Installation
This Trojan Spy drops the following files:
- %User Temp%\{7 random characters 1}.tmp ← deleted afterwards
- %User Temp%\{7 random characters 2}.tmp ← deleted afterwards
- %User Temp%\{7 random characters 3}.tmp ← deleted after afterwards
- %User Temp%\gvffc.ytu ← shellcode that will be decrypted and injected to vpxpxta.exe
- %User Temp%\rdsdqatpbhs.z ← shellcode that will be decrypted and injected to vpxpxta.exe
- %User Temp%\vpxpxta.exe

- %Application Data%\{Random Characters Derived From Username and "/je14/"}\{Random Characters}log.ini ← contains gathered data
- %Application Data%\{Random Characters Derived From Username and "/je14/"}\{Random Characters}logrc.ini ← contains gathered data
(Note: %User Temp% is the current user's Temp folder, which is usually C:\Documents and Settings\{user name}\Local Settings\Temp on Windows 2000(32-bit), XP, and Server 2003(32-bit), or C:\Users\{user name}\AppData\Local\Temp on Windows Vista, 7, 8, 8.1, 2008(64-bit), 2012(64-bit) and 10(64-bit).. %Program Files% is the default Program Files folder, usually C:\Program Files in Windows 2000(32-bit), Server 2003(32-bit), XP, Vista(64-bit), 7, 8, 8.1, 2008(64-bit), 2012(64-bit) and 10(64-bit) , or C:\Program Files (x86) in Windows XP(64-bit), Vista(64-bit), 7(64-bit), 8(64-bit), 8.1(64-bit), 2008(64-bit), 2012(64-bit) and 10(64-bit).. %Application Data% is the current user's Application Data folder, which is usually C:\Documents and Settings\{user name}\Application Data on Windows 2000(32-bit), XP, and Server 2003(32-bit), or C:\Users\{user name}\AppData\Roaming on Windows Vista, 7, 8, 8.1, 2008(64-bit), 2012(64-bit) and 10(64-bit).)
It adds the following processes:
- %User Temp%\vpxpxta.exe "%User Temp%\rdsdqatpbhs.z"
- %User Temp%\vpxpxta.exe
- %System%\cmd.exe /c copy "%User Temp%\vpxpxta.exe" "%Program Files%\{Random Characters}\{Random Characters}.exe" /V
- %System%\cmd.exe /c del "%User Temp%\vpxpxta.exe"
(Note: %User Temp% is the current user's Temp folder, which is usually C:\Documents and Settings\{user name}\Local Settings\Temp on Windows 2000(32-bit), XP, and Server 2003(32-bit), or C:\Users\{user name}\AppData\Local\Temp on Windows Vista, 7, 8, 8.1, 2008(64-bit), 2012(64-bit) and 10(64-bit).. %Program Files% is the default Program Files folder, usually C:\Program Files in Windows 2000(32-bit), Server 2003(32-bit), XP, Vista(64-bit), 7, 8, 8.1, 2008(64-bit), 2012(64-bit) and 10(64-bit) , or C:\Program Files (x86) in Windows XP(64-bit), Vista(64-bit), 7(64-bit), 8(64-bit), 8.1(64-bit), 2008(64-bit), 2012(64-bit) and 10(64-bit).)
It creates the following folders:
- %Program Files%\{Random Characters}
- %Application Data%\{Random Characters Derived From Username and "/je14/"}
(Note: %Program Files% is the default Program Files folder, usually C:\Program Files in Windows 2000(32-bit), Server 2003(32-bit), XP, Vista(64-bit), 7, 8, 8.1, 2008(64-bit), 2012(64-bit) and 10(64-bit) , or C:\Program Files (x86) in Windows XP(64-bit), Vista(64-bit), 7(64-bit), 8(64-bit), 8.1(64-bit), 2008(64-bit), 2012(64-bit) and 10(64-bit).. %Application Data% is the current user's Application Data folder, which is usually C:\Documents and Settings\{user name}\Application Data on Windows 2000(32-bit), XP, and Server 2003(32-bit), or C:\Users\{user name}\AppData\Roaming on Windows Vista, 7, 8, 8.1, 2008(64-bit), 2012(64-bit) and 10(64-bit).)

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.XXPE50FSX038
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
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
- {Random Characters} = %Program Files%\{Random Characters}\{Random Characters}.exe
- {Random Characters} = %Program Files%\{Random Characters}\{Random Characters}.exe
Step 6
Search and delete these files
- %User Temp%\{7 random characters}.tmp
- %User Temp%\{7 random characters 2}.tmp
- %User Temp%\{7 random characters 3}.tmp
- %User Temp%\gvffc.ytu
- %User Temp%\rdsdqatpbhs.z
- %User Temp%\vpxpxta.exe
- %Program Files%\{Random Characters}\{Random Characters}.exe
- %Application Data%\{Random Characters Derived From Username and /je14/}\{Random Characters}log.ini
- %Application Data%\{Random Characters Derived From Username and /je14/}\{Random Characters}logrc.ini
Step 7
Search and delete these folders
- %Program Files%\{Random Characters}
- %Application Data%\{Random Characters Derived From Username and /je14/}
Step 8
Restart in normal mode and scan your computer with your Trend Micro product for files detected as TrojanSpy.Win32.FORMBOOK.SHPM. 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 this Knowledge Base page for more information.
