Connected Cars Technology Vulnerable to Cyber Attacks

Trend Micro report analyses cyber attacks on the road and how to mitigate them

AUCKLAND, March 2, 2021 – Trend Micro Incorporated (TYO: 4704; TSE: 4704), a global leader in cybersecurity, today announced a major new study into connected car security that describes multiple scenarios in which drivers could encounter attacks that threaten the safety of themselves and others.

The report reveals the scope of the cybersecurity risks examined. Researchers evaluated 29 real-world attack scenarios according to the DREAD¹  threat model for qualitative risk analysis. These attacks could be launched remotely against and/or from victim vehicles. Examples and highlights include:

• DDoS attacks on Intelligent Transportation Systems (ITS) could overwhelm connected car communications and represent a high risk.
• Exposed and vulnerable connected car systems are easily discovered, making them at higher risk of abuse.
• Over 17% of all attack vectors examined were high risk. These require only a limited understanding of connected car technology and could be accomplished by a low-skilled attacker.
   

“Our research shows that there are ample opportunities for attackers looking to abuse connected car technology,” said Dr Jon Oliver, Director and Data Scientist, Trend Micro. “Fortunately, there are currently limited opportunities for attacks, and criminals have not found reliable ways to monetise such attacks. With the U.N.’s recent regulations requiring all connected cars to include cybersecurity, as well as a new ISO standard underway, now is the time for stakeholders across the industry to better identify and address cyber risk as we accelerate towards a connected and autonomous vehicle future.” ²

More than 125 million passenger cars with embedded connectivity are forecast to ship worldwide between 2018 and 2022, and progress continues to advance towards fully autonomous vehicles. This advancement will create a complex ecosystem comprising cloud, IoT, 5G and other key technologies. It also features an enormous attack surface comprising potentially millions of endpoints and end users.

As the industry develops, there will be multiple opportunities for monetisation and sabotage for cybercriminals, hacktivists, terrorists, nation states, insiders and even unscrupulous operators, the report warns. Of all 29 attack vectors studied, the overall risk of successful cyber attacks was assessed as Medium. However, as SaaS applications become embedded in the Electrical/Electronics (E/E) architecture of vehicles and cybercriminals create new monetisation strategies, an evolution in attacks will lead to higher risk threats.

To mitigate the risks outlined in the study, connected car security must be designed with an integrated view of all critical areas to secure the end-to-end data supply chain. Trend Micro has the following high-level guidance for protecting connected cars:

• Assume compromise and have effective alert, containment, and mitigation processes.
• Protect the end-to-end data supply chain across the car’s E/E network, the network infrastructure, backend servers, and VSOC (Vehicle Security Operations Center).
• Apply lessons learned to further strengthen defenses and prevent repeat incidents.
• Relevant security technologies include firewall, encryption, device control, app security, vulnerability scanner, code signing, IDS for CAN, AV for head unit, and much more.
