To complicate detection of its presence in the operating system,
forces the system hide from view:
- hidden files
Creates and executes the following:
- '%APPDATA%\WUD32Host.exe'
- '%WINDIR%\audio32hd.exe'
Executes the following:
- '<SYSTEM32>\netsh.exe' Firewall set opmode disable
Modifies file system :
Creates the following files:
- %APPDATA%\WUD32Host.exe
- %WINDIR%\audio32hd.exe
Sets the 'hidden' attribute to the following files:
- %APPDATA%\WUD32Host.exe
- %WINDIR%\audio32hd.exe
