The Volatility Framework 2.5 Windows Core Command Reference
メモリフォレンジックツールのVolatility Frameworkコマンドリファレンスの日本語訳です。Windows Core、Windows Malware、Windows GUIという順番で翻訳する予定です。(気力が続けば)
Image Identification
imageinfo
For a high level summary of the memory sample you're analyzing, use the imageinfo command. Most often this command is used to identify the operating system, service pack, and hardware architecture (32 or 64 bit), but it also contains other useful information such as the DTB address and time the sample was collected.
imageinfoコマンドで解析するメモリサンプルの概要が分かります。主にOSの種類、サービスパックの有無、ハードウェアアーキテクチャ(32/64bit)を識別するために利用されますが、DTBアドレスといった有益な情報を知ることもできます。

The imageinfo output tells you the suggested profile that you should pass as the parameter to --profile=PROFILE when using other plugins. There may be more than one profile suggestion if profiles are closely related. It also prints the address of the KDBG (short for _KDDEBUGGER_DATA64) structure that will be used by plugins like pslist and modules to find the process and module list heads, respectively. In some cases, especially larger memory samples, there may be multiple KDBG structures. Similarly, if there are multiple processors, you'll see the KPCR address and CPU number for each one.
imageinfoは、別のプラグインを実行する際に--profile=PROFILEオプションで指定すべきプロファイルを示唆してくれます。関連する複数のプロファイルが示される場合もあります。pslistやプロセスとモジュールリストを探索するプラグインで利用されるKDBG構造体(_KDDEBUGGER_DATA64)のアドレスも表示します。特に大きなメモリサンプルでは、複数のKDBG構造体のアドレスが示されるかもしれません。同じように複数のプロセッサを持ったシステムの場合、それぞれにKPCRアドレスとCPU番号が表示されます。
Plugins automatically scan for the KPCR and KDBG values when they need them. However, you can specify the values directly for any plugin by providing --kpcr=ADDRESS or --kdbg=ADDRESS. By supplying the profile and KDBG (or failing that KPCR) to other Volatility commands, you'll get the most accurate and fastest results possible.
volatilityのプラグインは必要に応じて自動的にKPCRとKDBGの値をスキャンしますが、--kpcr=ADDRESSと--kgbg=ADDRESSというパラメータで明示的に指定することもできます。プロファイルとKDBGをコマンドに与えることによって、最も正確な結果を高速に得ることができます。
Note: The imageinfo plugin will not work on hibernation files unless the correct profile is given in advance. This is because important structure definitions vary between different operating systems.
Note: ハイバネーションファイルに対しては正しいプロファイルを指定しないとimageinfoは機能しません。これはOS間で重要な構造体の定義が異なるためです。
kdbgscan
As opposed to imageinfo which simply provides profile suggestions, kdbgscan is designed to positively identify the correct profile and the correct KDBG address (if there happen to be multiple). This plugin scans for the KDBGHeader signatures linked to Volatility profiles and applies sanity checks to reduce false positives. The verbosity of the output and number of sanity checks that can be performed depends on whether Volatility can find a DTB, so if you already know the correct profile (or if you have a profile suggestion from imageinfo), then make sure you use it.
単純にプロファイルを示唆するimageinfoとは違い、kdbgscanは正確なプロファイルとKDBGアドレス(複数存在すれば)を識別するようにデザインされています。このプラグインは、プロファイルに対応したKDBGHeaderシグニチャをスキャンし、誤検知を低下させるためのチェックを行います。出力の詳細さと実行可能なチェック数は、VolatilityがDTBを見つけられるかによります。そのため、すでに正確なプロファイルを知っている場合(またはimageinfoで示唆された場合)、それを利用するべきです。
Here's an example scenario of when this plugin can be useful. You have a memory sample that you believe to be Windows 2003 SP2 x64, but pslist doesn't show any processes. The pslist plugin relies on finding the process list head which is pointed to by KDBG. However, the plugin takes the first KDBG found in the memory sample, which is not always the best one. You may run into this problem if a KDBG with an invalid PsActiveProcessHead pointer is found earlier in a sample (i.e. at a lower physical offset) than the valid KDBG.
このプラグインが有用なのは、こんな場合です。Windows 2003 SP2 x64のものであると考えているイメージサンプルがあるが、pslistコマンドはプロセスを表示してくれません。pslistはKDBGから示されるプロセスリストヘッドを利用していますが、pslistは必ずしもふさわしいとはいえないメモリ内で初めに見つかったKDBGを利用します。不正なPsActiveProcessHeadポインタを持つKDBGが、(低い物理アドレスに位置しているなどの理由で)正しいKDBGより先に見つかった場合にこういった問題に遭遇するかもしれません。
Notice below how kdbgscan picks up two KDBG structures: an invalid one (with 0 processes and 0 modules) is found first at 0xf80001172cb0 and a valid one (with 37 processes and 116 modules) is found next at 0xf80001175cf0. In order to "fix" pslist for this sample, you would simply need to supply the --kdbg=0xf80001175cf0 to the plist plugin.
下記の例では、kdbgscanが2つのKDBGを見つけていることに注目してください。正しくない方が先に0xf80001172cb0で見つかっていて、(37プロセスと116モジュールに対する)正しい方が後から0xf80001175cf0で見つかっています。このサンプルでは、pslistプラグインに対して--kdbg=0xf80001175cf0と指定すれば、pslistは正しく動作します。

kpcrscan
Use this command to scan for potential KPCR structures by checking for the self-referencing members as described by Finding Object Roots in Vista. On a multi-core system, each processor has its own KPCR. Therefore, you'll see details for each processor, including IDT and GDT address; current, idle, and next threads; CPU number, vendor & speed; and CR3 value.
kpcrscanコマンドで、"Finding Object Roots in Vista"で説明されているように、自己参照をチェックすることにより、KPCR構造体を探すことができます。複数のCPUコアを持つシステムでは、それぞれのプロセッサがKPCRを持ちます。IDTとGDTアドレスを含む、現在／アイドル／次のスレッド、CPU番号、ベンダー、スピード、CR3の値など、それぞれのプロセッサの詳細を確認できます。

If the KdVersionBlock is not null, then it may be possible to find the machine's KDBG address via the KPCR. In fact, the backup method of finding KDBG used by plugins such as pslist is to leverage kpcrscan and then call the KPCR.get_kdbg() API function.
KdVersionBlockがnullではない場合、KPCRからKDBGを見つけることができるかもしれません。pslistなどのプラグインは、KDBGを見つけるための副次的な方法として、kpcrscanを使い、KPCR.get_kdbg() APIを利用しています。
Processes and DLLs
pslist
To list the processes of a system, use the pslist command. This walks the doubly-linked list pointed to by PsActiveProcessHead and shows the offset, process name, process ID, the parent process ID, number of threads, number of handles, and date/time when the process started and exited. As of 2.1 it also shows the Session ID and if the process is a Wow64 process (it uses a 32 bit address space on a 64 bit kernel).
pslistコマンドでプロセスを列挙します。PsActiveProcessHeadで示されるダブルリンクリストを辿って、オフセット、プロセス名、プロセスID、親プロセスID、スレッド数、ハンドル数、開始・終了時刻を表示します。バージョン2.1から、セッションID、WOW64プロセスかどうかも表示します(WOW64プロセスは、64bitシステム上で32bitアドレス空間を使用します)。
This plugin does not detect hidden or unlinked processes (but psscan can do that).
このプラグインでは、隠されたプロセスやリンクリストをはずされたプロセスは認識できません。(psscanは可能)
If you see processes with 0 threads, 0 handles, and/or a non-empty exit time, the process may not actually still be active. For more information, see The Missing Active in PsActiveProcessHead. Below, you'll notice regsvr32.exe has terminated even though its still in the "active" list.
スレッド数0、ハンドル数0で、終了時刻が表示される/されない場合、もうアクティブなプロセスではないかもしれません。詳しくは、"The Missing Active in PsActiveProcessHead"を参照。以下の例では、regsvr32.exeがアクティブリストに挙がっていても、すでに終了していることがわかります。
Also note the two processes System and smss.exe will not have a Session ID, because System starts before sessions are established and smss.exe is the session manager itself.
Sysemはセッション確立前に開始し、smss.exeはセッションマネージャそのものであるため、Systemとsmss.exeの2つのプロセスはセッションIDを持っていません。

