Cyber security vulnerabilities in traffic lights, including some in Chicago

A new report identifies the city of Chicago among the U.S. locations utilizing Sensys Networks wireless technology in traffic light systems recently identified as vulnerable to cyber attacks.

The findings of a NBC 5 Chicago investigation released on Tuesday found that Sensys Networks systems are used in 10 countries, and 45 U.S. states — including Illinois. A Chicago Department of Transportation spokesperson told NBC reporters that only 12 intersections in Chicago utilize Sensys Networks wireless technology, but could not say whether a security patch issued by the company had been applied to the affected traffic lights.
