The recent WannaCry ransomware cyberattack provided another chilling reminder of the potential disruptive power behind the Internet of Things. Even before the WannaCry attack in May 2017, a distributed-denial-of-service (DDoS) attack on a domain name server provider, Dyn, Inc., took place in October 2016, pushing many popular internet services offline for hours.

It illustrated that hackers can now target vulnerable low-hanging fruit and turn it into a super botnet to carry out the DDoS attack. One takeaway from the Dyn attack is that the exponential growth of devices coming online, some 5.5 million per day according to Gartner, creates an unparalleled ecosystem for malevolent actors to find and weaponize the Internet of Things (IoT).
