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.)

- %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

Step 1
Before doing any scans, Windows 7, Windows 8, Windows 8.1, and Windows 10 users must disable System Restore to allow full scanning of their computers.
Step 2
Identify and terminate files detected as Trojan.Win32.FORTNET.A
- Windows Task Manager may not display all running processes. In this case, please use a third-party process viewer, preferably Process Explorer, to terminate the malware/grayware/spyware file. You may download the said tool here.
- If the detected file is displayed in either Windows Task Manager or Process Explorer but you cannot delete it, restart your computer in safe mode. To do this, refer to this link for the complete steps.
- If the detected file is not displayed in either Windows Task Manager or Process Explorer, continue doing the next steps.
Step 3
Delete this registry key
Important: Editing the Windows Registry incorrectly can lead to irreversible system malfunction. Please do this step only if you know how or you can ask assistance from your system administrator. Else, check this Microsoft article first before modifying your computer's registry.

Step 7
Scan your computer with your Trend Micro product to delete files detected as Trojan.Win32.FORTNET.A. If the detected files have already been cleaned, deleted, or quarantined by your Trend Micro product, no further step is required. You may opt to simply delete the quarantined files. Please check the following Trend Micro Support pages for more information:
Step 8
Restore deleted/modified files and/or registry entries from backup
*Note: Only Microsoft-related files/keys/values will be restored. If this malware/grayware also deleted registry keys/values related to programs that are not from Microsoft, please reinstall those programs on your computer.
