Twine is a consumer device that provides remote environmental monitoring through a variety of sensors, such as moisture, temperature, vibration, etc... We will discuss our analysis of Twine, and will lead you through the steps taken to understand what's going on under the hood of a "black box" device. The audience will be introduced to the challenges faced, and to the different approaches that can be leveraged to understand (and exploit!) embedded devices (the fridge that tweets and similar devices). Topics include: capturing traffic on a non-proxy aware device, obtaining and reverse engineering the firmware, analyzing opaque binary traffic, emulating a Twine device and gaining console access via the debug serial port.
