Why This Matters
Vehicles are now rolling computers. Understanding their digital vulnerabilities is just as important as crash safety ratings.
What is Car Hacking?
Modern vehicles contain 100+ electronic control units (ECUs) connected via internal networks. Hackers can exploit wireless entry points—Bluetooth, WiFi, cellular modems—to access these systems and potentially control steering, brakes, or engine.
Why OTA Updates Matter
Over-the-Air updates can patch vulnerabilities remotely, but they also create new attack surfaces. If the update channel is compromised, attackers can push malicious firmware to millions of vehicles simultaneously.
The CAN Bus Problem
The Controller Area Network (CAN bus) was designed in the 1980s without security in mind. Messages are broadcast without authentication, meaning any device on the bus can send commands to any other device—including safety-critical systems.
Connected Car Risks
Always-on cellular connections, companion apps, and cloud services expand the attack surface far beyond the vehicle itself. A vulnerability in a mobile app or backend server could compromise the entire fleet.
Key Fob Relay Attacks
Relay attacks amplify the key fob signal to trick the car into unlocking. Thieves use two devices—one near the fob and one near the car—to relay signals across hundreds of meters. UWB technology is the strongest countermeasure.
How We Score
Our scoring methodology weights six attack vectors based on real-world impact and exploitability. Scores factor in known CVEs, manufacturer response times, architectural protections, and independent security research findings.
