The Pew Research Centerhas released The Internet of Things Connectivity Binge: What Are the Implications? .
Here's an excerpt:
Researchers have been showing how easy it is to hack cars, voting machines and power plants. They have demonstrated ransomware exploits against home thermostats and exposed vulnerabilities in implanted heart pacemakers. In one paper, "IoT Goes Nuclear," analysts showed how a flaw in the design of smart lightbulbs could be used for a "bricking attack" that kills all of a city's traffic lights. . . .
Thus, the question: Could security vulnerabilities that become evident as the IoT rolls out prompt people, businesses and government to avoid or withdraw from certain online connectivity options? In summer 2016, Pew Research Center and Elon University’s Imagining the Internet Center conducted a large canvassing of technologists, scholars, practitioners, strategic thinkers and other leaders, asking them to react to this framing of the issue.