By default, pslist shows virtual offsets for the EPROCESS but the physical offset can be obtained with the -P switch:
デフォルトでは、pslistはEPROCESSの仮想オフセットを表示しますが、-Pオプションによって物理オフセットを表示させることができます。

pstree
To view the process listing in tree form, use the pstree command. This enumerates processes using the same technique as pslist, so it will also not show hidden or unlinked processes. Child process are indicated using indention and periods.
pstreeコマンドは、ツリー形式のプロセスリストを表示します。pslistと同じ仕組みでプロセスを列挙するため、隠されたプロセスやリンクが外されたプロセスは表示されません。子プロセスは、インデントとピリオドで示されます。

psscan
To enumerate processes using pool tag scanning (POOL_HEADER), use the psscan command. This can find processes that previously terminated (inactive) and processes that have been hidden or unlinked by a rootkit. The downside is that rootkits can still hide by overwriting the pool tag values (though not commonly seen in the wild).
psscanコマンドは、プールタグ(POOL_HEADER)をスキャンすることによりプロセスを列挙する。既に停止した(アクティブではない)プロセス、rootkitによって隠されたプロセスやリンクを外されたプロセスも見つけ出すことができる。rootkitはプールタグを上書きすることもできることは問題です(現実にはあまり見られません)。

If a process has previously terminated, the Time exited field will show the exit time. If you want to investigate a hidden process (such as displaying its DLLs), then you'll need physical offset of the _EPROCESS object, which is shown in the far left column. Almost all process-related plugins take a --OFFSET parameter so that you can work with hidden processes.
プロセスが既に終了している場合、Time exitedフィールドが終了時刻を表します。(DLLのような)隠されたプロセスを調査したいなら、左の列に表示されているEPROCESSオブジェクトの物理オフセットが必要です。隠されたプロセスを調査するために、ほとんどのプロセス関連のプラグインには--OFFSETパラメータを指定することができます。
psdispscan
This plugin is similar to psscan, except it enumerates processes by scanning for DISPATCHER_HEADER instead of pool tags. This gives you an alternate way to carve _EPROCESS objects in the event an attacker tried to hide by altering pool tags. This plugin is not well maintained and only supports XP x86. To use it, you must type --plugins=contrib/plugins on command-line.
このプラグインはpsscanと似ていますが、プールタグではなくDISPATCHER_HEADERをスキャンすることによってプロセスを列挙します。攻撃者がプールタグを変更することによって隠蔽するような場合に、EPROCESSを調査する別のやり方となります。このプラグインはあまりメンテナンスされておらず、XP x86のみサポートされています。このプラグインを使用するためには、--plugins=contrib/pluginsというオプションを指定する必要があります。
dlllist
To display a process's loaded DLLs, use the dlllist command. It walks the doubly-linked list of _LDR_DATA_TABLE_ENTRY structures which is pointed to by the PEB's InLoadOrderModuleList. DLLs are automatically added to this list when a process calls LoadLibrary (or some derivative such as LdrLoadDll) and they aren't removed until FreeLibrary is called and the reference count reaches zero. The load count column tells you if a DLL was statically loaded (i.e. as a result of being in the exe or another DLL's import table) or dynamically loaded.
dlllistコマンドで、プロセスがロードしたDLLを表示することができる。PEBのInLoadOrderModuleListで示される_LDR_DATA_TABLE_ENTRY構造体のダブルリンクリストをたどっていく。プロセスがLoadLibraryをコールした際に(またはLdrLoadDllなどの派生によって)このリストに追加され、FreeLibraryが呼び出されて参照数が0になるまで削除されない。load count列は静的にロード(exeもしくは別のDLLのインポートテーブルに登録されていることにより)されたか動的にロードされたかを示す。

To display the DLLs for a specific process instead of all processes, use the -p or --pid filter as shown below. Also, in the following output, notice we're analyzing a Wow64 process. Wow64 processes have a limited list of DLLs in the PEB lists, but that doesn't mean they're the only DLLs loaded in the process address space. Thus Volatility will remind you to use the ldrmodules instead for these processes.
全プロセスではなく、特定のプロセスのDLLを表示する場合、下の例のように-pか--pidフィルタを指定します。この例では、Wow64プロセスを解析しています。Wow64プロセスは、PEBリストに限られたDLLのリストしか持っていませんが、それらだけがプロセスのアドレス空間にロードされたDLLではありません。そうしたプロセスのために、ldrmodulesを代わりに利用することができます。

To display the DLLs for a process that is hidden or unlinked by a rootkit, first use the psscan to get the physical offset of the EPROCESS object and supply it with --offset=OFFSET. The plugin will "bounce back" and determine the virtual address of the EPROCESS and then acquire an address space in order to access the PEB.
ルートキットによって隠蔽されたりリンクを外されたDLLを表示するためには、まずpsscanでEPROCESSの物理オフセットを取得して、--offset=OFFSETオプションで指定してください。プラグインは、"bounce back"して、EPROCESSの仮想アドレスを決定し、PEBにアクセスするためにアドレス空間を取得します。

dlldump
To extract a DLL from a process's memory space and dump it to disk for analysis, use the dlldump command. The syntax is nearly the same as what we've shown for dlllist above. You can:
dlldumpコマンドで、解析のためにプロセスのメモリ空間からDLLをディスクにダンプすることができます。指定の仕方は、上のdlllistの指定と同じです。以下の指定が可能です。
- Dump all DLLs from all processes
-
Dump all DLLs from a specific process (with --pid=PID)
-
Dump all DLLs from a hidden/unlinked process (with --offset=OFFSET)
-
Dump a PE from anywhere in process memory (with --base=BASEADDR), this option is useful for extracting hidden DLLs
-
Dump one or more DLLs that match a regular expression (--regex=REGEX), case sensitive or not (--ignore-case)
-
全プロセスから全DLLをダンプする
-
指定したプロセスの全DLLをダンプする(--pid=PID)
-
隠蔽やリンクを外されたプロセスからすべてのDLLをダンプする(--offset=OFFSET)
-
プロセスメモリのどこかからPE形式でダンプする(--base=BASEADDR)。これは隠されたDLLを取得するのに便利です。
-
正規表現にマッチした(複数の)DLLをダンプする(--regex=REGEX)。大／小文字を区別しない(--ignore-case)
To specify an output directory, use --dump-dir=DIR or -d DIR.
--dump-dir=DIRまたは-d DIRオプションで、出力ディレクトリを指定します。
$ python vol.py -f ~/Desktop/win7_trial_64bit.raw --profile=Win7SP0x64 dlldump -D dlls/

