Electric scooters vulnerable to remote hacks Electric scooters are steadily becoming a popular alternative for short commutes. Besides convenience, however, they also introduce a range of cybersecurity and privacy risks, according to a study by the University of Texas at San Antonio (UTSA). The review which UTSA said is “the first review of the security and privacy risks posed by e-scooters and their related software services and applications” outlines various attacks scenarios that riders might face, as well as how to tackle the risks. Many e-scooters rely on a combination of Bluetooth Low Energy (BLE) and the rider’s smartphone internet connection to run, as well as send data to the service provider. This opens up a number of avenues for potential attacks. For example, bad actors could eavesdrop on the data being broadcasted, which could, in turn, lead to Man-in-the-Middle (MitM) and replay attacks. Those could allow hackers to
