Sensys Networks’ traffic sensors communicate wirelessly in clear text and don’t authenticate the data they receive, researcher says. Sensys says it has built-in features in its traffic control equipment that would protect against the download of unauthorized code to its sensors, as well as “attempts to insert false detection data” Cerrudo: “It’s about $100 million worth of equipment that can probably be bricked and cause a traffic jam. You can send fake data that there’s no traffic there” Sensys maintains that it had originally included encryption in the sensors, but ultimately removed the feature after its customers requested it.”]
