ARE PHONE AS A KEY AND OTHER KEYLESS ENTRY SYSTEMS SAFE?

EV Channels Review

This video delves into the security of keyless entry systems, particularly focusing on Tesla's 'phone as a key' (PaaS) feature, prompted by a real-world incident where a Tesla owner accidentally drove off in the wrong identical vehicle. The presenter, Nikki Gordon-Bloomfield, explains the underlying cryptography of modern key fobs, highlighting the shift to rolling codes to prevent replay attacks. While acknowledging the sophistication of these systems, the video points out vulnerabilities like relay attacks. It then examines PaaS, noting that while potentially more secure due to software updates and powerful phone processors, it introduces additional attack vectors. The incident with the two Teslas is speculated to be a result of user error (unlocked car or valet mode) or a software bug, rather than a sophisticated hack. The review concludes with practical advice for owners, such as not leaving fobs near doors, using strong security practices for connected services, and deactivating features if concerned. The presenter expresses personal concern for Tesla owners, suggesting deactivating PaaS until the issue is fully understood.
