These days IoT devices are an easy entry point for malicious users to invade users’ privacy. With that in mind, we tested the AEG Smart Scale PW 5653 BT, specifically the Bluetooth security (Bluetooth Low Energy or BLE). We also tested the mobile applications Smart Scale for Android and Smart Scale for iOS. To complete our tests, we used our commercial static application security testing tool CxSAST, some tools we made ourselves, and open source software.
