Larry is the Product Security Research and Analysis Director at Finite State, focused on XoT security issues. He also co-hosts the international award winning podcast, Paul's Security Weekly, and likes to tinker with all things electronic and wireless, much to the disappointment of his family, friends, warranties, and his second Leatherman Multi-tool. A self-professed lifelong "tinkerer and explorer", Larry always wanted to know how things work. "My dad built the family television from a kit, and I helped. It caught fire. Twice. I helped fix it both times." Larry is a Principal SANS Instructor, and appropriately, co-author of SEC617: Wireless Penetration Testing and Ethical Hacking, and SEC556: IoT Penetration Testing. In his spare time, Larry enjoys being a ham radio operator, spending time with his family, and getting outdoors. He loves working with his hands, whether in his vegetable garden, building electronics, or wood working and blacksmithing in the pursuit of knife making.
