About Me

By 0xh4ty

Welcome

I’m 0xh4ty. I work in security and spend most of my time understanding how systems break and why.

This blog documents what I learn, from web application vulnerabilities to reverse engineering Linux binaries and exploring blockchain systems.

How I Got Here

I started in Web2 security and spent two years building fundamentals in penetration testing and web exploitation. During this time, I earned the HTB Certified Web Exploitation Specialist (CWES) certification and developed a strong grounding in vulnerability classes and exploitation patterns.

I am currently pursuing a Master of Computer Applications (MCA) while continuing to deepen my focus on systems and security research.

Over time, I became more interested in how systems work internally. That led me toward blockchain technologies, Rust, and lower-level program analysis.

What I Work On

My recent work includes:

• Reproducing real-world smart contract vulnerabilities
• Writing exploit proof-of-concepts
• Reverse engineering C++ binaries using Ghidra and GDB
• Contributing to compiler-adjacent Rust tooling
• Building a Solidity language server for Emacs
• Building the Rust-based static site generator that powers this blog

I prefer understanding systems deeply rather than treating them as black boxes.

Tooling

Linux is my primary environment and Rust is my main language. Emacs is my primary editor and workflow hub.

Current Focus

I am currently focused on reverse engineering, vulnerability discovery, and strengthening low-level systems intuition through Rust and C++.
