9. **Keyless Entry and Relay Attacks**The convenience of keyless entry systems, which allow drivers to unlock and start their vehicles without physically using a key, has unfortunately opened a new avenue for sophisticated vehicle theft. This modern amenity has become a hacker’s dream, susceptible to what are known as relay attacks. These attacks exploit the wireless signals exchanged between a car and its key fob, effectively bypassing traditional physical security measures.
In a relay attack, criminals employ signal-boosting devices to intercept and extend the range of the key fob’s signal. One device is placed near the owner’s key fob (e.g., inside a home), while another is held near the vehicle. This tricks the car into believing the key fob is within close proximity, allowing thieves to unlock doors and even start the engine without ever possessing the physical key. This method is alarmingly effective, with research indicating that nearly 50% of stolen cars in the UK in 2022 were taken using keyless entry exploits.
High-profile incidents underscore the prevalence of this threat. For example, in 2021, Toyota and Lexus vehicles were targeted by attackers who cloned key fobs through relay attacks, boosting signals to unlock and drive cars without the owners’ permission. The “PerfektBlue” Bluetooth vulnerability, discovered more recently, also exposed millions of vehicles to remote hacking, enabling attackers to unlock doors, start engines, and potentially access critical vehicle systems without physical contact.
For consumers, protecting against these subtle yet potent threats is paramount. Storing key fobs in a Faraday pouch, a signal-blocking case, when not in use can effectively prevent signal interception. Employing traditional security measures like a steering wheel lock adds a physical deterrent, and drivers should explore disabling passive keyless entry features in their car’s settings if the option is available to them.