If the extraction fails, as it did for a few DLLs above, it probably means that some of the memory pages in that DLL were not memory resident (due to paging). In particular, this is a problem if the first page containing the PE header and thus the PE section mappings is not available. In these cases you can still extract the memory segment using the vaddump command, but you'll need to manually rebuild the PE header and fixup the sections (if you plan on analyzing in IDA Pro) as described in Recovering CoreFlood Binaries with Volatility.
上のいくつかのDLLのように抽出が失敗した場合、DLLの一部のメモリページが物理メモリ上にないのかもしれません(ページングによって)。特にPEヘッダの頭のページがなくてPEセクションマッピングが取得できない場合に問題となります。このような場合でも、vaddumpコマンドではメモリセグメントを抽出できますが、(IDA Proで解析しようとしているなら)”Recovering CoreFlood Binaries with Volatility”で解説しているようにPEヘッダを再構築してセクションを修復する必要があります。
To dump a PE file that doesn't exist in the DLLs list (for example, due to code injection or malicious unlinking), just specify the base address of the PE in process memory:
(コードインジェクションや悪意によってリンクを外されているような場合など)DLLリストにないPEファイルをダンプするには、プロセスメモリ中のPEのベースアドレスを指定します。
$ python vol.py --profile=Win7SP0x86 -f win7.dmp dlldump --pid=492 -D out --base=0x00680000
You can also specify an EPROCESS offset if the DLL you want is in a hidden process:
隠蔽されたプロセス内のDLLをダンプしたい場合、EPROCESSのオフセットを指定することもできます。
$ python vol.py --profile=Win7SP0x86 -f win7.dmp dlldump -o 0x3e3f64e8 -D out --base=0x00680000
handles
To display the open handles in a process, use the handles command. This applies to files, registry keys, mutexes, named pipes, events, window stations, desktops, threads, and all other types of securable executive objects. As of 2.1, the output includes handle value and granted access for each object.
handlesコマンドでプロセスがオープンしているハンドルを表示できます。ファイル、レジストリキー、ミューテックス、名前付きパイプ、イベント、ウィンドウステーション、デスクトップ、スレッド、他のすべてのSecurable executive objectsに適用されます。バージョン2.1から、ハンドルの値と許されるアクセスがそれぞれのオブジェクトに表示されるようになりました。

You can display handles for a particular process by specifying --pid=PID or the physical offset of an EPROCESS structure (--physical-offset=OFFSET). You can also filter by object type using -t or --object-type=OBJECTTYPE. For example to only display handles to process objects for pid 600, do the following:
--pid=PIDもしくはEPROCESS構造体の物理アドレスを--physical-offset=OFFSETというオプションで指定することにより、特定のプロセスのハンドルのみを表示させることができます。-tもしくは--object-type=OBJECTTYPEオプションで、オブジェクトをフィルタすることができます。pid 600(ママ)のプロセスのハンドルのみを表示したい場合は、次のようにします。

cmdscan
The cmdscan plugin searches the memory of csrss.exe on XP/2003/Vista/2008 and conhost.exe on Windows 7 for commands that attackers entered through a console shell (cmd.exe). This is one of the most powerful commands you can use to gain visibility into an attackers actions on a victim system, whether they opened cmd.exe through an RDP session or proxied input/output to a command shell from a networked backdoor.
cmdscanは、XP/2003/Vista/2008ではcsrss.exe、Windows 7ではconhost.exeのメモリから、攻撃者がコンソールシェル(cmd.exe)で入力したコマンドを探索します。これは被害を受けたシステムで攻撃者の行動について可視化を行うための最も強力なコマンドのひとつです。攻撃者がcmd.exeを使用した場合、RDPセッション経由の場合、インプットとアウトプットのプロキシを行うバックドアによってネットワーク経由でコマンドシェルを使った場合でも有効です。
This plugin finds structures known as COMMAND_HISTORY by looking for a known constant value (MaxHistory) and then applying sanity checks. It is important to note that the MaxHistory value can be changed by right clicking in the top left of a cmd.exe window and going to Properties. The value can also be changed for all consoles opened by a given user by modifying the registry key HKCU\Console\HistoryBufferSize. The default is 50 on Windows systems, meaning the most recent 50 commands are saved. You can tweak it if needed by using the --max_history=NUMBER parameter.
このプラグインは、既に知られている固定値(MaxHistory)から、COMMAND_HISTORYと呼ばれる構造体を見つけ、正常かどうかチェックします。cmd.exeのウィンドウの上部バーをライトクリックすることによってプロパティを変更すると、MaxHistoryの値が変わることは重要です。レジストリキーHKCU\Console\HistoryBufferSizeを変更することによってユーザのすべてのコンソールのMaxHistoryの値が変更されることもあります。
デフォルトでは50となっており、直近の50コマンドが記録されます。必要があれば、--max_history=NUMBERオプションで、調整することができます。
The structures used by this plugin are not public (i.e. Microsoft does not produce PDBs for them), thus they're not available in WinDBG or any other forensic framework. They were reverse engineered by Michael Ligh from the conhost.exe and winsrv.dll binaries.
このプラグインが利用している構造体は公式のものではありません(マイクロソフトは、PDBsの構造などを公開していません)ので、WinDBGやその他のフォレンジックフレームワークでは利用できません。Michael Lighがconhost.exeとwinsrv.dllのバイナリからリバースエンジニアリングしたものです。
In addition to the commands entered into a shell, this plugin shows:
シェルを調査するだけではなく、以下の情報を表示します。
- The name of the console host process (csrss.exe or conhost.exe)
-
The name of the application using the console (whatever process is using cmd.exe)
-

-
The application process handle
-
コンソールホストプロセスの名称(csrss.exeかconhost.exe)
-
コンソールを使っているアプリケーションの名称(cmd.exeを使っているどんなプロセスでも)
-

-

Due to the scanning technique this plugin uses, it has the capability to find commands from both active and closed consoles.

consoles
Similar to cmdscan the consoles plugin finds commands that attackers typed into cmd.exe or executed via backdoors. However, instead of scanning for COMMAND_HISTORY, this plugin scans for CONSOLE_INFORMATION. The major advantage to this plugin is it not only prints the commands attackers typed, but it collects the entire screen buffer (input and output). For instance, instead of just seeing "dir", you'll see exactly what the attacker saw, including all files and directories listed by the "dir" command.
cmdscanと同様に、comsolesプラグインは、攻撃者がcmd.exeにタイプしたかバックドア経由で実行したコマンドを探しだします。COMMAND_HISTORYをスキャンするのではなく、このプラグインでは、CONSOLE_INFORMATIONをスキャンします。攻撃者がタイプしたコマンドだけではなく、スクリーンバッファ全体(インプットとアウトプット)を取得できるところが優れています。例えば、単に"dir"と表示されるだけではなく、dirコマンドが表示したファイルとディレクトリのリストを含む、攻撃者が見たままを正確に表示することができます。
Additionally, this plugin prints the following:
更に、このプラグインでは以下の表示を行います。
- The original console window title and current console window title
-
The name and pid of attached processes (walks a LIST_ENTRY to enumerate all of them if more than one)
-
Any aliases associated with the commands executed. For example, attackers can register an alias such that typing "hello" actually executes "cd system"
-
The screen coordinates of the cmd.exe console
-
オリジナルのコンソールウィンドウタイトルと現在のウィンドウタイトル
-
アタッチされたプロセスの名前とpid(LIST_ENTRYをたどって列挙します)
-
実行されたコマンドに結び付けられたエイリアス。例えば、攻撃者は"hello"とタイプすると、"cd system"が実際には実行されるようにエイリアスと登録することができる

Here's an example of the consoles command. Below, you'll notice something quite funny. The forensic investigator seems to have lost his mind and cannot find the dd.exe tool for dumping memory. Nearly 20 typos later, he finds the tool and uses it.
これはconsolesコマンドの例です。下を見ると、おかしなことに気づくでしょう。フォレンジック調査者は、正気を失ったようで、メモリをダンプするためのdd.exeツールが見つけられません。20回近くの入力ミスのあと、ツールを見つけて実行しました。

privs
This plugin shows you which process privileges are present, enabled, and/or enabled by default. You can pass it the --silent flag to only show privileges that a process explicitly enabled (i.e. that were were not enabled by default but are currently enabled). The --regex=REGEX parameter can be used to filter for specific privilege names.
このプラグインは、どんなプロセス特権がPresent、有効化、デフォルトで有効化／無効化であるかを表示する。--silentオプションを指定することで、明示的に有効化されている特権のみを表示させることができる(デフォルトでは無効化されているが、現在有効かされているものなど)。--regex=REGEXオプションで、特定の特権のみをフィルタして表示させることができる。

