From the Ground Up!

Welcome back to BSidesSF CTF! For those of you able to join us in person, we're so happy to have you back. This year, we've partnered with BSides Buffalo to bring our CTF to even more players. For support, please join the #ctf channel on the BSidesSF Slack.

The game will run for 48 hours:

  • Start: 2022-06-03 17:00:00 PDT (2022-06-04 00:00:00 UTC)
  • Stop: 2022-06-05 17:00:00 PDT (2022-06-06 00:00:00 UTC)


  1. Admin decisions are final.
  2. Scoreboard and infrastructure is out of scope. Attempting to attack conference or game infrastructure will result in a ban.
  3. Teams must have an on-site presence to claim prizes.
  4. No modifying challenges to make them unsolvable. No altering flags.
  5. Be good to one another.
