This module will bypass Windows UAC by utilizing the trusted publisher
certificate through process injection. It will spawn a second shell that
has the UAC flag turned off. This module uses the Reflective DLL Injection
technique to drop only the DLL payload binary instead of three seperate
binaries in the standard technique. However, it requires the correct
architecture to be selected, (use x64 for SYSWOW64 systems also).
