About Me
Contents
Introduction Link to heading
I’m Jing-Ping Yu (hicat0x0), currently a graduate student in the Master Program in Information Security (MPIS) at National Taipei University of Technology. I received my B.S. in Computer Science and Information Engineering from National University of Tainan in 2026.
My work centres on offensive and defensive security, wireless communications and SDR, cloud and virtualisation systems, and forward-looking topics such as quantum computing. During my undergraduate years I was active in the Taiwanese security community and in CTF competitions, building hands-on experience in vulnerability analysis, reverse engineering and system defence.
I like turning the concepts I read about into something that actually runs, and I use this blog to record technical notes, CTF write-ups and the things that went wrong along the way.
