Arrival Details

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

Installation

This Trojan adds the following processes:

  • "{malware file name}.exe" /1
  • %Windows%\Microsoft.NET\Framework64\v2.0.50727\installutil.exe /name=LTService /account=localsystem %Windows%\LTSVC\LTSVC.exe
  • "%Windows%\LTSVC\LTSVC.exe" -sLTService
  • %Windows%\LTSVC\LTTray.exe

(Note: %Windows% is the Windows folder, where it usually is C:\Windows on all Windows operating system versions.)

It creates the following folders:

  • %Windows%\LTSvc\Plugins
  • %Windows%\LTSvc
  • %All Users Profile%\Labtech
  • %All Users Profile%\Labtech\Tickets
  • %Windows%\Temp\LTCache
  • %All Users Profile%\Labtech\Responses
  • %All Users Profile%\Labtech\Inbox

(Note: %Windows% is the Windows folder, where it usually is C:\Windows on all Windows operating system versions.. %All Users Profile% is the common user's profile folder, which is usually C:\Documents and Settings\All Users on Windows 2000(32-bit), XP, and Server 2003(32-bit), or C:\ProgramData on Windows Vista, 7, 8, 8.1, 2008(64-bit), 2012(64-bit) and 10(64-bit). )

Autostart Technique

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

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\
services\LTService
ImagePath = "%Windows%\LTSVC\LTSVC.exe -sLTService"

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\
Services\LTService
ImagePath = "%Windows%\LTSVC\LTSVC.exe"

Other System Modifications

This Trojan modifies the following file(s):

  • %Windows%\Temp\Cab7AAB.tmp
  • %Windows%\Temp\Cab9F5C.tmp
  • %Windows%\Temp\TarA7D7.tmp
  • %Windows%\Temp\CabA7D6.tmp
  • %Windows%\Temp\CabBDF7.tmp
  • %Windows%\Temp\TarBDF8.tmp
  • %Windows%\Temp\Tar9F5D.tmp
  • %Windows%\Temp\Tar7AAC.tmp

(Note: %Windows% is the Windows folder, where it usually is C:\Windows on all Windows operating system versions.)
