M3str3/README.md

Hello, I'm Mestre

Cybersecurity enthusiast. I break things; sometimes I even fix them. You’ll probably find me at the coffee machine complaining about Java.

I sometimes use GitHub as my personal cloud. If my repos look random or borderline chaotic, take them as proof of ongoing (slightly unhinged) experiments.

Yes, I like Rust.

Some things I’ve built (I rarely update this. Fair warning.)

Project What it is Notes
HexSpell Executable parsing library for Rust Zero external deps, minimalist approach
Void Loader PoC of a “Cavity Fractioned Loader” (Black Mass Vol.1) Loads fractionated binaries directly in memory
RootCause SAST Scanner Rough, good for learning
Ransomware Full-operation simulation (blog, server config) Built for research & defense

Wanna connect? (Most → least formal)
