During last week's Black Hat computer security conference in Las Vegas, researchers from iSEC Partners demonstrated a vulnerability in 2012 models of Samsung's line of Smart TVs, particularly the ones with that come with cameras designed for teleconferencing. The problem with the Samsung TVs highlights a much larger issue: The number of devices connected to the Internet is growing exponentially, and many of them have little or no security in place. Flaws may be found in almost any application on an Internet-connected platform that, if exploited, could allow access to the entire device, and then the user's full network. Many of these unsecured devices can be found with a simple search. In fact, there's a search engine devoted just to scouring the so-called Internet of things" called Shadon. Playing around with it is an eye-opener. For example, in late July a writer for Forbes discovered an entire home automation product line with Internet-connected features that could be set up without a default password, and were visible to search engines. This would enable a hacker to search and find these systems on the Net, then access them at will. To prove her point, Kashmir Hill breached the home automation systems of random strangers, called them on the phone and demonstrated the vulnerability by turning their lights on and off.
