A Systematic Survey of Firmware Extraction Techniques for Iot Devices
Breaking all the Things | A Systematic Survey of Firmware Extraction Techniques for IoT Devices Sebastian Vasile, David Oswald, and Tom Chothia University of Birmingham [email protected], [email protected], [email protected] Abstract. In this paper, we systematically review and categorize differ- ent hardware-based firmware extraction techniques, using 24 examples of real, wide-spread products, e.g. smart voice assistants (in particular Amazon Echo devices), alarm and access control systems, as well as home automation devices. We show that in over 45% of the cases, an exposed UART interface is sufficient to obtain a firmware dump, while in other cases, more complicated, yet still low-cost methods (e.g. JTAG or eMMC readout) are needed. In this regard, we perform an in-depth investiga- tion of the security concept of the Amazon Echo Plus, which contains significant protection methods against hardware-level attacks. Based on the results of our study, we give recommendations for countermeasures to mitigate the respective methods. 1 Introduction Extracting the firmware from IoT devices is a crucial first step when analysing the security of such systems. From a designer's point of view, preventing the firmware from falling into the hands of an adversary is often desirable: for in- stance, to protect cryptographic keys that identify a device and to impede prod- uct counterfeit or IP theft. The large variety of IoT devices results in different approaches to firmware extraction, depending on the device in question. Past work has looked at the state of security of IoT devices, e.g. -

Meet Vanessa Carpenter and Diesel Møbius, SparkFun customers and developers of the Critical Corset. Using a Polar heart rate monitor, an Arduino, and a cleverly hidden air pump system, Vanessa and Diesel designed a corset that explores the rules of attraction. As the user’s heart rate increases, the corset gently tightens, creating a more confident posture. Whether you need a heart rate monitor or just a handful of LEDs, the tools are out there.
