Tesla Cars Hacked through Mobile App

‘Tis the season for giving, but Tesla may be offering more than what was originally planned.

If you’re a hacker, and you want a new Tesla car for the holidays, all you have to do is access the company’s smartphone app.

New research shows that Tesla cars can be stolen by hacking the company’s smartphone app.

Tesla Cars Vulnerable
According to SCMagazineUK, Norwegian app security firm Promon has demonstrated through research that cyber-criminals could take control of Tesla vehicles, to the point where they can locate, unlock and drive the car away unhindered. Such a hack, possible by exploiting a lack of security in their smartphone app, gives criminals total control of the vehicle, providing additional functionality to that exposed by Keen Security Labs in a different hack in late September.

This is all done by attacking and taking control of the Tesla app. This underlines the vital importance of app security, and the wider implications this could have for IoT-connected devices in general. (IoT refers to the ever-growing network of physical objects that feature an IP address for internet connectivity, and the communication that occurs between these objects and other internet-enabled devices and systems.) Most people understand the importance of online website security – and only visiting sites that constantly check for vulnerabilities, but few consider the potential issues with mobile security.

Tom Lysemose Hansen, founder and CTO at Promon, said: “Keen Security Labs’ recent research exploited flaws in the CAN bus systems of Tesla vehicles, enabling them to take control of a limited number of functions of the car. Our test is the first one to use the Tesla app as an entry point, and goes a step further by showing that a compromised app can lead directly to the theft of a car.”

One way for the hack to work is for cyber-criminals to set up a Wi-Fi hotspot close to a public Tesla charging point. When Tesla users log in and visit a page, an advert targeting car owners appears, offering an incentive such as a free meal. When clicking this link and downloading the accompanying app, hackers can gain access to the user’s mobile device, which enables them to attack the Tesla app.

According to Hansen, the ease with which any tech-savvy criminal can steal a Tesla car in this way is indicative of a need for a much greater focus on in-app security across all IoT-connected devices and applications. “Mobile-focused criminals are more skilled than ever before and are using a lack of security in mobile apps as an increasingly lucrative source of revenue. Remotely controlling and stealing Tesla cars is a particularly dangerous example of just what can be done, but in theory, any app without the necessary protection in place could be affected.

“One way to achieve this is by introducing self-defending app software that protects the app from the inside out, greatly reducing the possibility of a cyber-attack. By moving away from having a physical car key to unlock the door, Tesla is basically taking the same step as banks and the payment card industry. Physical tokens are replaced by ‘mobile tokens’. We strongly believe that Tesla and the car industry needs to provide a comparable level of security, which is certainly not the case today.”

Hansen concluded: “Tesla is a shining example of how technological advances are providing unprecedented levels of innovation and user convenience. However, our increasingly app-focused world needs to be urgently secured, to prevent criminals from seizing their opportunity on a large scale.”
