- マルウェアタイプ: 身代金要求型不正プログラム(ランサムウェア)
- 破壊活動の有無: なし
- 暗号化: なし
- 感染報告の有無: はい
概要
マルウェアは、他のマルウェアに作成されるか、悪意あるWebサイトからユーザが誤ってダウンロードすることによりコンピュータに侵入します。
詳細
侵入方法
マルウェアは、他のマルウェアに作成されるか、悪意あるWebサイトからユーザが誤ってダウンロードすることによりコンピュータに侵入します。
インストール
マルウェアは、以下のファイルを作成します。
- %System Root%\qibfmqkeM5.log → contains list of files it was unable to encrypt
- %Temp%\M5-{10 random numbers}.dll → performs looking for target files
- %Temp%\M5-{10 random numbers}.dll → performs encryption of target files
(註:%System Root%フォルダは、オペレーティングシステム(OS)が存在する場所で、いずれのOSでも通常、 "C:" です。.. %Temp%フォルダは、一時的にファイルが保存されるフォルダで、いずれのオペレーティングシステム(OS)でも通常、 "C:\Windows\Temp" です。.)
マルウェアは、以下のプロセスを追加します。
- {Malware Directory}\{Malware File Name} +
- rundll32 %Temp%\M5-{10 random numbers}.dll,_run@16 {Drive Letter} → looks for files to encrypt
- rundll32 %Temp%\M5-{10 random numbers}.dll,_run@16 [1|2] → encrypts files
- vssadmin delete shadows /all /for={Drive Letter} → deletes volume shadow copies of affected drives
- vssadmin Resize ShadowStorage /MaxSize=320MB /for={Drive Letter} /on={Drive Letter} → resizes the maximum amount of storage space that can be used for shadow copy storage
- vssadmin Resize ShadowStorage /MaxSize=unbounded /for={Drive Letter} /on={Drive Letter} → resizes the maximum amount of storage space that can be used for shadow copy storage
- cipher /W:{Drive Letter} → wipes deleted files of affected drives
- wmic shadowcopy delete → deletes shadow copies
(註:%Temp%フォルダは、一時的にファイルが保存されるフォルダで、いずれのオペレーティングシステム(OS)でも通常、 "C:\Windows\Temp" です。.)
他のシステム変更
マルウェアは、以下のレジストリ値を変更します。
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\
Windows\CurrentVersion\Policies\
System
legalnoticecaption = "Locked By MegaCortex"
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\
Windows\CurrentVersion\Policies\
System
legalnoticetext = "Contact: {BLOCKED}iareimann@mail.com or {BLOCKED}lerman@mail.com"

対応方法
手順 1
Windows XP、Windows Vista および Windows 7 のユーザは、コンピュータからマルウェアもしくはアドウェア等を完全に削除するために、ウイルス検索の実行前には必ず「システムの復元」を無効にしてください。
手順 2
このマルウェアもしくはアドウェア等の実行により、手順中に記載されたすべてのファイル、フォルダおよびレジストリキーや値がコンピュータにインストールされるとは限りません。インストールが不完全である場合の他、オペレーティングシステム(OS)の条件によりインストールがされない場合が考えられます。手順中に記載されたファイル/フォルダ/レジストリ情報が確認されない場合、該当の手順の操作は不要ですので、次の手順に進んでください。
手順 3
変更されたレジストリ値を修正します。
警告:レジストリはWindowsの構成情報が格納されているデータベースであり、レジストリの編集内容に問題があると、システムが正常に動作しなくなる場合があります。
事前に意図的に対象の設定を変更していた場合は、意図するオリジナルの設定に戻してください。変更する値が分からない場合は、システム管理者にお尋ねいただき、レジストリの編集はお客様の責任として行なって頂くようお願いいたします。弊社ではレジストリの編集による如何なる問題に対しても補償いたしかねます。
レジストリの編集前にこちらをご参照ください。