envars
To display a process's environment variables, use the envars plugin. Typically this will show the number of CPUs installed and the hardware architecture (though the kdbgscan output is a much more reliable source), the process's current directory, temporary directory, session name, computer name, user name, and various other interesting artifacts.
envarsプラグインで、プロセスの環境変数を表示させることができる。典型的には、CPU数とハードウェアアーキテクチャ(kdbgscanの出力は、はるかに信頼できるが)、プロセスのカレントディレクトリ、テンポラリディレクトリ、セッション名、コンピュータ名、ユーザ名、様々な役に立つ情報などを表示する。

verinfo
To display the version information embedded in PE files, use the verinfo command. Not all PE files have version information, and many malware authors forge it to include false data, but nonetheless this command can be very helpful with identifying binaries and for making correlations with other files.
verinfoで、PEファイルに埋め込まれているバージョン情報を出力できる。すべてのPEファイルがバージョン情報を持っているわけではないし、多くのマルウェアの作者は誤った情報で偽装を行うが、バイナリを識別し別のファイルとの関連を調べるのに役に立つコマンドである。
This plugin only supports printing version information from process executables and DLLs, but later will be expanded to include kernel modules. If you want to filter by module name, use the --regex=REGEX and/or --ignore-case options.
このプラグインは、プロセスの実行ファイルとDLLのバージョン情報しかサポートしないが、カーネルモジュールまでサポート範囲が広がるだろう。モジュール名でフィルタをしたければ、--regex=REGEXと必要に応じて--ignore-caseオプションを指定する。

enumfunc
This plugin enumerates imported and exported functions from processes, dlls, and kernel drivers. Specifically, it handles functions imported by name or ordinal, functions exported by name or ordinal, and forwarded exports. The output will be very verbose in most cases (functions exported by ntdll, msvcrt, and kernel32 can reach 1000+ alone). So you can either reduce the verbosity by filtering criteria with the command-line options (shown below) or you can use look at the code in enumfunc.py and use it as an example of how to use the IAT and EAT parsing API functions in your own plugin. For example, the apihooks plugin leverages the imports and exports APIs to find functions in memory when checking for hooks.
このプラグインは、プロセス、DLL、カーネルドライバにインポートまたはそれらからエクスポートされる関数を列挙する。特に名前か序数でインポートされた関数、名前か序数でエクスポートされた関数、forwardedエクスポートを操作する。通常の使用のためには、とても詳細な出力だろう(ntdll, msvcrt, kernel32からエクスポートされた関数は、それぞれ1000以上に達する)。コマンドラインオプションのフィルタで削減を行う(下で述べる)か、enumfunc.pyのコードを見てIATとEATをパースするAPIのサンプルとして貴方自身のプラグインで利用することもできる。例えば、apihooksプラグインはメモリ上の関数がフックされているをチェックするためにインポートとエクスポートのAPIを利用している。
Also note this plugin is in the contrib directory, so you can pass that to --plugins like this:
このプラグインは、contribディレクトリにあるため、--pluginsオプションをこのように渡すことができる：

To use pool scanners for finding processes and kernel drivers instead of walking linked lists, use the -s option. This can be useful if you're trying to enumerate functions in hidden processes or drivers. An example of the remaining command-line options is shown below.
プロセスとカーネルドライバを見つけるためにリンクリストをたどるのではなく、プールスキャナを使うためには、-sオプションを指定する。隠されたプロセスやドライバの関数を列挙しようとする場合には有用です。残されたコマンドラインオプションは以下に示されます。

Process Memory
memmap
The memmap command shows you exactly which pages are memory resident, given a specific process DTB (or kernel DTB if you use this plugin on the Idle or System process). It shows you the virtual address of the page, the corresponding physical offset of the page, and the size of the page. The map information generated by this plugin comes from the underlying address space's get_available_addresses method.
memmapは、指定したプロセスDTB(もしくはアイドルかシステムプロセスに対しては、カーネルDTB)のどのページが物理メモリ上にあるかを表示する。ページの仮想アドレス、対応する物理アドレスとサイズを表示する。このプラグインが表示する情報は、アドレス空間のget_available_addressesメソッドで取得される。
As of 2.1, the new column DumpFileOffset helps you correlate the output of memmap with the dump file produced by the memdump plugin. For example, according to the output below, the page at virtual address 0x0000000000058000 in the System process's memory can be found at offset 0x00000000162ed000 of the win7_trial_64bit.raw file. After using memdump to extract the addressable memory of the System process to an individual file, you can find this page at offset 0x8000.
2.1から、DumpFileOffsetという新しい列で、memmapの出力とmemdumpによるダンプファイルの関連付けができるようになっている。例えば、下の出力例では、システムプロセスの仮想アドレス0x0000000000058000のページは、win7_trial_64bit.rawファイルの0x00000000162ed000オフセットに見つけられる。システムプロセスのメモリを個別のファイルにダンプした後に、そのファイルの0x8000オフセットにページが見つけられる。

memdump
To extract all memory resident pages in a process (see memmap for details) into an individual file, use the memdump command. Supply the output directory with -D or --dump-dir=DIR.

procdump
To dump a process's executable, use the procdump command. Optionally, pass the --unsafe or -u flags to bypass certain sanity checks used when parsing the PE header. Some malware will intentionally forge size fields in the PE header so that memory dumping tools fail.
プロセスの実行形式ファイルをダンプするためにprocdumpコマンドが使えます。オプションとして、--unsafeまたは-uオプションを指定するとPEヘッダをパースする際にいくつかの健全さのチェックがバイパスされます。
Use --memory to include slack space between the PE sections that aren't page aligned. Without --memory you'll get a file that more closely resembles the file on disk, before sections expanded.
--memoryオプションでページ位置に合っていないPEセクションのスラックスペースを含められます。--memoryオプションなしでは、セクションが拡大する前のディスク上のファイルによく似たファイルを取得することになります。

vadinfoは、プロセスのVADノードについての拡張された情報を表示します。以下のものを表示します。
- The address of the MMVAD structure in kernel memory
-
The starting and ending virtual addresses in process memory that the MMVAD structure pertains to
-
The VAD Tag
-
The VAD flags, control flags, etc
-
The name of the memory mapped file (if one exists)
-
The memory protection constant (permissions). Note there is a difference between the original protection and current protection. The original protection is derived from the flProtect parameter to VirtualAlloc. For example you can reserve memory (MEM_RESERVE) with protection PAGE_NOACCESS (original protection). Later, you can call VirtualAlloc again to commit (MEM_COMMIT) and specify PAGE_READWRITE (becomes current protection). The vadinfo command shows the original protection only. Thus, just because you see PAGE_NOACCESS here, it doesn't mean code in the region cannot be read, written, or executed.

-

-
メモリプロテクション定数(許可)。オリジナルのプロテクションと現在のプロテクションには違いがあることに注意。オリジナルのプロテクションは、VirtualAllocに対するflProtectパラメータからきている。例えば、PAGE_NOACCESSプロテクション(オリジナルのプロテクション)でメモリを予約(MEM_RESERVE)できる。その後、VirtualAllocを再び呼んで、PAGE_READWRITEプロテクションでコミット(MEM_COMMIT)することができる(現在のプロテクションになる)。vadinfoは、オリジナルのプロテクションしか表示しない。PAGE_NOACCESSと表示されているからといって、必ずしもそのメモリのコードが、リード、ライト、実行できないというわけではない。

