My name is Benson! I’m a computer science major at UCLA who has an interest in cybersecurity! I compete in a lot of CTFs or Capture the Flag competitions which are jeopardy-style cybersecurity events. I have interned at a variety of companies in security related roles such as Microsoft, Trail of Bits, and CrowdStrike. Previously, I was one of the Co-Presidents for ACM Cyber at UCLA and the Director for Psi Beta Rho, UCLA’s competetive cybersecurity team! I also founded UCLA’s largest cybersecurity competition, LA CTF!

This site is a collection of articles and writeups I have written for various cybersecurity related topics and CTF challenges. If you are interested in reading about some of my thoughts on cybersecurity topics I find interesting, check out some of my articles. If you want to see some of my writeups to the challenges I have solved or written in the past, check out writeups.
