I am a M.S. student @KAIST SysSec Lab. My research interest is to find, analyze, and exploit software and hardware vulnerabilities. Especially, I'm putting my effort into offensive IoT, Embedded, and CPS(Cyber-Physical System) security. And Since 2018, I've been participating in major CTFs as a member of @CyKor.
