What it detects

This rule detects trusted Windows utilities loading propsys or batmeter DLLs from ProgramData or the Public directory. The Dohdoor campaign sideloads its payload through living-off-the-land binaries such as OpenWith and mblctr running from unusual paths. A signed utility loading a system-named DLL from a writable directory is a strong sideloading indicator.
