There are currently an estimated 4.9 billion embedded systems distributed worldwide. By 2020, that number is expected to have grown to 25 billion. Embedded systems can be found virtually everywhere, ranging from consumer products such as Smart TVs, Blu-ray players, fridges, thermostats, smart phones, and many more household devices. They are also ubiquitous in businesses where they are found in alarm systems, climate control systems, and most networking equipment such as routers, managed switches, IP cameras, multi-function printers, etc. Unfortunately, recent events have taught us these devices can also be vulnerable to malware and hackers. Therefore, it is highly likely that one of these devices may become a key source of evidence in an incident investigation. This paper introduces the reader to embedded systems technology. Using a Blu-ray player embedded system as an example; it demonstrates the process to connect to and then access data through the serial console to collect evidence from an embedded system non-volatile memory.
