I’m Kwangyun Keum — a Red Team Operator and security researcher focused on offensive tooling, endpoint evasion, and adversary emulation.

This site is where I publish write-ups on the techniques I build and break: malware development, AV/EDR evasion, Active Directory attack paths, phishing tradecraft, and web application exploitation.

Focus areas

  • Offensive tooling — shellcode loaders, payload obfuscation, IAT/string obfuscation
  • Evasion — AMSI, Windows Defender, and EDR bypass research
  • Adversary emulation — red-team operations and detection engineering
  • Web / AppSec — vulnerability research and disclosure

Elsewhere

Everything here is for authorized security testing, research, and education.
