A Mac usually has wireless interfaces such as WLAN or Bluetooth, which are also used by many services and activated accordingly. WLAN, for example, can be used to exchange files directly between Apple devices (AirDrop). Furthermore, the WLAN and Bluetooth functions can be used to synchronise macOS and iOS devices (Continuity). AirPlay, meanwhile, makes it possible to send video and audio data to a compatible playback device. Attackers could attempt to misuse these wireless interfaces for attacks in order to intercept confidential information between Macs, iPhones, iPads, and other devices, or to compromise them in other ways.
