Threats and vulnerabilities associated with The Internet of Things (IoT) are not just focused on wireless cameras, home routers, and DVRs.  There are a myriad of life saving medical devices that communicate via some form of wireless protocol including insulin pumps, pacemakers, and spinal stimulators among others.  These devices, if compromised, can cause problems much larger than a simple DDOS attack.  A compromised medical device can lead to death.  Security must be taken more seriously for these devices in the immediate future.
