Installation
This Trojan Spy adds the following folders:
- %AppDataLocal%\{String1}{String2}
(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 drops the following copies of itself into the affected system:
- If sample executed with administrative privileges:
- %System%\{String1}{String2}.exe
- If sample executed without administrative privileges:
- %AppDataLocal%\{String1}{String2}\{String1}{String2}.exe
(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 File Path}\{Malware File Name}.exe --{8 Random Characters}
- If sample executed with administrative privileges:
- %System%\{String1}{String2}.exe
- %System%\{String1}{String2}.exe --{8 Random Characters}
- If sample executed without administrative privileges:
- %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 executes then deletes itself afterward.
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
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:
- Computer Name
- Process SessionId
- OS Version
- Running Processes
- File CRC
- Processor Architecture

- {String1}{String2} = %AppDataLocal%\{String1}{String2}\{String1}{String2}.exe
- {String1}{String2} = %AppDataLocal%\{String1}{String2}\{String1}{String2}.exe
Step 7
Search and delete these files
- %AppDataLocal%\{String1}{String2}\{String1}{String2}.exe
- %System%\{String1}{String2}.exe
Step 8
Search and delete these folders
- %AppDataLocal%\{String1}{String2}
Step 9
Restart in normal mode and scan your computer with your Trend Micro product for files detected as TrojanSpy.Win32.EMOTET.TIABOFGB. 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.
