Technical Information
To ensure autorun and distribution:
Modifies the following registry keys:
- [<HKCU>\Software\Microsoft\Windows\CurrentVersion\Run] 'DEEP' = '"%APPDATA%\DEEP.scr"'
Creates the following files on removable media:
- <Drive name for removable media>:\evmu.pif
- <Drive name for removable media>:\autorun.inf
Malicious functions:
To bypass firewall, removes or modifies the following registry keys:
- [<HKLM>\SYSTEM\ControlSet001\Services\SharedAccess\Parameters\FirewallPolicy\StandardProfile] 'DisableNotifications' = '00000001'
- [<HKLM>\SYSTEM\ControlSet001\Services\SharedAccess\Parameters\FirewallPolicy\StandardProfile\AuthorizedApplications\List] '<Full path to virus>' = '<Full path to virus>:*:Enabled:Windows Messanger'
- [<HKLM>\SYSTEM\ControlSet001\Services\SharedAccess\Parameters\FirewallPolicy\StandardProfile\AuthorizedApplications\List] '%APPDATA%\isa.exe' = '%APPDATA%\isa.exe:*:Enabled:Windows Messanger'
- [<HKLM>\SYSTEM\ControlSet001\Services\SharedAccess\Parameters\FirewallPolicy\StandardProfile\AuthorizedApplications\List] '<Full path to virus>' = '<Full path to virus>:*:Enabled:ipsec'
- [<HKLM>\SYSTEM\ControlSet001\Services\SharedAccess\Parameters\FirewallPolicy\StandardProfile] 'EnableFirewall' = '00000000'
- [<HKLM>\SYSTEM\ControlSet001\Services\SharedAccess\Parameters\FirewallPolicy\StandardProfile] 'DoNotAllowExceptions' = '00000000'
To complicate detection of its presence in the operating system,
forces the system hide from view:
- hidden files
blocks execution of the following system utilities:
- Windows Task Manager (Taskmgr)
- Registry Editor (RegEdit)
blocks the following features:
- User Account Control (UAC)
- Windows Security Center
Executes the following:
- <SYSTEM32>\reg.exe ADD HKLM\System\CurrentControlSet\Services\SharedAccess\Parameters\FirewallPolicy\StandardProfile\AuthorizedApplications\List /v "%APPDATA%\isa.exe" /t REG_SZ /d "%APPDATA%\isa.exe:*:Enabled:Windows Messanger" /f
- <SYSTEM32>\reg.exe ADD HKLM\System\CurrentControlSet\Services\SharedAccess\Parameters\FirewallPolicy\StandardProfile\AuthorizedApplications\List /v "<Full path to virus>" /t REG_SZ /d "<Full path to virus>:*:Enabled:Windows Messanger" /f
- <SYSTEM32>\reg.exe ADD HKLM\System\CurrentControlSet\Services\SharedAccess\Parameters\FirewallPolicy\StandardProfile /v "DoNotAllowExceptions" /t REG_DWORD /d "0" /f
Injects code into
the following system processes:
- <SYSTEM32>\cmd.exe
a large number of user processes.
Modifies file system :
Creates the following files:
- %APPDATA%\Winzip
- C:\autorun.inf
- C:\rjdxh.exe
- %APPDATA%\DEEP.scr
- %TEMP%\pkpexk.exe
- %APPDATA%\isa.exe
Sets the 'hidden' attribute to the following files:
- <Drive name for removable media>:\autorun.inf
- <Drive name for removable media>:\evmu.pif
- C:\autorun.inf
- C:\rjdxh.exe
Deletes the following files:
- %TEMP%\pkpexk.exe
