Last month, we wrote an introductory overview of our experience running the second annual Car Hacking Village CTF infrastructure at DEF CON 25. Most notably, our use of Zappa to deploy Flask-based CTFd on AWS Lambda and API Gateway resulted in a $1.50 bill for the entire month of July (excluding database instances), while providing a number of operational advantages over last year’s traditional infrastructure.
Each summer, members of the security community convene in Las Vegas for a week of talks, networking, and other activities at a series of conferences. At DEF CON specifically, a number of organizations host Capture the Flag (CTF) hacking competitions in which contestants either compete against each other trying to access other teams’ infrastructure while defending their own (“Attack with Defense”), or by racing to rack up the most points before the contest ends with answering standalone questions (“Jeopardy style”).
