Tesla updates iPhone app to boost precision tracking and security akin to Apple AirTag tech

Tesla has rolled out a significant update to its iPhone app, introducing ultra-wideband (UWB) support in version 2024.2.3. This enhancement, highlighted by Not a Tesla App, brings a more robust and secure digital key experience compared to Bluetooth technology.

UWB’s precision tracking enables the car to pinpoint the exact location of the key, minimising the risk of replay spoofing attacks.

What are replay spoofing attacks?

Replay spoofing attacks involve cybercriminals intercepting secure network communications, then fraudulently delaying or resending them to misdirect receivers. Spoofing entails pretending to be something else to gain trust or access, steal data, or spread malware.

Improved Precision and Security

The implementation of UWB extends beyond mere security measures. It enables the car to discern which user is approaching the driver’s side, particularly useful in scenarios where multiple individuals with phone keys are accessing the vehicle simultaneously. This level of precision tracking is akin to the technology behind Apple AirTags, ensuring accurate locating even in challenging environments, The Verge reported.

Although currently exclusive to iPhones, this advancement hints at a potential expansion to Android devices, especially considering recent models like Google Pixel and Samsung Galaxy phones incorporating UWB chips.

Upon updating to the latest version, users will be prompted to “Upgrade Your Phone Key,” granting the app access to Nearby Interactions via the iPhone’s U1 chip. This setting can be located under Settings > Privacy & Security > Nearby Interactions.