If you want to view the balanced binary tree in Graphviz format, just add --output=dot --output-file=graph.dot to your command. Then you can open graph.dot in any Graphviz-compatible viewer. This plugin also supports color coding the output based on the regions that contain stacks, heaps, mapped files, DLLs, etc. A partial example is shown below using Omnigraffle:
Graphviza形式で、バランスされたツリーで表示させたければ、-output=dot --output-file=graph.dotオプションを指定する。そうすれば、Graphviz互換ビュアーで開くことができる。スタック、ヒープ、マップドファイル、DLLなどの領域で出力の色を変える設定もサポートしている。Omnigraffleを使った部分的な例。

vaddump
To extract the range of pages described by a VAD node, use the vaddump command. This is similar to memdump, except the pages belonging to each VAD node are placed in separate files (named according to the starting and ending addresses) instead of one large conglomerate file. If any pages in the range are not memory resident, they're padded with 0's using the address space's zread() method.
vaddumpコマンドは、VADノードの領域にあるページを出力する。
複合した大きな1ファイルの代わりに各VADノードに属するページが分割されたファイル(開始・終了アドレスによるファイル名)になること以外はmemdumpに似ている。物理メモリにどのページもない場合、アドレス空間のzread()メソッドによって0でパディングされる。

evtlogs
The evtlogs command extracts and parses binary event logs from memory. Binary event logs are found on Windows XP and 2003 machines, therefore this plugin only works on these architectures. These files are extracted from VAD of the services.exe process, parsed and dumped to a specified location.
evtlogsコマンドは、メモリ上のバイナリイベントログを抽出する。バイナリイベントログはWindows XPと2003に存在するので、これらのアーキテクチャ上でのみ有効である。service.exeプロセスのVADから抽出、パースされて指定された場所に出力される。

If the --verbose flag is used, SIDs are also evaluated and placed in the parsed output instead of the defaulting raw SID. This action takes longer to run, since the plugin has to calculate each of the service SID and user SID from registry entries.
--verboseオプションが指定されると、既定の加工していないSIDの代わりにSIDが評価されて表示される。この動作には比較すると長い時間がかかるが、各サービスSIDとユーザSIDをレジストリエントリから計算しているためです。
iehistory
This plugin recovers fragments of IE history index.dat cache files. It can find basic accessed links (via FTP or HTTP), redirected links (--REDR), and deleted entries (--LEAK). It applies to any process which loads and uses the wininet.dll library, not just Internet Explorer. Typically that includes Windows Explorer and even malware samples. For more information, see HowTo: Scan for Internet Cache/History and URLs.

Kernel Memory and Objects
modules
To view the list of kernel drivers loaded on the system, use the modules command. This walks the doubly-linked list of LDR_DATA_TABLE_ENTRY structures pointed to by PsLoadedModuleList. Similar to the pslist command, this relies on finding the KDBG structure. In rare cases, you may need to use kdbgscan to find the most appropriate KDBG structure address and then supply it to this plugin like --kdbg=ADDRESS.
modulesコマンドによって、システムにロードされていたカーネルドライバのリストを得ることがでます。PsLoadedModuleListが示す、LDR_DATA_TABLE_ENTRY構造体のダブルリンクリストを辿ります。pslistコマンドと同様に、KDBG構造体を頼りにします。レアケースでは、最も適切なKDBG構造体のアドレスをkdbgscanで見つけて、--kdbg=ADDRESSというように与える必要があるかもしれません。
>It cannot find hidden/unlinked kernel drivers, however modscan serves that purpose. Also, since this plugin uses list walking techniques, you typically can assume that the order the modules are displayed in the output is the order they were loaded on the system. For example, below, ntoskrnl.exe was first to load, followed by hal.dll, etc.
隠蔽された／リンクを外されたカーネルドライバを見つけることはできませんが、modscanがそのために使えます。ダブルリンクリストをたどるため、通常システムにロードされた順番に表示されていると考えることが可能です。例えば、下の例にあるように、ntoskrnl.exeが最初にロードされ、その後がhal.dllとなっているようにです。

## modscan
>The modscan command finds LDR_DATA_TABLE_ENTRY structures by scanning physical memory for pool tags. This can pick up previously unloaded drivers and drivers that have been hidden/unlinked by rootkits. Unlike modules the order of results has no relationship with the order in which the drivers loaded. As you can see below, DumpIt.sys was found at the lowest physical offset, but it was probably one of the last drivers to load (since it was used to acquire memory).
modscanコマンドは、物理メモリでpoolタグを検索してLDR_DATA_TABLE_ENTRY構造体を見つけます。これにより、アンロード済みのドライバとルートキットにより隠蔽／リンクを外されたドライバを見つけることが可能です。modulesコマンドとは違い、結果の順番はドライバがロードされた順番とは関係がありません。下の例で分かるように、DumpIt.sysが最も低い物理オフセットで見つかりましたが、おそらく最も最近ロードされたドライバの一つです(メモリダンプのために使われたドライバなので)。

>Similar to dlldump, if critical parts of the PE header are not memory resident, then rebuilding/extracting the driver may fail. Additionally, for drivers that are mapped in different sessions (like win32k.sys), there is currently no way to specify which session to use when acquiring the driver sample.
dlldumpと同様に、PEヘッダのクリティカルな部分がメモリに載っていない場合、ドライバの最構成／出力は失敗するかもしれません。更に、(win32k.sysのように)別のセッションにマップされたドライバに関しては、現在どのセッションを使ってドライバを取得するかを指定することはできません。
## ssdt
>To list the functions in the Native and GUI SSDTs, use the ssdt command. This displays the index, function name, and owning driver for each entry in the SSDT. Please note the following:
Windows has 4 SSDTs by default (you can add more with KeAddSystemServiceTable), but only 2 of them are used - one for Native functions in the NT module, and one for GUI functions in the win32k.sys module.
ssdtコマンドは、ネイティブとGUI SSDTを表示します。それぞれのSSDTエントリのインデックス、関数名、ドライバを表示します。以下のことに注意してください。Windowsはデフォルトで4つのSSDTを持っていますが、2つのみが使用されています。NTモジュール内のネイティブ関数とwin32k.sysモジュール内のGUI関数です。
>There are multiple ways to locate the SSDTs in memory. Most tools do it by finding the exported KeServiceDescriptorTable symbol in the NT module, but this is not the way Volatility works.
メモリ内のSSDTの場所を知るにはいくつかの方法があります。ほとんどツールは、NTモジュールでエクスポートされているKeServiceDescriptorTableシンボルを見つけて利用しますが、Volatilityは別の方法を使います。
>For x86 systems, Volatility scans for ETHREAD objects (see the thrdscan command) and gathers all unique ETHREAD.Tcb.ServiceTable pointers. This method is more robust and complete, because it can detect when rootkits make copies of the existing SSDTs and assign them to particular threads. Also see the threads command.
x86システムでは、VolatilityはETHREADオブジェクトを検索し(thrdscanコマンド参照)、ユニークなETHREAD.Tcb.ServiceTableポインタを集めます。この方法は、ルートキットがSSDTのコピーを作成して特定のスレッドに割り当てた時に検知できるため、より安定した完全な方法です。threadsコマンドを参照してください。
>For x64 systems (which do not have an ETHREAD.Tcb.ServiceTable member) Volatility disassembles code in ntKeAddSystemServiceTable and finds its references to the KeServiceDescriptorTable and KeServiceDescriptorTableShadow symbols.
x64システム(ETHREAD.Tcb.ServiceTableが存在しません)では、VolatilityはntKeAddSystemServiceTable内のコードを逆アセンブルしてKeServiceDescriptorTableとKeServiceDescriptorTableShadowのシンボルへのリファレンスを見つけます。
>The order and total number of functions in the SSDTs differ across operating system versions. Thus, Volatility stores the information in a per-profile (OS) dictionary which is auto-generated and cross-referenced using the ntoskrnl.exe, ntdll.dll, win32k.sys, user32.dll and gdi32.dll modules from the respective systems.
SSDT内の関数の順番と総数は、OSのバージョンによって異なります。そのため、Volatilityは、個別のシステムのntoskrnl.exe、ntdll.dll、win32k.sys、user32.dllおよびgdi32.dllモジュールを使って相互リファレンスを自動生成したプロファイル(OS)ごとの辞書に情報を出力します。

$ python vol.py -f ~/Desktop/win7_trial_64bit.raw --profile=Win7SP0x64 ssdt | egrep -v '(ntos|win32k)'
>Note that the NT module on your system may be ntkrnlpa.exe or ntkrnlmp.exe - so check that before using egrep of you'll be filtering the wrong module name. Also be aware that this isn't a hardened technique for finding hooks, as malware can load a driver named win32ktesting.sys and bypass your filter.
NTモジュールは、ntkrnlpa.exeやntkrnlmp.exeであるかもしれません。そのため、egrepを使う前に間違ったモジュール名でフィルタをしようとしていないかを確認してください。マルウェアは、win32ktesting.sysというような名前のドライバをロードしてフィルタを回避することの可能なので、必ずしも成功するテクニックではないことに注意してください。
## driverscan
>To find DRIVER_OBJECTs in physical memory using pool tag scanning, use the driverscan command. This is another way to locate kernel modules, although not all kernel modules have an associated DRIVER_OBJECT. The DRIVER_OBJECT is what contains the 28 IRP (Major Function) tables, thus the driverirp command is based on the methodology used by driverscan.

