volatility [option] volatility -f [image] --profile=[profile] [plugin]

Configuration files are typically 'volatilityrc' in the current direc‐ tory or '~/.volatilityrc' in user's home directory, or at user speci‐ fied path, using the --conf-file option. An example of the file con‐ tents is shown below: [DEFAULT] PROFILE=Win7SP0x86 LOCATION=file:///tmp/myimage.img KDBG=0x82944c28 Other plugin flags may be utilized in this way, for example KPCR, DTB or PLUGINS. When exporting variables, simply prefix VOLATILITY_ before the flag name (e.g. VOLATILITY_KPCR). Otherwise, the flag name remains the same when adding it to the configuration file. If you have a path with a space or more in the name, spaces should be replaced with %20 instead (e.g. LOCATION=file:///tmp/my%20image.img).

Setting a timezone Timestamps extracted from memory can either be in system-local time, or in Universal Time Coordinates (UTC). If they're in UTC, Volatility can be instructed to display them in a time zone of the analyst's choosing. To choose a timezone, use one of the standard timezone names (such as America/Sao_Paulo, Europe/London, US/Eastern or most Olson timezones) with the --tz=TIMEZONE flag. Volatility attempts to use pytz if installed, otherwise it uses tzset. Please note that specifying a timezone will not affect how system-local times are displayed. If you identify a time that you know is UTC-based, please file it as an issue in the issue tracker. By default the _EPROCESS CreateTime and ExitTime timestamps are in UTC. Setting the DTB The DTB (Directory Table Base) is what Volatility uses to translate virtual addresses to physical addresses. By default, a kernel DTB is used (from the Idle/System process). If you want to use a different process's DTB when accessing data, supply the address to --dtb=ADDRESS. Setting the KDBG address (this is a Windows-only option) Volatility scans for the '_KDDEBUGGER_DATA64' structure using hard-coded signatures "KDBG" and a series of sanity checks. These signatures are not critical for the operating system to function properly, thus malware can overwrite them in attempt to throw off tools that do rely on the signature. Additionally, in some cases there may be more than one '_KDDEBUGGER_DATA64' (for example if you apply a major OS update and don't reboot), which can cause confusion and lead to incorrect process and module listings, among other problems. If you know the address add '_KDDEBUGGER_DATA64', you can specify it with --kdbg=ADDRESS and this override the automated scans. For more information, see the kdbgscan plugin. Setting the KPCR address (this is a Windows-only option) There is one KPCR (Kernel Processor Control Region) for each CPU on a system. Some Volatility plugins display per-processor information. Thus if you want to display data for a specific CPU, for example CPU 3 instead of CPU 1, you can pass the address of that CPU's KPCR with --kpcr=ADDRESS. To locate the KPCRs for all CPUs, see the kpcrscan plugin. Also note that starting in Volatility 2.2, many of the plugins such as idt and gdt automatically iterate through the list of KPCRs. Enabling write support Write support in Volatility should be used with caution. Therefore, to actually enable it, you must not only type --write on command-line but you must type a 'password' in response to a question that you'll be prompted with. In most cases you will not want to use write support since it can lead to corruption or modification of data in your memory dump. However, special cases exist that make this feature really interesting. For example, you could cleanse a live system of certain malware by writing to RAM over firewire, or you could break into a locked workstation by patching bytes in the winlogon DLLs. Specifying additional plugin directories Volatility's plugin architecture can load plugin files from multiple directories at once. In the Volatility source code, most plugins are located in volatility/plugins. However, there is another directory (volatility/contrib) which is reserved for contributions from third party developers, or weakly supported plugins that simply aren't enabled by default. To access these plugins you just type --plugins=contrib/plugins on command-line. It also enables you to create a separate directory of your own plugins that you can manage without having to add/remove/modify files in the core Volatility directories. Notes: On Debian systems, the contrib/plugins directory is at /usr/share/volatility/contrib/plugins. Subdirectories will also be traversed as long as there is an __init__.py file (which can be empty) within them. The parameter to --plugins can also be a zip file containing the plugins such as --plugins=myplugins.zip. Due to the way plugins are loaded, the external plugins directory or zip file must be specified before any plugin-specific arguments (including the name of the plugin). Example: $ volatility --plugins=contrib/plugins -f XPSP3x86.vmem example Choosing an output format By default, plugins use text renderers to standard output. If you want to redirect to a file, you can of course use the console's redirection (i.e. > out.txt) or you could use --output-file=out.txt. The reason you can also choose --output=FORMAT is for allowing plugins to also render output as HTML, JSON, SQL, or whatever you choose. However, there are no plugins with those alternate output formats pre-configured for use, so you'll need to add a function named render_html, render_json, render_sql, respectively to each plugin before using --output=HTML. Plugin specific options Many plugins accept arguments of their own, which are independent of the global options. To see the list of available options, type both the plugin name and -h/--help on command-line. $ volatility dlllist -h Debug mode If something isn't happening in Volatility the expected way, try to run the command with -d/--debug. This will enable the printing of debug messages to standard error. To more debug levels, as in using pdb debugger), add -d -d -d to command. Using Volatility as a library Although its possible to use Volatility as a library, (there are plans to support it better in the future). Currently, to import Volatility from a python script, the following example code can be used: $ python >>> import volatility.conf as conf >>> import volatility.registry as registry >>> registry.PluginImporter() >>> config = conf.ConfObject() >>> import volatility.commands as commands >>> import volatility.addrspace as addrspace >>> registry.register_global_options(config, commands.Command) >>> registry.register_global_options(config, addrspace.BaseAddressSpace) >>> config.parse_options() >>> config.PROFILE="WinXPSP2x86" >>> config.LOCATION = "file:///media/memory/private/image.dmp" >>> import volatility.plugins.taskmods as taskmods >>> p = taskmods.PSList(config) >>> for process in p.calculate(): ... print process

