The use of Bluetooth-enabled devices remains popular. New products (such as mobile phones, laptops and fitness trackers) still support this protocol and have even launched with more recent versions (e.g. Samsung S23 family of phones, iPhone 14 and 14 Pro, Apple Watch Series 8/SE/Ultra all shipped with Bluetooth 5.3). I had previously written about surveying the trend of Bluetooth vulnerabilities back in 2021 [1]. As roughly a year or so has passed, it was a timely moment to review how things may have evolved with respect to the vulnerabilities discovered. Compared to the previous diary, the current Bluetooth core specification has been bumped up to 5.3 (from 5.2 as compared to the previous diary) [2].
