This month, the "Big Bugs" podcast is taking a break from its usual format to discuss Capture the Flag (CTF) competitions. The podcast features Kevin Chung, who wrote the open-source CTF framework CTFd, and explores the world of CTFs in general, including their history, types, and applications. CTFs are puzzle-based information security challenges that have become a microculture over the past decade, with three common types: Jeopardy-style, Attack-Defense, and mixed. The podcast also delves into the motivations behind participating in CTFs, discusses interesting ways to apply them, and touches on various aspects of information security such as cryptography and reverse engineering. Additionally, it provides a primer for those unfamiliar with CTFs and highlights popular competitions like DEFCON CTF, which qualify winners to participate in the finals. The podcast also explores the role of CTFd, an open-source framework that helps organizations run CTFs, and discusses why CTFs are loved by many, including their ability to teach/learn hacking skills, use as training programs for developers, and bring people together to solve puzzles.
