Shining some light on the Amazon Dash button

Presented at 33C3 (2016), Dec. 28, 2016, 11 p.m. (60 minutes).

This talk will explore the hard- and software of the Amazon Dash button. While the old hardware-revision of the button has already been analyzed and can be repurposed easily, the new hardware-revision is locked more tightly to prevent tinkering. In this talk a detailed teardown of the dash button hardware will be given. The talk will also have a closer look at the software running on the device and how communication with the server works. Although the new hardware-revision of the button makes use of the controller lockbits to prevent the user from reprogramming the device, a method for running custom code on the device and extracting stored secret keys will be presented.
