I’m hikaro — a reverse engineer working primarily in C, C++ and x86/x64 assembly. I take apart binaries for a living and for sport: malware, kernel drivers, anti-cheat, firmware, obfuscated commercial software, occasionally my own bugs.
My instinct is to follow control flow down to the instruction that actually matters and then write down what I learned in a form a stranger can pick up cold. That’s most of what this site is — public artifacts from that process.
Outside of binaries, I read a lot of papers on exploit mitigation, fuzzing, and program analysis, and play CTFs with friends. Reverse engineering taught me to trust nothing and verify everything; that habit bleeds into the rest of my work.

Static + dynamic analysis of commercial protection layers. Focus on syscall hooks, integrity routines, and the boundary between user and kernel checks.
Extracting and rehosting embedded bootloaders, mapping memory layouts, and reasoning about secure-boot chains in real hardware.
Modern mitigations are interesting precisely because they shape the technique. I document each primitive end-to-end so the reasoning carries over to the next target.
Long-form writeups are the artifact — they exist to make the next engineer faster, not to perform.