## dumpfiles
>An important concept that every computer scientist, especially those who have spent time doing operating system research, is intimately familiar with is that of caching. Files are cached in memory for system performance as they are accessed and used. This makes the cache a valuable source from a forensic perspective since we are able to retrieve files that were in use correctly, instead of file carving which does not make use of how items are mapped in memory. Files may not be completely mapped in memory (also for performance), so missing sections are zero padded. Files dumped from memory can then be processed with external tools.
>For more information see AAron Walter's post: MoVP 4.4 Cache Rules Everything Around Me(mory).
>There are several options in the dumpfiles plugin, for example:
-r REGEX, --regex=REGEX
Dump files matching REGEX
-i, --ignore-case Ignore case in pattern match
-o OFFSET, --offset=OFFSET
Dump files for Process with physical address OFFSET
-Q PHYSOFFSET, --physoffset=PHYSOFFSET
Dump File Object at physical address PHYSOFFSET
-D DUMP_DIR, --dump-dir=DUMP_DIR
Directory in which to dump extracted files
-S SUMMARY_FILE, --summary-file=SUMMARY_FILE
File where to store summary information
-p PID, --pid=PID Operate on these Process IDs (comma-separated)
-n, --name Include extracted filename in output file path
-u, --unsafe Relax safety constraints for more data
-F FILTER, --filter=FILTER
Filters to apply (comma-separated)
>By default, dumpfiles iterates through the VAD and extracts all files that are mapped as DataSectionObject, ImageSectionObject or SharedCacheMap. As an investigator, however, you may want to perform a more targeted search. You can use the -r and -i flags to specify a case-insensitive regex of a filename. In the output below, you can see where the file was dumped from (DataSectionObject, ImageSectionObject or SharedCacheMap), the offset of the _FILE_OBJECT, the PID of the process whose VAD contained the file and the file path on disk:

Output includes the virtual offset of the _TCPT_OBJECT by default. The physical offset can be obtained with the -P switch.
connscan
To find _TCPT_OBJECT structures using pool tag scanning, use the connscan command. This can find artifacts from previous connections that have since been terminated, in addition to the active ones. In the output below, you'll notice some fields have been partially overwritten, but some of the information is still accurate. For example, the very last entry's Pid field is 0, but all other fields are still in tact. Thus, while it may find false positives sometimes, you also get the benefit of detecting as much information as possible.
This command is for x86 and x64 Windows XP and Windows 2003 Server only.

netscan
To scan for network artifacts in 32- and 64-bit Windows Vista, Windows 2008 Server and Windows 7 memory dumps, use the netscan command. This finds TCP endpoints, TCP listeners, UDP endpoints, and UDP listeners. It distinguishes between IPv4 and IPv6, prints the local and remote IP (if applicable), the local and remote port (if applicable), the time when the socket was bound or when the connection was established, and the current state (for TCP connections only). For more information, see http://mnin.blogspot.com/2011/03/volatilitys-new-netscan-module.html Volatility's New Netscan Module.
Please note the following:
The netscan command uses pool tag scanning
There are at least 2 alternate ways to enumerate connections and sockets on Vista+ operating systems. One of them is using partitions and dynamic hash tables, which is how the netstat.exe utility on Windows systems works. The other involves bitmaps and port pools.

printkey
To display the subkeys, values, data, and data types contained within a specified registry key, use the printkey command. By default, printkey will search all hives and print the key information (if found) for the requested key. Therefore, if the key is located in more than one hive, the information for the key will be printed for each hive that contains it.
Say you want to traverse into the HKEY_LOCAL_MACHINE\Microsoft\Security Center\Svc key. You can do that in the following manner. Note: if you're running Volatility on Windows, enclose the key in double quotes (see issue 166).
$ python vol.py -f ~/Desktop/win7_trial_64bit.raw --profile=Win7SP0x64 printkey -K "Microsoft\Security Center\Svc"

Here you can see how the output appears when multiple hives (DEFAULT and ntuser.dat) contain the same key "Software\Microsoft\Windows NT\CurrentVersion".
$ python vol.py -f ~/Desktop/win7_trial_64bit.raw --profile=Win7SP0x64 printkey -K "Software\Microsoft\Windows NT\CurrentVersion"

If you want to limit your search to a specific hive, printkey also accepts a virtual address to the hive. For example, to see the contents of HKEY_LOCAL_MACHINE, use the command below. Note: the offset is taken from the previous hivelist output.
$ python vol.py -f ~/Desktop/win7_trial_64bit.raw --profile=Win7SP0x64 printkey -o 0xfffff8a000a15010

hashdump
To extract and decrypt cached domain credentials stored in the registry, use the hashdump command. For more information, see BDG's Cached Domain Credentials and SANS Forensics 2009 - Memory Forensics and Registry Analysis.
To use hashdump, pass the virtual address of the SYSTEM hive as -y and the virtual address of the SAM hive as -s, like this:
$ python vol.py hashdump -f image.dd -y 0xe1035b60 -s 0xe165cb60

Hashes can now be cracked using John the Ripper, rainbow tables, etc.
It is possible that a registry key is not available in memory. When this happens, you may see the following error:
"ERROR : volatility.plugins.registry.lsadump: Unable to read hashes from registry"
You can try to see if the correct keys are available: "CurrentControlSet\Control\lsa" from SYSTEM and "SAM\Domains\Account" from SAM. First you need to get the "CurrentControlSet", for this we can use volshell (replace [REGISTRY ADDRESS](SYSTEM) below with the offset you get from hivelist), for example:
$ python vol.py -f XPSP3.vmem --profile=WinXPSP3x86 volshell
Volatility Foundation Volatility Framework 2.4
Current context: process System, pid=4, ppid=0 DTB=0x319000
Welcome to volshell Current memory image is:
file:///XPSP3.vmem
To get help, type 'hh()'
>>> import volatility.win32.hashdump as h
>>> import volatility.win32.hive as hive
>>> addr_space = utils.load_as(self._config)
>>> sysaddr = hive.HiveAddressSpace(addr_space, self._config, [SYSTEM REGISTRY ADDRESS])
>>> print h.find_control_set(sysaddr)
1
>>> ^D
Then you can use the printkey plugin to make sure the keys and their data are there. Since the "CurrentControlSet" is 1 in our previous example, we use "ControlSet001" in the first command:
$ python vol.py -f XPSP3.vmem --profile=WinXPSP3x86 printkey -K "ControlSet001\Control\lsa"
$ python vol.py -f XPSP3.vmem --profile=WinXPSP3x86 printkey -K "SAM\Domains\Account"
If the key is missing you should see an error message:
"The requested key could not be found in the hive(s) searched"
lsadump
To dump LSA secrets from the registry, use the lsadump command. This exposes information such as the default password (for systems with autologin enabled), the RDP public key, and credentials used by DPAPI.
For more information, see BDG's Decrypting LSA Secrets.
To use lsadump, pass the virtual address of the SYSTEM hive as the -y parameter and the virtual address of the SECURITY hive as the -s parameter.
$ python vol.py -f laqma.vmem lsadump -y 0xe1035b60 -s 0xe16a6b60

