Arrival Details

This worm arrives on a system as a file dropped by other malware or as a file downloaded unknowingly by users when visiting malicious sites.

Autostart Technique

This worm registers as a system service to ensure its automatic execution at every system startup by adding the following registry keys:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\
Services\vds2

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\
Services\VMAuthd Service

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\
Services\VMnet DHCP

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\
Services\VMwareNATService

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\
Services\vmount3

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\
Services\Installer information

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\
Services\lanmanworkstation2

Other System Modifications

This worm deletes the following files:

  • %System%\drivers\HookHelp.sys
  • %System%\drivers\HookSys.sys
  • %System%\drivers\RsNTGdi.sys
  • %System%\drivers\HookCont.sys
  • %System%\drivers\safeboxkrnl.sys

Dropping Routine

This worm drops the following files:

  • %Windows%\ctfmon.exe
  • %Windows%\inetinfo.exe
  • %Windows%\winlogon.exe
  • %System%\TIMPlatform.exe
  • %Windows%\inf\realplayer.exe
  • %Program Files%\INTERN~1\iedws.exe
