Even speakers which are known to be the dumbest audiovisual devices are now connected to a network. Although there are other devices where the network connection is used for remote management convenience, networking is crucial to most of these devices. The biggest problem with any network-connected system that has the capabilities of running code is that the system is at risk of being infiltrated via the same network connection and can be used in malicious acts.
