Hi. Many of those appliances are marketed as being able to make your files available to you, even when you're not at home. (Music, photos etc.) They come with crude mobile app's (among other things, to monetize the user) and the security/authentication varies from so so, to nil. (Guess what most users opt for, because "it's difficult" to do it securely.) Remember, we're talking about Joe Public, not a sysadmin! That, and they either punch holes in the router using UPnP, or people (I know one) place them in a DMZ, again, because it's easy, and "it just works." What else is then exposed, who knows? The rest as they say, one day will be history. Using Shodan, it is not difficult to find admin login pages on the public internet, for all sorts of bits of equipment and other gadgetry. Take care.
