After a few years of incident response in a very large and crazily diverse environment, Brian Butterly (@BadgeWizard) has changed back into a more offensive area. Focusing on operational technology and the railway sector, he’s applying his knowledge from past projects in the areas of embedded-, hardware-, mobile-, and telecommunications-security to ginormous vehicles driving at high speeds and everything surrounding them. While combining a closed environment and good old hacking spirit results in a fair amount of challenges, he’s doing his best to fuse both world together and carry on sharing fun insights.
