Vendor Fixes Vulnerabilities in Wireless Traffic Sensors

Sensys Networks, a company that provides integrated wireless traffic data systems, announced last week the availability of software updates that address security issues identified last year.
In April, IOActive Labs CTO Cesar Cerrudo revealed the existence of several vulnerabilitiesin the sensor devices used by the traffic control systems installed in various cities across the United States, Canada, the United Kingdom, France, Australia and China. He conducted real-world tests in various U.S. cities and even simulated an attack launched from a drone.
"By exploiting the vulnerabilities I found, an attacker could cause traffic jams and problems at intersections, freeways, highways, etc," the researcher explained back in April. "It's possible to make traffic lights (depending on the configuration) stay green more or less time, stay red and not change to green, or flash. It’s also possible to cause electronic signs to display incorrect speed limits and instructions and to make ramp meters allow cars on the freeway faster or slower than needed."
