Assessment of Fitness Tracker Security: A Case of Study

Abstract

The wearable industry has experienced a notable growth over the last decade, especially in fitness or e-health trackers. These trackers bring new functionalities that require collecting a great amount of sensitive information about the user. This fact has made fitness trackers the target of deliberate attacks, e.g., eavesdropping, unauthorized account access, fake firmware update, and so on. For this reason, this paper describes a vulnerability study on one of the most popular fitness trackers in 2017, together with the mobile application associated to the tracker. The study results show what vulnerabilities of the communications among agents (i.e., wearable device, mobile application and server) could put at risk users sensitive information and privacy.
