In this episode of Security Nation, Jen and Tod chat with Gordon “Fyodor” Lyon, author of the widely used open-source Nmap Security Scanner. On the doorstep of Nmap’s 25th anniversary, Gordon and our hosts talk about the tool’s impact on asset management, as well as the struggles and triumphs of creating and managing the solution. They even cover a few highlights from Hollywood films where Nmap makes a guest appearance.

Stick around for our Rapid Rundown, where Tod and Jen talk about a recent warning from the FBI that decentralized finance (DeFi) – i.e., cryptocurrency – poses some unique risks, which attackers are already exploiting.
