About Stephen Sims

Stephen Sims began working on computers at a young age with a fellow enthusiast: his father. Amazed by how easy it was to change an application's intended behavior, Stephen was quickly hooked. Today, he's an industry expert with over 20 years of experience in information technology and security. He's authored SANS most advanced course, SEC760: Advanced Exploit Development for Penetration Testers, was the 9th person in the world to earn the GIAC Security Expert certification (GSE), and co-author of the Gray Hat Hacking book series, as well as a keynote speaker who's appeared at RSA USA and APJ, DEF CON, OWASP AppSec, BSides events and more. On top of all this, Stephen is Curriculum Lead for SANS Offensive Operations.
