What it detects
This rule identifies Windows process creation where wscript.exe is the parent, launching cmd.exe or PowerShell based on an associated execution chain. It matches a parent command line containing a local Temp path and a zip filename with an update-related .js script, along with common browser process names. This matters because it reflects malware-style staging where a script is launched from a packaged download and then hands off to command-line tooling. Telemetry required is Windows process creation events including parent image/command line and the child image.
