Notes from my journey into cybersecurity, penetration testing, and the mindset behind breaking systems to secure them.

From Day Zero to Zero Day

My physical copy of Eugene Lim's From Day Zero to Zero Day arrived today. I came across the book on LinkedIn, looked into it, and quickly realized it fit very well with the study path I am building. What stood out immediately is how practical and technical it seems. It…

IDA-Style Highlighting in VS Code

As I work through Zero Day Engineering training, I have been spending more time reading large open-source codebases from a vulnerability-research perspective. One small thing I kept missing from IDA Pro is the highlight feature: select a token, and instantly see the other matching occurrences nearby. It is simple, but…

From Firmware to Full Systems: Why I'm Studying Penetration Testing

I've spent years working with embedded systems in a security context, and I love it. There's something uniquely satisfying about exotic architectures, soldering (or occasionally releasing the magic smoke when things don't go as planned), and the bridge between software and the physical world. Watching systems break in completely unexpected…
