(Note: %System% is the Windows system folder, where it usually is C:\Windows\System32 on all Windows operating system versions.. %AppDataLocal% is the Local Application Data folder, which is usually C:\Documents and Settings\{user name}\Local Settings\Application Data on Windows 2000(32-bit), XP, and Server 2003(32-bit), or C:\Users\{user name}\AppData\Local on Windows Vista, 7, 8, 8.1, 2008(64-bit), 2012(64-bit) and 10(64-bit).)
It adds the following processes:
- {Malware Path}\{Malware File Name}.exe --{8 random characters}
- With Admin rights:
- %System%\{String1}{String2}.exe
- %System%\{String1}{String2}.exe--{8 random characters}
- Without Admin rights:
- %AppDataLocal%\{String1}{String2}\{String1}{String2}.exe
- %AppDataLocal%\{String1}{String2}\{String1}{String2}.exe --{8 random characters}
(Note: %System% is the Windows system folder, where it usually is C:\Windows\System32 on all Windows operating system versions.. %AppDataLocal% is the Local Application Data folder, which is usually C:\Documents and Settings\{user name}\Local Settings\Application Data on Windows 2000(32-bit), XP, and Server 2003(32-bit), or C:\Users\{user name}\AppData\Local on Windows Vista, 7, 8, 8.1, 2008(64-bit), 2012(64-bit) and 10(64-bit).)
It creates the following folders:

(Note: %AppDataLocal% is the Local Application Data folder, which is usually C:\Documents and Settings\{user name}\Local Settings\Application Data on Windows 2000(32-bit), XP, and Server 2003(32-bit), or C:\Users\{user name}\AppData\Local on Windows Vista, 7, 8, 8.1, 2008(64-bit), 2012(64-bit) and 10(64-bit).)
It adds the following mutexes to ensure that only one of its copies runs at any one time:
- Global\I{Volume Serial Number}
- Global\M{Volume Serial Number}
Autostart Technique
This Trojan Spy 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\{String1}{String2}
ImagePath = %System%\{String1}{String2}.exe
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\
Services\{String1}{String2}
ImagePath = %System%\{String1}{String2}.exe
It adds the following registry entries to enable its automatic execution at every system startup:
HKEY_CURRENT_USER\Software\Microsoft\
Windows\CurrentVersion\Run
{String1}{String2} = %AppDataLocal%\{String1}{String2}\{String1]{String2}.exe"
Information Theft
This Trojan Spy gathers the following data:

SOLUTION
Step 1
Trend Micro Predictive Machine Learning detects and blocks malware at the first sign of its existence, before it executes on your system. When enabled, your Trend Micro product detects this malware under the following machine learning name:
- Troj.Win32.TRX.XXPE50FFF030
Step 2
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 3
Note that not all files, folders, and registry keys and entries are installed on your computer during this malware's/spyware's/grayware's execution. This may be due to incomplete installation or other operating system conditions. If you do not find the same files/folders/registry information, please proceed to the next step.
Step 4
Restart in Safe Mode
Step 5
Search and delete these files
- %System%\{String1}{String2}.exe
- %AppDataLocal%\{String1}{String2}\{String1}{String2}.exe
Step 6
Search and delete these folders
- %AppDataLocal%\{String1}{String2}
Step 7
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.
- In HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\{String1}{String2}
- ImagePath = %System%\{String1}{String2}.exe
- ImagePath = %System%\{String1}{String2}.exe
- In HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\{String1}{String2}
- ImagePath = %System%\{String1}{String2}.exe
- ImagePath = %System%\{String1}{String2}.exe
Step 8
Delete this registry value
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.
- In HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
- {String1}{String2} = %AppDataLocal%\{String1}{String2}\{String1]{String2}.exe
- {String1}{String2} = %AppDataLocal%\{String1}{String2}\{String1]{String2}.exe
Step 9
Restart in normal mode and scan your computer with your Trend Micro product for files detected as TrojanSpy.Win32.EMOTET.THEHAI. 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.