Another option is to use the --output=body option for TSK 3.x bodyfile format. You can use this output option when you want to combine output from timeliner, mftparser and timeliner. You can also include a machine identifier in the bodyfile header with the --machine flag (this is useful when combining timelines from multiple machines). Only ITEMPOS and FILE_ENTRY items are output with the bodyfile format:

getservicesids
The getservicesids command calculates the SIDs for services on a machine and outputs them in Python dictionary format for future use. The service names are taken from the registry ("SYSTEM\CurrentControlSet\Services"). For more information on how these SIDs are calculated, see Timeliner Release Documentation (pdf). Example output can be seen below:

dumpregistry
The dumpregistry plugin allows you to dump a registry hive to disk. It works on all supported Windows versions (Windows XP-8.1). By default the plugin will dump all registry files (including virtual registries like HARDWARE) found to disk, however you may specify the virtual offset for a specific hive in order to only dump one registry at a time. One caveat about using this plugin (or the dumpfiles plugin) is that there may be holes in the dumped registry file, so offline registry tools may crash if they are not made robustly to handle "corrupt" files. These holes are denoted in the text output with lines like Physical layer returned None for index 2000, filling with NULL. Example output is shown below:
$ python vol.py -f voltest.dmp --profile=Win7SP1x86 dumpregistry -D output

Crash Dumps, Hibernation, and Conversion
Volatility supports memory dumps in several different formats, to ensure the highest compatibility with different acquisition tools. You can analyze hibernation files, crash dumps, virtualbox core dumps, etc in the same way as any raw memory dump and Volatility will detect the underlying file format and apply the appropriate address space. You can also convert between file formats.
crashinfo
Information from the crashdump header can be printed using the crashinfo command. You will see information like that of the Microsoft dumpcheck utility.

This conversion be necessary if some of your other forensic tools only support reading raw memory dumps.
The profile should be specified for this command, so if you don't know it already, use the [or Command Reference#kdbgscan kdbgscan commands first. The output file is specified with the -O flag. The progress is updated as the file is converted:

mbrparser
Scans for and parses potential Master Boot Records (MBRs). There are different options for finding MBRs and filtering output. For more information please see Recovering Master Boot Records from Memory. While this plugin was written with Windows bootkits in mind, it can also be used with memory samples from other systems.
When run without any extra options, mbrparser scans for and returns information all potential MBRs defined by signature ('\x55\xaa') found in memory. Information includes: disassembly of bootcode (must have distorm3 installed) and partition information. This will most likely have false positives.
If distorm3 is not installed, the -H/--hex option can be used to get the entire bootcode section in hex instead of disassembly:
$ python vol.py -f [sample] mbrparser -H
If the physical offset of the MBR is known, it can be specified with the -o/--offset= option for example:
$ python vol.py -f [sample] -o 0x600 mbrparser
If the md5 hash of the desired bootcode is known, one can be specified using either the -M/--hash (the hash of bootcode up to the RET instruction) or -F/--fullhash (the hash of full bootcode) option.
$ python vol.py mbrparser -f AnalysisXPSP3.vmem -M 6010862faee6d5e314aba791380d4f41
or
$ python vol.py mbrparser -f AnalysisXPSP3.vmem -F 6010862faee6d5e314aba791380d4f41
In order to cut down on false positives there is a -C/--check option that checks the partition table for one bootable partition that has a known, nonempty type (NTFS, FAT*, etc).
$ python vol.py -f [sample] -C mbrparser
There is also an option to change the offset for the start of the disassembly. This can be useful for investigating machines (like Windows XP) that only copy the part of the MBR bootcode that has not yet executed. For example, before changing the offset:
$ python vol.py mbrparser -f AnalysisXPSP3.vmem -o 0x600

mftparser
This plugin scans for potential Master File Table (MFT) entries in memory (using "FILE" and "BAAD" signatures) and prints out information for certain attributes, currently: $FILE_NAME ($FN), $STANDARD_INFORMATION ($SI), $FN and $SI attributes from the $ATTRIBUTE_LIST, $OBJECT_ID (default output only) and resident $DATA. This plugin has room for expansion, however, and VTypes for other attributes are already included. For more information please see Reconstructing the MBR and MFT from Memory (OMFW 2012 slides). Options of interest include:
--machine - Machine name to add to timeline header (useful when combining timelines from multiple machines)
-D/--dump-dir - Output directory to which resident data files are dumped
--output=body - print output in Sleuthkit 3.X body format
--no-check - Prints out all entries including those with null timestamps
-E/--entry-size - Changes the default 1024 byte MFT entry size.
-O/--offset - Prints out the MFT entry at a give offset (comma delimited)
This plugin may take a while to run before seeing output, since it scans first and then builds the directory tree for full file paths.
Example (default output):
$ python vol.py -f Bob.vmem mftparser

The bodyfile output is also an option. It is recommended that the output be stored in a file using the --output-file option, since it is quite lengthy. The following shows creating a bodyfile using mftparser while dumping resident files. You can also see a file of interest that is created on the system (f.txt) which happens to be recovered in the output directory:

Miscellaneous
strings
For a given image and a file with lines of the form <decimal_offset>:<string>, or <decimal_offset> <string>, output the corresponding process and virtual addresses where that string can be found. Expected input for this tool is the output of Microsoft Sysinternals' Strings utility, or another utility that provides similarly formatted offset:string mappings. Note that the input offsets are physical offsets from the start of the file/image.
Sysinternals Strings can be used on Linux/Mac using Wine. Output should be redirected to a file to be fed to the Volatility strings plugin. If you're using GNU strings command, use the -td flags to produce offsets in decimal (the plugin does not accept hex offsets). Some example usages are as follows:
Windows
C:\> strings.exe –q –o -accepteula win7.dd > win7_strings.txt
It can take a while for the Sysinternals strings program to finish. The –q and –o switches are imperative, since they make sure the header is not output (-q) and that there is an offset for each line (-o).
Linux/Mac
You can use the Sysinternals strings program with wine:
$ wine strings.exe –q –o -accepteula win7.dd > win7_strings.txt
You can also use the GNU strings utility that comes with Linux and Mac (Note: the default strings utility on Mac does not have Unicode support. You can install the GNU binutils package in order to get a strings utility that does). You should use the -td flags to get the decimal offset and will have to make a second pass with the -el flags in order to get (little endian) Unicode strings. Notice that the second pass appends (>>) to the existing file:
$ strings -a -td win7.dd > win7_strings.txt
$ strings -a -td -el win7.dd >> win7_strings.txt
The result should be a text file that contains the offset and strings from the image for example:
16392:@@@
17409:
17441:
17473:"""
17505:###
17537:$$$
17569:%%%
17601:&&&
17633:'''
17665:(((
17697:)))
17729:***
EnCase Keyword Export
You can also use EnCase to export keywords and offsets in this format with some tweaking. One thing to note is that EnCase exports text in UTF-16 with a BOM of (U+FEFF) which can cause issues with the strings plugin. An example look at the exported keyword file:
File Offset Hit Text
114923 DHCP
114967 DHCP
115892 DHCP
115922 DHCP
115952 DHCP
116319 DHCP
[snip]
Now tweaking the file by removing the header and tabs we have:
114923:DHCP
114967:DHCP
115892:DHCP
115922:DHCP
115952:DHCP
116319:DHCP
[snip]
We can see that it is UTF-16 and has a BOM of (U+FEFF) by using a hex editor.
$ file export.txt
export.txt: Little-endian UTF-16 Unicode text, with CRLF, CR line terminators
$ xxd export.txt |less
0000000: fffe 3100 3100 3400 3900 3200 3300 3a00 ..1.1.4.9.2.3.:.
[snip]
We have to convert this to ANSI or UTF-8. In Windows you can open the text file and use the "Save As" dialog to save the file as ANSI (in the "Encoding" drop-down menu). In Linux you can use iconv:
$ iconv -f UTF-16 -t UTF-8 export.txt > export1.txt
NOTE: You must make sure there are NO blank lines in your final "strings" file.
Now we can see a difference in how these two files are handled:
$ python vol.py -f Bob.vmem --profile=WinXPSP2x86 strings -s export.txt
Volatility Foundation Volatility Framework 2.4
ERROR : volatility.plugins.strings: String file format invalid.

