Type: Worm
Systems Affected: Windows



When W32.Beagle.DS@mm is executed, it performs the following actions:

  1. Displays the following message:

    Can't find a viewer associated with the file.

  2. Creates the following files:

    • %Windir%\vcualts32.exe
    • %System%\lmovie.exe
    • %System%\lmovie.exeopen
    • %System%\lmovie.exeopenopen

      Notes:
    • %Windir% is a variable that refers to the Windows installation folder. By default, this is C:\Windows (Windows 95/98/Me/XP) or C:\Winnt (Windows NT/2000).
    • %System% is a variable that refers to the System folder. By default this is C:\Windows\System (Windows 95/98/Me), C:\Winnt\System32 (Windows NT/2000), or C:\Windows\System32 (Windows XP).

  3. Adds the value:

    "MovieM" = "%System%\lmovie.exe"

    to the registry subkey:

    HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Run

    so that it runs every time Windows starts.

  4. Creates a back door by opening and listening for commands on TCP port 6777.

  5. Attempts to delete the registry values:

    "My AV"
    "Zone Labs Client Ex"
    "9XHtProtect"
    "Antivirus"
    "Special Firewall Service"
    "service"
    "Tiny AV"

    "HtProtect"
    "NetDy"
    "Jammer2nd"
    "FirewallSvr"
    "MsInfo"
    "SysMonXP"
    "EasyAV"
    "PandaAVEngine"
    "Norton Antivirus AV"
    "KasperskyAVEng"
    "SkynetsRevenge"
    "ICQ Net"

    from the registry subkeys:

    HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run

  6. Gathers email addresses from files with the following extensions:

    • .wab

  8. Uses its own SMTP engine to send email messages to any addresses found.
    The email message constructed by the worm typically has the following characteristics:

    From: [SPOOFED]

    Subject:
    One of the following:

    • Will You Be My Valentine?
    • Love you with all my heart!
    • See you tonight!
    • Come Be With Me, my Love!
    • My dream is coming true!

      Message Body:
      One of the following:

    • Click to attachment to load a picture
      Love at the lips was touch
      As sweet as I could bear;
      And once that seemed too much;
      I lived on air
      That crossed me from sweet things,
      The flow of - was it musk
      From hidden grapevine springs
      Down hill at dusk?
      I had the swirl and ache
      From sprays of honeysuckle
      That when they re gathered shake
      Dew on the knuckle.
      I craved strong sweets, but those
      Seemed strong when I was young;
      The petal of the rose
      It was that stung.
      Now no joy but lacks salt
      That is not dashed with pain
      And weariness and fault;
      I crave the stain
      Of tears, the aftermark
      Of almost too much love,
      The sweet of bitter bark
      And burning clove.
      When stiff and sore and scarred
      I take away my hand
      From leaning on it hard
      In grass and sand
      The hurt is not enough:
      I long for weight and strength
      To feel the earth as rough
      To all my length.

    • Click to attachment to load a movie
      I woke up in a white room
      with white lace curtains.
      Snow covered landscape;
      I.m in Memphis for certain
      Yesterday, it took over three hours
      just to travel the last twenty miles.
      But nothing is like my wife.s family
      always being greeted with smiles
      I was hoping for a White Christmas.
      You.d be surprise how simple I am.
      Be careful what you wish for
      God may be listening to your plan.
      Most of the nation is covered
      with that dangerous and beautiful thing
      I am grateful for arriving safely
      for my wife.s happiness is everything.
      She wanted to see her family,
      her father, uncles and aunts.
      I ve kept her in Southwest Texas too long;
      this trip I most willingly grant.
      So, here we are now
      in a snowy southern wonderland.
      Waiting for Christmas dinner to come;
      a present only my wife can understand

