The current move by auto makers to stuff their vehicles full of networked devices, Bluetooth radios and WiFi connectivity has not gone unnoticed by security researchers. Charlie Miller and Chris Valasek spent months taking apart-literally and figuratively-a Toyota Prius to see what vulnerabilities might lie inside; and they found plenty. Now, another researcher has identified a number of issues with the security of the Tesla S, including its dependence upon a weak one-factor authentication system linked to a mobile app that can unlock the car remotely.
The Tesla S is a high-end, all-electric vehicle that includes a number of interesting features, including a center console touchscreen that controls much of the car's systems. There also is an iPhone app that allows users to control a number of the car's functions, including the door locks, the suspension and braking system and sunroof. Nitesh Dhanjani found that when new owners sign up for an account on the Tesla site, they must create a six-character password. That password is then used to login to the iPhone app.
