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. 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. Those Apple devices aside, Oligo’s chief technology officer and cofounder, Gal Elbaz, estimates that potentially vulnerable third-party AirPlay-enabled devices number in the tens of millions. Apple tells WIRED that it has also created patches that are available for impacted third-party devices. Apple adds that while there is potentially some user data on devices like TVs and speakers, it is typically very limited.
