There has been a first wave of devices connected to the Internet: home security systems, security cameras, thermostats, routers and the like. These are the devices that were looped into cyberattack this time around and it is likely a harbinger of things to come. In the not-too-distant future we will have tens of millions of these IoT devices connected to the Internet. Getting them secured should be a high priority for their manufacturers.
And, just for the record, there was this quote from article that was misleading, "Attacks on the companies escalated, [Internet security expert Bruce] Schneier wrote, 'as if the attack were looking for the exact point of failure.' Think of the mighty Maginot Line, tested again and again by the German army in 1940, until it found the weak point and rolled into Paris." The German army did not find a weak point in the Maginot Line, they simply went around it by attacking through Belgium. The maneuver might be called, "isolate and bypass" in military terminology.
