What it detects
This rule flags Windows Installer activity where the MsiInstaller provider is involved and the event contains a URL-like string ("//"). Remote MSI installations can be used to deliver and execute additional payloads or perform stealthy software deployment. It relies on Windows application logs with EventID 1040 or 1042 and the presence of web-style URI content in the recorded event data.