The Volatility Framework is a completely open collection of tools for the extraction of digital artifacts from volatile memory (RAM) samples. It is useful in forensics analysis. The extraction techniques are per‐ formed completely independent of the system being investigated but of‐ fer unprecedented visibility into the runtime state of the system. Currently, Volatility (version 2.6) supports several versions of the MS Windows, Linux and MAC OSX: • 32-bit Windows XP Service Pack 2 and 3 • 32-bit Windows Vista Service Pack 0, 1, 2 • 32-bit Windows 7 Service Pack 0, 1 • 32-bit Windows 8, 8.1, and 8.1 Update 1 • 32-bit Windows 10 • 32-bit Windows 2003 Server Service Pack 0, 1, 2 • 32-bit Windows 2008 Server Service Pack 1, 2 (there is no SP0) • 64-bit Windows XP Service Pack 1 and 2 (there is no SP0) • 64-bit Windows 2003 Server Service Pack 0, 1, 2 • 64-bit Windows Vista Service Pack 0, 1, 2 • 64-bit Windows 2008 Server Service Pack 1 and 2 (there is no SP0) • 64-bit Windows 2008 R2 Server Service Pack 0 and 1 • 64-bit Windows 7 Service Pack 0 and 1 • 64-bit Windows 8, 8.1, and 8.1 Update 1 • 64-bit Windows Server 2012 and 2012 R2 • 64-bit Windows 10 • 64-bit Windows Server 2016 • 32-bit Linux kernels 2.6.11 to 4.2.3 • 64-bit Linux kernels 2.6.11 to 4.2.3 • 32-bit 10.5.x Leopard (the only 64-bit 10.5 is Server, which isn't supported) • 32-bit 10.6.x Snow Leopard • 64-bit 10.6.x Snow Leopard • 32-bit 10.7.x Lion • 64-bit 10.7.x Lion • 64-bit 10.8.x Mountain Lion (there is no 32-bit version) • 64-bit 10.9.x Mavericks (there is no 32-bit version) • 64-bit 10.10.x Yosemite (there is no 32-bit version) • 64-bit 10.11.x El Capitan (there is no 32-bit version) • 64-bit 10.12.x Sierra (there is no 32-bit version) The memory formats supported are: • Raw linear sample (dd) • Hibernation file (from Windows 7 and earlier) • Crash dump file • VirtualBox ELF64 core dump • VMware saved state and snapshot files • EWF format (E01) • LiME format • Mach-O file format • QEMU virtual machine dumps • Firewire • HPAK (FDPro) The supported address spaces (RAM types) are: • AMD64PagedMemory - Standard AMD 64-bit address space. • ArmAddressSpace - Address space for ARM processors. • FileAddressSpace - This is a direct file AS. • HPAKAddressSpace - This AS supports the HPAK format. • IA32PagedMemory - Standard IA-32 paging address space. • IA32PagedMemoryPae - This class implements the IA-32 PAE pag‐ ing address space.

The supported plugin commands and profiles can be viewed if using the command '$ volatility --info'. Note that Linux and MAC OSX allowed plugins will have the 'linux_' and 'mac_' prefixes. Plugins without these prefixes were designed for MS Windows. Profiles are maps used by Volatility to understand the operational sys‐ tems. The allowed MS Windows profiles are provided by the Volatility. You must create your own profiles for Linux and MAC OSX. For this, on Debian systems, read the README.Debian file provided by volatility- tools package. On MS Windows, to determine the OS type, you can use: $ volatility -f imageinfo or $ volatility -f kdbgsca

On a GNU/Linux or OS X system, these variables can be set: • VOLATILITY_PROFILE - Specifies a profile to be used as de‐ fault, making unnecessary a '--profile' option. • VOLATILITY_LOCATION - Specifies the path of an image. So, the Volatility command will not need a file name via '-f' option. • VOLATILITY_KDBG - Specifies a KDBG address. See EXTRA PROCE‐ DURES to more details. Other plugin flags may be utilized in this way, for example KPCR, DTB or PLUGINS. When exporting variables, simply prefix VOLATILITY_ before the flag name (e.g. VOLATILITY_KPCR). Otherwise, the flag name remains the same when adding it to the configuration file. If you have a path with a space or more in the name, spaces should be replaced with %20 instead (e.g. LOCATION=file:///tmp/my%20image.img). Example: $ export VOLATILITY_PROFILE=Win7SP0x86 $ export VOLATILITY_LOCATION=file:///tmp/myimage.img $ export VOLATILITY_KDBG=0x82944c28
