Cyber expert: Investors should get serious about smart cars being hackable

When the New York International Auto Show kicks off on March 30, the world’s leading manufacturers will showcase a wide range of new high-tech and futuristic vehicles.

But there is a downside to all of the ‘smart’ and ‘connected’ technology that is finding its way into today’s automobiles. While the innovation offers new features and conveniences for consumers, it also makes vehicles more vulnerable to hackers.

That is a problem which the auto industry is not fully prepared for and it probably never will be.

As cars are increasingly computerized, they are becoming more reliant on software and firmware than ever before. And anyone who’s ever owned a PC should know that there is no such thing as 100 percent secure software.

Just consider how often computer patches are rolled out. Every software product has some type of inherent vulnerabilities, and even well-designed software still has features and weaknesses which hackers can learn to exploit. As the auto industry turns our cars into computers on wheels and then gives them connectivity via cellular signals, WiFi or Bluetooth, it is enabling new attacks on these systems by malware and remote hackers.

Automakers are trying to address these new threats, but there is no way to prevent them completely.

Adding to the risk, these new vehicle features are managed by technology which has significant underlying vulnerabilities.

The CAN bus (controller area network) is essentially the hub for microcontrollers and devices inside the car. This technology dates back to the early 1980s. The ECUs (electronic control units), which are the embedded devices inside the car controlling specific functions, like the engine, suspension, brakes, transmission, speed control, etc., also contain many design weaknesses which can be exploited by a hacker.

Security updates and patches are common in the software world. But it is one thing to issue a patch for a vulnerability in a PC and quite another when it is a software glitch in a car that could allow remote access to the transmission.

In 2015, security researchers demonstrated a Hollywood-style cyber attack on a Jeep Cherokee as it drove down a St. Louis highway. The hackers were able to gain remote access from several miles away and control key functions of the car like brakes, steering, and transmission. This is an extreme attack and probably not very likely to occur in the real world — at least for now. But it doesn’t mean that less sensational threats will be any less worrisome.

The problem with patching cars

Malware and weaponized exploits are a constant issue for every software and firmware company in existence. There is no reason why we won’t see them in high numbers for vehicle-related systems as well.
