PerfektBlue: Bluetooth Vulnerabilities in Car Infotainment

🔒 Researchers have identified a chain of four Bluetooth vulnerabilities collectively named PerfektBlue in the OpenSynergy Blue SDK, used in millions of vehicles. An attacker that pairs via Bluetooth can exploit AVRCP flaws to execute code on the head unit and inherit its Bluetooth privileges, potentially accessing microphones, location data, and personal information. Vehicle owners should update head-unit firmware when patches are available and disable Bluetooth when not in use.
