Hi, I’m Yannie — a cybersecurity learner documenting the process of turning curiosity into practical security skills.

This site is my digital lab notebook. I write about ethical hacking, penetration-testing labs, CTF challenges, web and system security, and the security questions emerging around AI and large language models.

What you’ll find here

• Walkthroughs that focus on the reasoning behind each step
• Notes from hands-on labs and CTF challenges
• Security tools, commands, and techniques worth remembering
• Mistakes, failed approaches, and what they taught me
• Experiments in AI and LLM security

You can find my projects and ongoing work on GitHub.
