Welcome to PBR!

Welcome to the home of Psi Beta Rho (a.k.a. PBR or ψβρ), UCLA’s competitive cybersecurity team! We are a group of hackers, programmers, and security enthusiasts who love to learn and compete. We are a part of ACM Cyber at UCLA and are advised by Dr. Yuan Tian! Whether we are pwning a binary or attacking a site using cross-site scripting, we like to have fun! If you want to see who is on our team, check out our team page. To see some of our writeups, check out our blog. If you are interested in seeing what we usually talk about, check out our past practices! If you want to see what CTFs we have attended in the past, check out our CTFs page.

What do we do?

We compete in CTFs or Capture the Flag events, where we solve cybersecurity challenges to earn points! Currently, we meet weekly for our practices where we learn about a new topic and solve challenges related to web exploitation, cryptography, binary exploitation, and reverse engineering in addition to regularly competing in CTFs every other weekend. We also regularly invite notable speakers from top CTF teams or industry to hear about their experiences and learn about how to improve our skills to work in research and industry! Additinonally, we work on projects and research related to security including hosting our own CTF annually, LA CTF!

Join Us

These are always open to the public so be sure to swing by! The best way to stay up to date with notifications for our team is to join the ACM Cyber Discord where we send out notifications for practices, upcoming CTFs, and like to hang out and talk about CTFs and cybersecurity.
