The Mirai botnet has brought public awareness to the danger of poorly secured embedded devices. Its ability to propagate is fast and reliable. Its impact can be devastating and variants of it will be around for a long time. You need to identify it, stop it, and prevent its spread. I had the opportunity to become familiar with the structure, design, and weaknesses of Mirai and its variants. At this talk you’ll learn how to detect members of the botnet, mess with them through various means and setup a safe live fire lab environment for your own amusement. I will demonstrate how to join a C2 server, how to collect new samples for study, and some changes that have occurred since release of the source code. By the end you’ll be armed and ready to take the fight to these jerks. Unless you’re a botnet operator. Then you’ll learn about some of the mistakes you made.
