This week, I’d like to share an engaging presentation I recently had the opportunity to deliver on social media regarding an underappreciated Apple service that deserves more local attention:. While Apple hasn’t revealed the exact number of CarPlay users, it’s likely one of its most utilized services. One of the most pressing concerns is the potential threat to driver security and privacy. So, how safe is CarPlay?
At the TROOPERS24 IT convention in Heidelberg, Germany, safety researcher Hannah Nöttgen delivered an insightful presentation titled “On This Session”, where she thoroughly examined CarPlay’s underlying safety architecture to assess its actual safety value. She explains that CarPlay relies on two primary protocols: the proprietary iAPv2, used for authentication, and AirPlay, which handles media streaming. These features collectively enable seamless access to the expertise we’ve grown accustomed to, permitting drivers to receive messages, answer calls, listen to music, and utilize various other functions without needing to unlock their phones.
While this comfort comes with inherent dangers.
Nöttgen’s comprehensive evaluation delved into various avenues of vulnerability, focusing intensely on the risks associated with unauthorised access to sensitive information that could compromise drivers’ privacy and security. While CarPlay’s authentication system provides robust protection against replay attacks, Nöttgen uncovered alternative vulnerabilities such as denial-of-service (DoS) attacks targeting the wireless connection, which, although challenging to execute, remain feasible and pose a threat.
Apple’s stranglehold on CarPlay hardware is another intriguing aspect, exercised through its Made for iPhone (MFi) program with deliberate precision. All licensed CarPlay units must include an Apple-issued authentication chip, for which automakers pay a fee to integrate into their vehicles. While Apple’s closed ecosystem has faced criticism for restricting third-party access, it also presents a substantial barrier to potential threats. To initiate a sophisticated attack on an iPhone’s encryption, an attacker would require physical access to the device’s MFindependent processing unit (MFi) chip.
Nöttgen concluded her address by highlighting the need for further investigation into areas such as key extraction methods and comprehensive testing of CarPlay’s communication protocols. The primary worry is that if these encryption keys fall into the wrong hands, malicious actors could potentially intercept and decipher sensitive data.
Unfortunately, the proprietary nature of individual IAPv2 implementations and Apple’s custom AirPlay solution render impartial safety verification significantly challenging. We highly recommend devoting sufficient time to exploring Hannah Nöttgen’s thought-provoking work, as it offers a captivating and engaging reading experience.
