Security researcher with a deep passion for finding and responsibly disclosing vulnerabilities. I spend my time hunting bugs, playing CTFs, and building offensive security tools.
My focus areas include malware development, malware evasion, C2 red teaming and reverse engineering. I believe in learning by doing — most of what I know came from breaking things.
When I'm not hacking, I'm writing about it. This site is where I document my research, share CTF writeups, and track my CVE disclosures.
