Hardcoded AES Keys in Setracker2 Android App

Executive Summary

The Setracker2 Android Companion App versions 3.1.5 and earlier use static hardcoded AES encryption keys and initialization vectors to encrypt communication between the watch and its backend server.

Because these keys and vectors are hardcoded and static, an attacker can obtain them and decrypt the traffic sent from the Setracker2 watch, compromising the confidentiality of the data.
