What it detects

This rule detects osascript invoking an eppc URL, matching the Bad Apples technique that weaponizes Remote Apple Events over TCP 3031 for lateral movement across macOS hosts. Sending AppleScript to a remote host via the eppc scheme lets an operator execute code on another Mac using native primitives. Such cross-host osascript activity is rarely benign and indicates hands-on movement.
