            "description": "The defender correlates a supervised-device or managed-app request to a legitimate web platform with a subsequent connection to a newly derived destination that is not part of the expected service interaction. Because iOS has weaker app-level telemetry, the strongest signal is a network-level sequence where a request to a known public platform is immediately followed by a connection to a different domain or IP, particularly when the device is locked, no recent user interaction occurred, and the bundle is not expected to interact with such downstream infrastructure.",
