1. How Are Computers Used in Modern Motor Vehicles?

Modern vehicles rely heavily on computers, utilizing Electronic Control Units (ECUs) to manage a multitude of functions, from essential systems like steering, braking, and acceleration to convenience features such as lights and windshield wipers. These ECUs enable precise control and optimization of vehicle performance. According to a report by McKinsey, the average car has over 100 million lines of code, highlighting the complexity of modern automotive software.

Wireless capabilities are integrated into numerous vehicle components, including keyless entry systems, ignition controls, tire pressure monitoring, and entertainment systems. While manufacturers try to minimize interactions between different vehicle systems and wireless communications, these connections create potential access points for cyberattacks. Third-party devices connected to the vehicle, especially through the diagnostics port, can introduce further vulnerabilities by adding connectivity where it previously didn’t exist.

2. What Are Some Ways an Attacker Can Access Vehicle Networks and Driver Data?

Attackers can exploit vulnerabilities in several ways to access vehicle networks and driver data. These vulnerabilities can be found in a vehicle’s wireless communication functions, mobile devices connected to the vehicle (via USB, Bluetooth, or Wi-Fi), or third-party devices connected through the diagnostic port.

An attacker could remotely exploit these weaknesses to gain access to the vehicle’s controller network or data stored on the vehicle. While not all vulnerabilities allow complete system access, the risk to consumer safety increases significantly if critical vehicle control systems can be manipulated.

According to a study by the University of California, Berkeley, vulnerabilities in vehicle software can allow attackers to disable brakes, control steering, and even shut down the engine remotely. The study emphasized the need for robust security measures to protect against such threats.

3. Can You Provide Examples Of Recently Demonstrated Remote Exploits?

In recent years, security researchers have demonstrated several alarming remote exploits in modern vehicles. One notable case involved a 2014 passenger vehicle, where researchers identified multiple vulnerabilities in the radio module. Their detailed findings were published in a whitepaper in August 2015, demonstrating how attackers could exploit active cellular wireless and user-enabled Wi-Fi hotspot communication functions.

Attacks conducted over Wi-Fi were limited to a range of about 100 feet. However, by making a cellular connection to the vehicle’s cellular carrier, an attacker could communicate with and exploit the vehicle from anywhere on the carrier’s nationwide network via an Internet Protocol (IP) address.

The compromised radio module, connected to two Controller Area Network (CAN) buses, allowed researchers to manipulate various vehicle functions, including:

• At Low Speeds (5-10 mph):

  • Engine shutdown
  • Disabling the brakes
  • Steering control

• At Any Speed:

  • Door locks
  • Turn signals
  • Tachometer
  • Radio, HVAC, and GPS

This demonstration highlighted the severe risks associated with vehicle cybersecurity vulnerabilities.

4. What Steps Did The Manufacturer Take To Fix Or Mitigate The Vulnerabilities Identified?

Following the demonstration of remote exploits, the National Highway Traffic Safety Administration (NHTSA) determined that the vulnerability represented an unreasonable risk to safety. Key factors included the ability to access and manipulate critical vehicle control systems, the large number of vehicles potentially at risk, and the high likelihood of exploitation, particularly given the researchers’ plans to publish their findings.

As a result, nearly 1.5 million vehicles were recalled under NHTSA Recall Campaign Number 15V461000. Before the researchers released their report, the cellular carrier for the affected vehicles blocked access to a specific port (TCP 6667) for the private IP addresses used to communicate with the vehicles. However, the recall was still necessary to address other short-range vulnerabilities.

The manufacturer notified affected vehicle owners and provided a USB drive containing a software update with additional security features. Owners could also visit a website to check if their vehicle was included in the recall and download the software update to a USB drive. For those who preferred not to install the update themselves, the option to have a vehicle dealer install the update was available.

This comprehensive approach aimed to mitigate the identified vulnerabilities and prevent potential exploits.

5. How Can Consumers Determine Whether Their Vehicle Has Been Recalled for a Cybersecurity Issue?

When a vehicle is subject to a recall, the manufacturer sends a notification to vehicle owners, detailing the issue and explaining how to obtain a free remedy. Staying informed about the latest recalls and updates is essential for vehicle owners.

Consumers can stay informed by:

• Visiting NHTSA’s safercar.gov website.
• Monitoring media and news announcements of recalls.
• Contacting the nearest vehicle dealership.
• Checking the vehicle manufacturer’s website for recall-related information.

Vehicle owners should check their vehicle’s VIN for recalls at least twice a year via the NHTSA website.

Consumers can also find related information for their vehicles on these websites. By staying proactive, vehicle owners can ensure they are aware of any cybersecurity-related recalls affecting their vehicles.

6. How Can Consumers Minimize Vehicle Cybersecurity Risks?

Consumers can take several steps to minimize the risk of vehicle cybersecurity threats. Here are four key recommendations:

1. Ensure Your Vehicle Software is Up to Date:

   • If a manufacturer issues a software update notification, verify its authenticity and take prompt action to update the vehicle system. Be cautious of socially engineered emails that may trick you into downloading malicious software. Always verify recall notices and software updates on the manufacturer’s official website. Avoid downloading software from third-party websites or file-sharing platforms. Use a trusted USB or SD card for downloading and installing software. If unsure, consult your vehicle dealer or manufacturer for assistance.

2. Be Careful When Making Modifications to Vehicle Software:
