Eric McDonald conducted reverse-engineering on the Android-based infotainment system in a 2021 Honda Civic, revealing a significant vulnerability. The head unit can be updated via USB using accessible standard Android Open Source Project (AOSP) test keys. This exploit, named the EvilValet attack, allows anyone with physical access to the car's USB port to execute arbitrary code signed with these test keys. While confirmed only in the 2021 Honda Civic, similar Android-based systems may also be at risk due to shared technology across different vehicle models. This vulnerability raises concerns about vehicle security as it allows unauthorized users to manipulate the system through a USB connection.
