We all know that any smart device or computer system can be hacked these days, but if you start actually enumerating all of the vulnerable gadgets, it gets a bit overwhelming. Phones, smart appliances, fitness trackers all connect to an app that stores your personal information. But that’s not all. Researchers at the University of Michigan recently published a paper in which they show how easy it is to hack traffic lights. Wonderful.
With the help of a Michigan road agency, the team hacked actual stoplights in a city in Michigan. They demonstrated that the current system of IP-based networked traffic lights that send and receive information from a central point might save money, but that its use of wireless radios is a vulnerability that’s troublingly easy to exploit.
