Name

Hyilim Kim (h1ghl1kh7)

I dived into information security study through STEALTH, a club at Korea Digital Media High School. I mainly focused on system hacking and reverse engineering as my main areas in CTF and research. I live in the terminal — Neovim, Fish shell, and tools that reward depth. I’m playing CTF as h1ghl1kh7. Now, as a researcher at ENKI Whitehat, I’m deepening my vulnerability research while expanding my foundations in computer science at KAIST, with the vision of “making everything work seamlessly.”
