Cybersecurity researcher documenting what breaks, what works, and why. Purple team track. CachyOS daily driver.

I'm Muzasio — a cybersecurity researcher and Linux enthusiast working toward a career in purple teaming. I write about what I actually run into: system debugging, security tooling, OSINT workflows, AI experiments, and pentesting methodology. Everything gets documented and published. Stack: CachyOS (Arch), Python, Bash, KVM lab. Currently building toward purple team roles through hands-on labs, tool development, and public research. Find my work at muzasio.hashnode.dev — GitHub scripts, breach teardowns, and dev-logs all live there.
