BSidesSF CTF 2025

Welcome back to BSidesSF CTF! For those of you able to join us in person, we're so happy to have you back. For support, please join the #ctf channel on the BSidesSF Discord. Please do not ask about the CTF in other channels, we'd like to keep those for the rest of the conference.

Game details

Rules

• Admin decisions are final.
• Scoreboard and infrastructure is out of scope. Attempting to attack conference or game infrastructure will result in a ban.
• Teams must have an on-site presence to claim prizes.
• No modifying challenges to make them unsolvable. No altering flags.
• Be good to one another.
• No limit to team sizes. (It'd be unenforceable anyway.)
• Flags follow the format CTF{} (unless specified explicitly in the challenge description)
• Scoring is dynamic, the amount of points the challenge is worth will reduce over time as the challenges get more solves (as a result, your score may go down over time as other solve the same challenges as you)
• Scores of Onsite challenges will not be included in upload to CTFTime