    • Execute attachment to load a movie
      A stranger came to the door at eve,
      And he spoke the bridegroom fair.
      He bore a green-white stick in his hand,
      And, for all burden, care.
      He asked with the eyes more than the lips
      For a shelter for the night,
      And he turned and looked at the road afar
      Without a window light.
      The bridegroom came forth into the porch
      With, "Let us look at the sky,
      And question what of the night to be,
      Stranger, you and I.
      "The woodbine leaves littered the yard,
      The woodbine berries were blue,
      Autumn, yes, winter was in the wind;
      "Stranger, I wish I knew."
      Within, the bride in the dusk alone
      Bent over the open fire,
      Her face rose-red with the glowing coal
      And the thought of the heart's desire.
      The bridegroom looked at the weary road,
      Yet saw but her within,
      And wished her heart in a case of gold
      And pinned with a silver pin.
      The bridegroom thought it little to give
      A dole of bread, a purse,
      A heartfelt prayer for the poor of God,
      Or for the rich a curse;
      But whether or not a man was asked
      To mar the love of two
      by harboring woe in the bridal house,
      The bridegroom wished he knew.

      Attachment:
      One of the following:

    • love_me.exe
    • mplay.exe
    • love_me_now.exe

  9. Attempts to copy itself to all folders containing the string SHAR by creating the following files:

    • kate beckinsale nude pictures.exe
    • jenna elfman sex anal deepthroat

Recommendations

Symantec Security Response encourages all users and administrators to adhere to the following basic security "best practices":

  • Use a firewall to block all incoming connections from the Internet to services that should not be publicly available. By default, you should deny all incoming connections and only allow services you explicitly want to offer to the outside world.
  • Enforce a password policy. Complex passwords make it difficult to crack password files on compromised computers. This helps to prevent or limit damage when a computer is compromised.
  • Ensure that programs and users of the computer use the lowest level of privileges necessary to complete a task. When prompted for a root or UAC password, ensure that the program asking for administration-level access is a legitimate application.
  • Disable AutoPlay to prevent the automatic launching of executable files on network and removable drives, and disconnect the drives when not required. If write access is not required, enable read-only mode if the option is available.
  • Turn off file sharing if not needed. If file sharing is required, use ACLs and password protection to limit access. Disable anonymous access to shared folders. Grant access only to user accounts with strong passwords to folders that must be shared.
  • Turn off and remove unnecessary services. By default, many operating systems install auxiliary services that are not critical. These services are avenues of attack. If they are removed, threats have less avenues of attack.
  • If a threat exploits one or more network services, disable, or block access to, those services until a patch is applied.
  • Always keep your patch levels up-to-date, especially on computers that host public services and are accessible through the firewall, such as HTTP, FTP, mail, and DNS services.
  • Configure your email server to block or remove email that contains file attachments that are commonly used to spread threats, such as .vbs, .bat, .exe, .pif and .scr files.
  • Isolate compromised computers quickly to prevent threats from spreading further. Perform a forensic analysis and restore the computers using trusted media.
  • Train employees not to open attachments unless they are expecting them. Also, do not execute software that is downloaded from the Internet unless it has been scanned for viruses. Simply visiting a compromised Web site can cause infection if certain browser vulnerabilities are not patched.
  • If Bluetooth is not required for mobile devices, it should be turned off. If you require its use, ensure that the device's visibility is set to "Hidden" so that it cannot be scanned by other Bluetooth devices. If device pairing must be used, ensure that all devices are set to "Unauthorized", requiring authorization for each connection request. Do not accept applications that are unsigned or sent from unknown sources.

Also Known As: Win32/Bagle.DW [Computer Assoc, Email-Worm.Win32.Bagle.ae [Kas, W32/Bagle.du@MM [McAfee], W32/Bagle-{CO, CQ} [Sophos], WORM_BAGLE.EW [Trend Micro]
Type: Worm
Systems Affected: Windows


The following instructions pertain to all current and recent Symantec antivirus products, including the Symantec AntiVirus and Norton AntiVirus product lines.

  1. Disable System Restore (Windows Me/XP).
  2. Update the virus definitions.
  3. Run a full system scan and delete all the files detected.
  4. Delete any values added to the registry.
For specific details on each of these steps, read the following instructions.

