What it detects

This rule detects tccutil resetting AppleEvents privacy permissions, an automation abuse step performed by the Banshee macOS stealer. Clearing these permissions lets the malware re prompt and gain scripting control over other applications. Detecting it exposes the stealer manipulating privacy controls.
