This rule detects PowerShell commands indicative of reflective code loading, specifically looking for the use of 'Assembly' and 'Load' or 'GetType' and 'Invoke' within PowerShell command arguments. It filters out common noise associated with legitimate PowerShell operations like PSGet, Cursor, and internal Microsoft PowerShell modules to reduce false positives.
