As countries worldwide expand their deployment of 5G networks, Taiwan is also catching up by promoting the widespread adoption of 5G network services and introducing numerous 5G User Equipment (UE). In this session, our focus will be on industrial-grade communication Internet of Things (IoT) devices, with the goal of "Pwn it before open it." This aims to enable successful research and yield findings before obtaining the physical product. The content will revolve around sharing the hurdles encountered during the research process, the methods employed to overcome them, and the approach to research. We will also share the cybersecurity vulnerabilities discovered in industrial-grade communication IoT devices and methods for mitigation and prevention.