1. To disable System Restore (Windows Me/XP)
If you are running Windows Me or Windows XP, we recommend that you temporarily turn off System Restore. Windows Me/XP uses this feature, which is enabled by default, to restore the files on your computer in case they become damaged. If a virus, worm, or Trojan infects a computer, System Restore may back up the virus, worm, or Trojan on the computer.

Windows prevents outside programs, including antivirus programs, from modifying System Restore. Therefore, antivirus programs or tools cannot remove threats in the System Restore folder. As a result, System Restore has the potential of restoring an infected file on your computer, even after you have cleaned the infected files from all the other locations.

Also, a virus scan may detect a threat in the System Restore folder even though you have removed the threat.

For instructions on how to turn off System Restore, read your Windows documentation, or one of the following articles:
Note:
When you are completely finished with the removal procedure and are satisfied that the threat has been removed, reenable System Restore by following the instructions in the aforementioned documents.

For additional information, and an alternative to disabling Windows Me System Restore, see the Microsoft Knowledge Base article: Antivirus Tools Cannot Clean Infected Files in the _Restore Folder (Article ID: Q263455).

2. To update the virus definitions
Symantec Security Response fully tests all the virus definitions for quality assurance before they are posted to our servers. There are two ways to obtain the most recent virus definitions:
  • Running LiveUpdate, which is the easiest way to obtain virus definitions:
    • If you use Norton AntiVirus 2006, Symantec AntiVirus Corporate Edition 10.0, or newer products, LiveUpdate definitions are updated daily. These products include newer technology.
    • If you use Norton AntiVirus 2005, Symantec AntiVirus Corporate Edition 9.0, or earlier products, LiveUpdate definitions are updated weekly. The exception is major outbreaks, when definitions are updated more often.
  • Downloading the definitions using the Intelligent Updater: The Intelligent Updater virus definitions are posted daily. You should download the definitions from the Symantec Security Response Web site and manually install them. To determine whether definitions for this threat are available by the Intelligent Updater, refer to Virus Definitions (Intelligent Updater).

    The latest Intelligent Updater virus definitions can be obtained here: Intelligent Updater virus definitions. For detailed instructions read the document: How to update virus definition files using the Intelligent Updater.

3. To scan for and delete the infected files
  1. Start your Symantec antivirus program and make sure that it is configured to scan all the files.
  2. Run a full system scan.
  3. If any files are detected, click Delete.

Important: If you are unable to start your Symantec antivirus product or the product reports that it cannot delete a detected file, you may need to stop the risk from running in order to remove it. To do this, run the scan in Safe mode. For instructions, read the document, How to start the computer in Safe Mode . Once you have restarted in Safe mode, run the scan again.

After the files are deleted, restart the computer in Normal mode and proceed with the next section.

Warning messages may be displayed when the computer is restarted, since the threat may not be fully removed at this point. You can ignore these messages and click OK. These messages will not appear when the computer is restarted after the removal instructions have been fully completed. The messages displayed may be similar to the following:

Title: [FILE PATH]
Message body: Windows cannot find [FILE NAME]. Make sure you typed the name correctly, and then try again. To search for a file, click the Start button, and then click Search.


4. To delete the value from the registry
Important: Symantec strongly recommends that you back up the registry before making any changes to it. Incorrect changes to the registry can result in permanent data loss or corrupted files. Modify the specified subkeys only. For instructions refer to the document: How to make a backup of the Windows registry.
  1. Click Start > Run.
  2. Type regedit
  3. Click OK.

    Note: If the registry editor fails to open the threat may have modified the registry to prevent access to the registry editor. Security Response has developed a tool to resolve this problem. Download and run this tool, and then continue with the removal.

  4. Navigate to the subkey:

    HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Run

  5. In the right pane, delete the value:

    "MovieM" = "%System%\lmovie.exe"

  6. Exit the Registry Editor.
