PerfektBlue Bluetooth Vulnerability Exposes Millions of Vehicles to Remote Hacking Threats

A critical new exploit known as the PerfektBlue Bluetooth vulnerability has been uncovered, putting millions of vehicles at risk of remote hacking. This newly discovered flaw affects both Bluetooth Low Energy (BLE) and classic Bluetooth protocols, which are integrated into modern vehicle systems, including infotainment units, keyless entry modules, and telematics platforms. Security researchers state that with this type of vulnerability, the attackers might be able to communicate with cars, leaving the physical contact behind.

The PerfektBlue Bluetooth vulnerability affects a wide range of vehicles from top automakers, including Tesla, BMW, Toyota, Ford, and Hyundai. Most vulnerable models were released between 2016 and 2024 and feature built-in Bluetooth connectivity. This hack can allow cybercriminals to start car engines, unlock a car, switch it off, access GPS data, turn the internal microphones on and much more without being anywhere nearby. In severe cases, they could push malicious firmware updates over the air, potentially giving them long-term access to the vehicle’s systems.

According to experts, the PerfektBlue Bluetooth vulnerability poses a significant risk to personal vehicles and fleets operators, ride-share services, and smaller rental agencies, where the connected vehicles are widely used. And motorists are also asked to disable the Bluetooth when it is not working or not to connect to other foreign devices or consult their vehicle companies on software patches or improvement in the firmware.

As the automotive industry grows more dependent on wireless connectivity, the PerfektBlue Bluetooth vulnerability highlights the urgent need for enhanced security measures, such as strong encryption, multi-factor pairing, and rigorous vulnerability testing. This incident isn't a case of it will never happen to me, but rather a gentle reminder, that car cybersecurity is no longer beneficially, it is obligatory.
