This whitepaper is designed to show some details of the Philips Hue system. It is not designed to demonstrate any specific attack, but instead a chance to “poke around” to see what security features are present. It is designed to serve as a reference for those designing similar systems, to give an idea what attack surfaces might be exploited. This analysis focuses on the embedded hardware itself. In particular, I look at the Bridge 1.0 (round), the Bridge 2.0 (square), the low-cost white light bulbs, and the BR30 color bulb.
