Internet connectivity in cars comes with security risks

Audi’s connect comes with an array of internet-enabled features

Audi has just announced the European launch of Audi connect SIM, a wi-fi hotspot built into its new models to allow Europe-wide data roaming.

In Singapore, similar models like the Audi A3 also come with Audi connect to enable drivers to enjoy a variety of applications such as checking the traffic situation, navigating the road and access to Twitter via Bluetooth connection with their mobile phones.

Audi is not alone in recognising that motorists want seamless internet connectivity in their cars, with manufacturers such as Ford, GM and Chrysler also offering similar features.

With easier internet access, a key issue that drivers have to consider is the capability of their cars to withstand hacking.

Associate Professor Anwitaman Datta from the School of Computer Science and Engineering at Nanyang Technological University (NTU) warned, “The risks of internet integration with a car are already imminent since it potentially opens up an additional attack surface.”

This was demonstrated in July 2015 when two researchers announced that they had found a way to hack into a Jeep’s integrated internet connection and take control of several key functions. These included tracking the car’s location, and controlling its lights, navigation systems, and even steering.

The researchers had gained access to the different systems of the car progressively. Prof. Datta said, “Any subsystem or component likely has some vulnerabilities of its own. Thus a composite system inherits those vulnerabilities – and opens up further avenues for exploitation.”

Unfortunately, Prof. Datta said car makers are not doing enough to bolster internet security.

“Manufacturers have no excuse not to be aware of the potential threats, but when it comes to prioritising between features and security, security often takes the back seat,” he said.

Motorists may enjoy reading social media posts or selecting a restaurant at the touch of the screen while on the road as more cars are equipped for greater internet connectivity.

But they should be aware that hackers might be lurking around in the internet highway to steal their vital personal data and passwords.
