sections, but note that you can get a HUGE file, especially on 64 bit systems. The raw version of LiME simply concatantes regions together (does not pad), which make offsets found from virtual address translation off. This is why Volatility (and other tools) cannot process most raw Lime dumps.

It only requires two small changes to the existing code.

Difficulty creating CentOS profiles

by Torres, Geoff (Global Cyber Security)

Hi, I've been unable to create a working Linux profile for any version of CentOS. It compiles fine but gives a 'No suitable address space mapping found' error when ran against the memory image. I've been successful creating various Debian and Ubuntu profiles, but CentOS has yet to work. I'm sure it's something simple but I can't figure it out. I'm certain that I'm matching kernel versions correctly and that the build process is the same as I use for the Ubuntu versions. I've attached the details of my most recent attempt. It's a vanilla CentOS 5.10 install on VmWare. The memory image is available (250Mb zip) if necessary. Any ideas? None of the solutions I found in Google seem to address my issue. Thanks, Geoff BTW - I'm not a kernel programmer so please be detailed if there's something you'd like me to try.
