I'm Andy.
I break things
to fix them.

I'm a cybersecurity professional based in Taiwan, focused on threat analysis, network security, and helping organisations build more resilient systems. With years of hands-on experience in the field, I've worked across penetration testing, incident response, and security architecture.

This blog is where I document what I learn — whether that's a CTF writeup, a deep-dive into a new exploit technique, or practical guides on hardening your infrastructure. My goal is to make security knowledge accessible without dumbing it down.

When I'm not hunting vulnerabilities, I'm building tools, contributing to the security community, and staying ahead of the ever-evolving threat landscape.
