W32.Spybot.KAI

1. Checks for the presence of a debugger and terminates itself if one is found.
   
   
2. Copies itself as the following:
   
   
   • %System%\antivirus.exe.
   • %System%\kazaabackupfiles\Adobe Acrobat crack works Great crack all versions No cd and Cd keygen.exe
   • %System%\kazaabackupfiles\Adobe all software crack that works Great keygen does all versions.exe
   • %System%\kazaabackupfiles\Adobe Photoshop crack does any version works Great No cd and keygen.exe
   • %System%\kazaabackupfiles\McAfee VirusScan crack works Great does all versions.exe
   • %System%\kazaabackupfiles\Microsoft Frontpage Crack for all versions and Keygen.exe
   • %System%\kazaabackupfiles\Microsoft Money Crack for all versions and Keygen.exe
   • %System%\kazaabackupfiles\Microsoft Office crack does every version 2003 XP etc works Great.exe
   • %System%\kazaabackupfiles\Microsoft Windows Crack and keygen for every os version XP 2000 98 95.exe
   • %System%\kazaabackupfiles\Nero 6 crack No cd and Cd keygen works on all other nero versions.exe
   • %System%\kazaabackupfiles\Norton SystemWorks crack works Great keygen does all versions.exe
   • %System%\kazaabackupfiles\PC-cillin crack that works Great No cd and keygen cracks all PC cillin software.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).
     
     
3. Creates the file %System%\SVKP.sys
   
   
4. Adds the value:
   
   "antivirus32" = "antivirus.exe"
   
   to the registry keys:
   
   HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
   HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Runonce
   HKEY_USERS\.Default\Software\Microsoft\Windows\CurrentVersion\Runonce
   
   so that W32.Spybot.KAI runs every time Windows starts.
   
   
5. Creates the following registry entries:
   
   HKEY_CURRENT_USER\Software\KAZAA\local content\Dir0="012345:%System%\kazaabackupfiles
   HKEY_USERS\.Default\Software\KAZAA\local content\Dir0="012345:%System%\kazaabackupfiles
   
   This will ensure that the worm propagates through Kazaa.
   
   
6. Adds the registry keys:
   
   HKEY_LOCAL_MACHINE\System\CurrentControlSe\ENUM\ROOT\LEGACY_SVKP
   HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\SVKP

   "Enable DCOM" = "N"
   "Enable Remote Connect" = "N"
   
   to the following registry keys:
   
   HKEY_LOCAL_MACHINE\Software\Microsoft\OLE
   HKEY_LOCAL_MACHINE\Software\Microsoft\OLE
   
   
8. Opens a back door by connecting to an IRC channel and listens for commands from the remote attacker.
   

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.
