A professor at the University of Hiroshima was able to violate a custom-made Toyota Corolla WiFi device with a smartphone application, according to the Japan Times.
In his experiment, Hiroyuki Inoue, associate professor at University Graduate School of Information Sciences, χρησιμοποίησε ένα Toyota Corolla Fielder Hybrid of 2013.
Inoue was able to open and close the car doors, change the speedometer, and block the car's accelerator.
To accomplish this, the professor built a custom WiFi device, which cost about $82. Install the device in the car by connecting it to a door under the steering wheel.
This port exists in the car to allow the engineering maintenance of the car and has a direct connection to the internal CAN bus, where there is all the data from all the electronic devices of the vehicle.
Using his smartphone, Inoue managed to connect with this device and commanded for false indications as well as various other actions.
In addition, Inoue was also able to paralyze the car by sending too many requests at the same time, the equivalent of a DoS (Denial of Service) attack.
Professor's findings raise questions about the security of these types of connection to cars that can connect to the Internet.
Professor Inoue plans to give a lecture on his findings at a three-day cyber security meeting to be held in Okinawa today.
Toyota and the Japan Association of Automobile Manufacturers have been informed of the Results of his study.
