What it detects

This rule detects a PowerShell download cradle that pipes a fetched script directly into Invoke-Expression using the wget alias. TAG-150 delivers its Griffin20 loader through this ClickFix one-liner that pulls and runs the next stage in memory. In-memory execution of a downloaded script is a strong indicator of fileless staging.
