A foundational component of communication between devices is the TCP/IP network stack. Web browsing, streaming video, secure control, and innumerable other applications are built upon this technology. This 2-part demonstration will use open source tools to focus on the data transfer components UDP and TCP while targeting an IoT device. Part 1 is reverse-engineering the network commands to better understand them and then mimic it (a common attack strategy). Network protocols will be discussed during this process. Armed with our new knowledge and skills, part 2 will take them a step further to discover and analyze malware present on the IoT device. This presentation is light on slides and heavy on demos.
