Chasse Partie Systems CTF
Hybrid - Online and In-person
Friday and Saturday: 10:00 - 18:00
Sunday: 10:00 - 13:00
West Hall 4
The inception of this distinctive event occurred at DEF CON 31, initiated by a fortuitous encounter with CookieT while participating in LineCon for merch. Our shared passions fostered an immediate bond, and it was amidst this camaraderie that the idea for a future challenge germinated. Having previously engaged participants with puzzle-embedded challenge coins, I (Chasse) was inspired to expand the concept beyond a mere cipher. The aim was to design a contest that would appeal across a broad spectrum of skill levels by integrating a variety of puzzles, both modern and traditional, to attract a wider audience from a complete beginner new to the hackerspace to the more seasoned and advanced hacker. Observing the collective enthusiasm as participants unraveled the first simple coin puzzle was exhilarating, yet the quick resolution of the puzzle occasionally detracted from the overall experience for more advanced puzzle solvers. Throughout DEF CON 31, CookieT and I explored the feasibility of a web-based challenge CTF, laying the foundation for what would evolve into a pioneering contest and experience. Later Raven emerged from the shadows of cyberspace to help us chisel out the contest from Zeroes and Ones
With the announcement of DEF CON 32's theme, our concept was honed, ready to blend our creative talents into this year's challenge. We crafted an innovative combination of a narrative-driven journey game, scavenger hunt, and web-based Capture The Flag (CTF) challenges, all meticulously aligned with the DEC CON 32 "Engage" theme. This contest emerges as a holistic platform, introducing DEF CON newcomers to core security principles through an engaging narrative. Spanning a variety of fields including OSINT, cryptography, radio, telephony, password, and web security. It promises a rich, diverse experience! Participants, automatically divided into teams, are propelled on a quest to decode puzzles and unearth flags, with challenges designed to suit everyone from novices to veterans seeking sophisticated, intricate challenges. This contest transcends the conventional competition framework, evolving into an artful endeavor that illustrates the symbiosis of storytelling and technical puzzles to create a deeply immersive learning adventure. Imagined as an interactive storybook, it invites attendees to navigate their own routes, making their own choices that lead them through a story-rich exploration of security concepts and engagement even with each other.
The technical infrastructure of this experience is built on varied technologies. The main website, https://www.chassepartie.com, is developed with Ruby on Rails 7.1 and hosted on Heroku, with CloudFlare acting as our Web Application Firewall (WAF). This site functions as the scoreboard and narrative hub of the contest. Additionally, we have set up an XCP-NG hypervisor to host approximately 10 to 15 virtual machines as targets for participant engagement. Augmented reality markers are also in place, intended for deployment in communal areas like sticker boards, to enhance the experience. These elements are interwoven with the storyline, guiding attendees through what we believe is an unprecedented adventure-style CTF challenge named Chasse Partie Systems – Dystopian Apocalypse Resistance Terminal.
So come and join us on our deviant journey, what are you waiting for?
