W32.Kelvir.W

Risk Level 2: Low

Discovered:
April 15, 2005
Updated:
February 13, 2007 12:37:07 PM
Also Known As:
Win32.Kelvir.I [Computer Assoc, IM-Worm.Win32.Kelvir.ar [Kaspe, W32/Kelvir.worm.gen [McAfee], W32/Kelvir-Gen [Sophos], WORM_KELVIR.P [Trend Micro]
Type:
Worm
Systems Affected:
Windows 2000, Windows 95, Windows 98, Windows Me, Windows NT, Windows Server 2003, Windows XP

When W32.Kelvir.W is executed, it performs the following actions:

  1. Sends the following message to all the MSN Messenger contacts on the compromised computer:

    Message: its you!
    http: //www.[domain removed].us/gallery/pictures.php?email=

    Note: A recipient must click on the link, download the file, and then execute pictures.php?email. This file is a self-extracting RAR file.

  2. Drops the following files:

    • %ProgramFiles%\ACS-Style\rxBot.exe (A variant of W32.Spybot.Worm)
    • %ProgramFiles%\ACS-Style\acs.exe (A worm component that sends the above mentioned message to all the MSN Messenger contacts on the compromised computer)

      Note: %ProgramFiles% is a variable that refers to the program files folder. By default, this is C:\Program Files.

  3. Adds the value:

    "C%%Program Files%ACS-Style" = "%ProgramFiles%\ACS-Style"

    to the registry subkey:

    HKEY_CURRENT_USER\Software\WinRAR SFX

  4. Drops the W32.Spybot.Worm variant through the file rxBot.exe. This variant:

    • May be remotely controlled, via Internet Relay Chat (IRC) channels.
    • Includes Distributed Denial of Service (DDoS) and back door capabilities.
    • The W32.Spybot.Worm variant attempts to steal confidential information from the compromised system and attempts to exploit multiple vulnerabilities to spread.

  5. Creates the following copy of itself when rxBot.exe runs:

    %system%\winsystem32xp.exe

    Note: %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).

  6. Adds the value:

    "Microsoft Xp System loader" = "winsystem32xp.exe"

    to the registry subkeys:

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\
    RunServices
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\OLE
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa
    HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
    HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\
    RunServices
    HKEY_CURRENT_USER\Software\Microsoft\OLE
    HKEY_CURRENT_USER\SYSTEM\CurrentControlSet\Control\Lsa

  7. Attempts to open a back door by connecting to an IRC channel on TCP port 2442 on the server 66.111.56.101. The worm then waits and listens for commands that allow the attacker to perform the following actions:

    • Download and execute files.
    • List, stop, and start processes.
    • Launch Denial of Service (DoS) attacks.
    • Steal system information and passwords and send it to the attacker.
    • Redirect ports.
    • Send files over IRC.
    • Send email using its own SMTP engine.
    • Start a local Web, FTP, or ident server.
    • Log keystrokes to file.
    • Try to break into network shares and copy itself to it.
    • Scan the network for vulnerable hosts.

  8. Spreads by exploiting the following vulnerabilities:

  9. Attempts to spread to network shares that make use of weak passwords.

  10. Disables the following processes, some of which may be security related:

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.
