Arrival Details
This backdoor arrives as an attachment to the following email messages spammed by other malware/grayware or malicious users:
Installation
This backdoor drops the following copies of itself into the affected system and executes them:
- %User Profile%\SNHYuxinJqE\SNHYuxinJqE\AG6OYFsIwq3.V06yB9
(Note: %User Profile% is the current user's profile folder, which is usually C:\Documents and Settings\{user name} on Windows 2000, XP, and Server 2003, or C:\Users\{user name} on Windows Vista and 7.)
It drops the following files:
- %User Profile%\SNHYuxinJqE\6XPvPI\{Java Installation folder}
- %User Profile%\.oracle_jre_usage\{random number}.timestamp - time usage of oracle
- %User Temp%\hsperfdata_{username}\{random} - contains details of the malware
(Note: %User Profile% is the current user's profile folder, which is usually C:\Documents and Settings\{user name} on Windows 2000, XP, and Server 2003, or C:\Users\{user name} on Windows Vista and 7.. %User Temp% is the user's temporary folder, where it usually is C:\Documents and Settings\{user name}\Local Settings\Temp on Windows 2000, Windows Server 2003, and Windows XP (32- and 64-bit); C:\Users\{user name}\AppData\Local\Temp on Windows Vista (32- and 64-bit), Windows 7 (32- and 64-bit), Windows 8 (32- and 64-bit), Windows 8.1 (32- and 64-bit), Windows Server 2008, and Windows Server 2012.)
It drops and executes the following files:
- %User Temp%\WindowsCleanDirectory{random}.reg - contains the registry modifications
(Note: %User Temp% is the user's temporary folder, where it usually is C:\Documents and Settings\{user name}\Local Settings\Temp on Windows 2000, Windows Server 2003, and Windows XP (32- and 64-bit); C:\Users\{user name}\AppData\Local\Temp on Windows Vista (32- and 64-bit), Windows 7 (32- and 64-bit), Windows 8 (32- and 64-bit), Windows 8.1 (32- and 64-bit), Windows Server 2008, and Windows Server 2012.)
It creates the following folders:
- %User Profile%\SNHYuxinJqE\
- %User Profile%\SNHYuxinJqE\6XPvPI\
- %User Profile%\SNHYuxinJqE\SNHYuxinJqE\
- %User Profile%\.oracle_jre_usage\
- %User Temp%\hsperfdata_{username}\
- %User Profile%\SNHYuxinJqE\KVWU6hLOLrp
(Note: %User Profile% is the current user's profile folder, which is usually C:\Documents and Settings\{user name} on Windows 2000, XP, and Server 2003, or C:\Users\{user name} on Windows Vista and 7.. %User Temp% is the user's temporary folder, where it usually is C:\Documents and Settings\{user name}\Local Settings\Temp on Windows 2000, Windows Server 2003, and Windows XP (32- and 64-bit); C:\Users\{user name}\AppData\Local\Temp on Windows Vista (32- and 64-bit), Windows 7 (32- and 64-bit), Windows 8 (32- and 64-bit), Windows 8.1 (32- and 64-bit), Windows Server 2008, and Windows Server 2012.)

Step 1
Before doing any scans, Windows XP, Windows Vista, and Windows 7 users must disable System Restore to allow full scanning of their computers.
Step 2
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 3
Restart in Safe Mode
Step 4
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
- 6kdAnpEBCxX = "%User Profile%\SNHYuxinJqE\6XPvPI\bin\javaw.exe" -jar "%User Profile%\SNHYuxinJqE\SNHYuxinJqE\AG6OYFsIwq3.V06yB9"
- 6kdAnpEBCxX = "%User Profile%\SNHYuxinJqE\6XPvPI\bin\javaw.exe" -jar "%User Profile%\SNHYuxinJqE\SNHYuxinJqE\AG6OYFsIwq3.V06yB9"
- In HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\{Application}
- debugger = svchost.exe
- debugger = svchost.exe
Step 5
Restore this modified 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_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System
- From: ConsentPromptBehaviorAdmin = 1
To: ConsentPromptBehaviorAdmin = 0
- From: ConsentPromptBehaviorAdmin = 1
- In HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System
- From: ConsentPromptBehaviorUser = 1

Step 6
Search and delete this file
- %User Profile%\SNHYuxinJqE\6XPvPI\{Java Installation folder}
- %User Profile%\.oracle_jre_usage\{random number}.timestamp
- %User Temp%\hsperfdata_{username}\{random}
- %User Profile%\SNHYuxinJqE\SNHYuxinJqE\AG6OYFsIwq3.V06yB9
- %User Temp%\WindowsCleanDirectory{random}.reg
Step 7
Search and delete these folders
- %User Profile%\SNHYuxinJqE\
- %User Profile%\SNHYuxinJqE\6XPvPI\
- %User Profile%\SNHYuxinJqE\SNHYuxinJqE\
- %User Profile%\.oracle_jre_usage\
- %User Temp%\hsperfdata_{username}\
- %User Profile%\SNHYuxinJqE\KVWU6hLOLrp
Step 8
Restart in normal mode and scan your computer with your Trend Micro product for files detected as JAVA_ADWIND.JEJOSA. 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.
