Technical Information
To ensure autorun and distribution:
Modifies the following registry keys:
- [<HKLM>\SOFTWARE\Microsoft\Windows\CurrentVersion\Run] '*WinMediaManager0' = '"%ALLUSERSPROFILE%\WinMediaManager0\taskeng.exe"'
- [<HKLM>\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\mmc.exe] 'Debugger' = 'wuauclt.exe'
- [<HKLM>\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\Firewall.cpl] 'Debugger' = 'wuauclt.exe'
Changes the following executable system files:
- <SYSTEM32>\mmc.exe.rz3b9m
- <SYSTEM32>\Firewall.cpl.9724E
Malicious functions:
To bypass firewall, removes or modifies the following registry keys:
- [<HKLM>\SYSTEM\ControlSet001\Services\SharedAccess\Parameters\FirewallPolicy\StandardProfile] 'EnableFirewall' = '00000000'
- [<HKLM>\SYSTEM\ControlSet001\Services\SharedAccess\Parameters\FirewallPolicy\StandardProfile] 'DoNotAllowExceptions' = '00000000'
- [<HKLM>\SYSTEM\ControlSet001\Services\SharedAccess\Parameters\FirewallPolicy\DomainProfile] 'EnableFirewall' = '00000000'
- [<HKLM>\SYSTEM\ControlSet001\Services\SharedAccess\Parameters\FirewallPolicy\DomainProfile] 'DoNotAllowExceptions' = '00000000'
To complicate detection of its presence in the operating system,
forces the system hide from view:
- hidden files
Executes the following:
- '<SYSTEM32>\netsh.exe' firewall set opmode mode=disable profile=all
- '<SYSTEM32>\sc.exe' config SharedAccess start= disabled
Modifies file system :
Creates the following files:
- <SYSTEM32>\mmc.exe:Zone.Identifier
- %ALLUSERSPROFILE%\WinMediaManager0\vboxservice.exe
- %APPDATA%\stereoscope.sb
- <SYSTEM32>\firewall.cpl:Zone.Identifier
Sets the 'hidden' attribute to the following files:
- %ALLUSERSPROFILE%\WinMediaManager0\vboxservice.exe
Deletes the following files:
- <SYSTEM32>\xRZRzsZFfNtGOfj
- <SYSTEM32>\wokI[QYbmXTNCndHEQDSx
