What it detects

This rule detects msiexec.exe installing a package directly from an http or https URL in quiet mode, a NetSupport RAT delivery vector in the ClickFix campaign. The loaders invoked msiexec with a remote URL and the /qn switch to silently install the RAT from attacker infrastructure. Remote quiet MSI installation is a LOLBin abuse pattern used to bypass download controls.
