Have you seen "Person of Interest", where one of the protagonists constantly accesses and controls devices connected to the internet?

Much of that is preposterous and oversimplified fiction, but Shodan demonstrates that it's not as far-fetched as it appears. Many of the connected devices have default passwords still in place.
