You turn on a light bulb, and it lights up. Simple, right?

And yet, behind that light lies a fascinating — and incredibly complex — world. Starting with a simple everyday object, this talk takes you on a reverse-engineering journey into a consumer smart light bulb. The goal: to understand how the industry has transformed a tiny piece of code that makes an LED light up into a digital fortress packed with security mechanisms. From secrets buried deep in silicon to embedded architectures and regulatory requirements such as RED and the CRA, we’ll discover that the “S” in IoT really does exist: it stands for Security — and it accounts for most of the code written by developers.
