Nissan Motor Co. disabled a mobile application for controlling its Leaf electric car following a security researcher demonstrated how hackers could access temperature controls and other functions from across continents.
Japan’s second-largest automaker made the app unavailable after Australian researcher Troy Hunt demonstrated the capability to hack into a friend’s Leaf within the U.K. and access information about the battery status and climate controls. Hunt wrote the car’s vehicle identification number, that is visible through the car’s windshield, was the only piece of information needed to undermine the app’s insecure programming.
