Apple’s AirPlay feature enables iPhones and Macbooks to seamlessly play music or show photos and videos on other Apple devices or third-party speakers and TVs that integrate the protocol. Now newly uncovered security flaws in AirPlay mean that those same wireless connections could allow hackers to move within a network just as easily, spreading malicious code from one infected device to another. Apple products are known for regularly receiving fixes, but given how rarely some smart-home devices are patched, it’s likely that these wirelessly enabled footholds for malware, across many of the hundreds of models of AirPlay-enabled devices, will persist for years to come.