NOTE: The Volatility strings output is very verbose and it is best to redirect or save to a file. The following command saves the output using the --output-file option and filename "win7_vol_strings.txt"
$ python vol.py --profile=Win7SP0x86 strings –f win7.dd –s win7_strings.txt --output-file=win7_vol_strings.txt
By default strings will only provide output for processes found by walking the doubly linked list pointed to by PsActiveProcessHead (see pslist) in addition to kernel addresses. strings can also provide output for hidden processes (see psscan) by using the (capital) -S switch:
$ python vol.py --profile=Win7SP0x86 strings –f win7.dd –s win7_strings.txt --output-file=win7_vol_strings.txt -S
Also an EPROCESS offset can be provided:
$ python vol.py --profile=Win7SP0x86 strings –f win7.dd –s win7_strings.txt --output-file=win7_vol_strings.txt -o 0x04a291a8
The strings plugin takes a while to complete. When it completes, you should have an output file with each line in the following format:
physical_address [kernel_or_pid:virtual_address] string
In the example output you can see PIDs/kernel references:

Once you have the strings output, you can see which process(es) have the suspicious string in memory and can then narrow your focus. You can grep for the string or pattern depending on the context you were given. For example, if you are looking for a particular command:
$ grep [command or pattern] win7_vol_strings.txt > strings_of_interest.txt
For all IPs:
$ cat win7_vol_strings.txt | \
perl -e 'while(<>){if(/(?:(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.){3}(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)/){print $_;}}' > IPs.txt
For all URLs:
$ cat win7_vol_strings.txt | \
perl -e 'while(<>){ if(/(http|https|ftp|mail)\:[\/\w.]+/){print $_;}}' > URLs.txt
Depending on the context, your searches will vary.
volshell
If you want to interactively explore a memory image, use the volshell command. This gives you an interface similar to WinDbg into the memory dump. For example, you can:
List processes
Switch into a process's context
Display types of structures/objects
Overlay a type over a given address
Walk linked lists
Disassemble code at a given address
Note: volshell can take advantage of IPython if you have it installed. This will add tab-completion and saved command history.
To break into a volshell:
$ python vol.py --profile=Win7SP0x86 -f win7.dmp volshell

The db, dd, dt, and dis commands all accept an optional "space" parameter which allows you to specify an address space. You will see different data depending on which address space you're using. Volshell has some defaults and rules that are important to note:
If you don't supply an address space and have not switched into a process context with cc, then you'll be using the default kernel space (System process).
If you don't supply an address space and have switched into a process context with cc, then you'll be using the space of the active/current process.
If you explicitly supply an address space, the one you supplied will be used.
Imagine you're using one of the scan commands (psscan, connscan, etc.) and you think it has picked up a false positive. The scan commands output a physical offset (offset into the memory dump file). You want to explore the data around the potential false positive to determine for yourself if any structure members appear sane or not. One way you could do that is by opening the memory dump in a hex viewer and going to the physical offset to view the raw bytes. However, a better way is to use volshell and overlay the structure question to the alleged physical offset. This allows you to see the fields interpreted as their intended type (DWORD, string, short, etc.)
Here's an example. First instantiate a physical address space:
>>> physical_space = utils.load_as(self._config, astype = 'physical')
Assuming the alleged false positive for an EPROCESS is at 0x433308, you would then do:
>>> dt("_EPROCESS", 0x433308, physical_space)
[_EPROCESS _EPROCESS] @ 0x00433308
0x0 : Pcb 4403976
0x6c : ProcessLock 4404084
0x70 : CreateTime 1970-01-01 00:00:00
0x78 : ExitTime 1970-01-01 00:00:00
...
Another neat trick is to use volshell in a non-interactive manner. For example, say you want to translate an address in kernel memory to its corresponding physical offset.
$ echo "hex(addrspace().vtop(0x823c8830))" | python vol.py -f stuxnet.vmem volshell
Volatility Foundation Volatility Framework 2.4
Current context: process System, pid=4, ppid=0 DTB=0x319000
Welcome to volshell Current memory image is:
file:///mem/stuxnet.vmem
To get help, type 'hh()'
>>> '0x25c8830'
Thus the kernel address 0x823c8830 translates to physical offset 0x25c8830 in the memory dump file.
You can execute multiple commands sequentially like this:
$ echo "cc(pid=4); dd(0x10000)" | [...]
For more information, see BDG's Introducing Volshell.
bioskbd
To read keystrokes from the BIOS area of memory, use the bioskbd command. This can reveal passwords typed into HP, Intel, and Lenovo BIOS and SafeBoot, TrueCrypt, and BitLocker software. Depending on the tool used to acquire memory, not all memory samples will contain the necessary BIOS area. For more information, see Andreas Schuster's Reading Passwords From the Keyboard Buffer, David Sharpe's Duplicating Volatility Bioskbd Command Function on Live Windows Systems, and Jonathan Brossard's Bypassing pre-boot authentication passwords by instrumenting the BIOS keyboard buffer.
patcher
The patcher plugin accepts a single argument of '-x' followed by an XML file. The XML file then specifies any required patches as in the following example:
<patchfile>
<patchinfo method="pagescan" name="Some Descriptive Name">
<constraints>
<match offset="0x123">554433221100</match>
</constraints>
<patches>
<setbytes offset="0x234">001122334455</setbytes>
</patches>
</patchinfo>
<patchinfo>
...
</patchinfo>
</patchfile>
The XML root element is always patchfile, and contains any number of patchinfo elements. When the patchfile is run, it will scan over the memory once for each patchinfo, attempting to scan using the method specified in the method attribute. Currently the only support method is pagescan and this must be explicitly declared in each patchinfo element.
Each pagescan type patchinfo element contains a single constraints element and a single patches element. The scan then proceeds over each page in memory, verifying that all constraints are met, and if so, the instructions specified in the patches element are carried out.
The constraints element contains any number of match elements which take a specific offset attribute (specifying where within the page the match should occur) and then contain a hexadecimal string for the bytes that are supposed to match.
The patches element contains any number of setbytes elements which take a specific offset attribute (specifying where with the page the patch should modify data) and then contains a hexidecimal string for the bytes that should be written into the page.
Note: When running the patcher plugin, there will be no modification made to memory unless the write option (-w) has been specified on the command line.
pagecheck
The pagecheck plugin uses a kernel DTB (from the System/Idle process) and determines which pages should be memory resident (using the AddressSpace.get_available_pages method). For each page, it attempts to access the page data and reports details, such as the PDE and PTE addresses if the attempt fails. This is a diagnostic plugin, usually helpful in troubleshooting "holes" in an address space.
This plugin is not well-supported. It is in the contrib directory and currently only works with non-PAE x86 address spaces.

If you don't want to do the extra step of importing, you can use the --output=xlsx option with --output-file=[FILE](OUTPUT) to save directly an Excel 2007 file. Note: You must have OpenPyxl installed for this.
$ python vol.py -f XPSP3x86.vmem timeliner --output=xlsx --output-file=output.xlsx
Another option is to use the --output=body option for TSK 3.x bodyfile format. You can use this output option when you want to combine output from timeliner, mftparser and shellbags.
By default everything except the registry LastWrite timestamps are included in the output of timeliner, this is because obtaining the registry timestamps is quite labor intensive. In order to add them to the output, simply add the --type=Registry option when you run Volatility. You can also limit your focus of registry timestamps by listing a specific registry name (like --hive=SYSTEM) or user (--user=Jim) or both (--hive=UsrClass.dat --user=jim). These options are case insensitive.
$ python vol.py -f win7SP1x86.vmem --profile=Win7SP1x86 timeliner --output=body --output-file=output.body --type=Registry --user=Jim --hive=UsrClass.dat
