Figure 0x1 – LeakIX
My work focuses on vulnerability research, exploit development, and offensive security engineering.
I started my journey in 2020 with almost no technical background, driven by pure curiosity - and since then, I’ve dedicated myself to breaking, building, and learning every day.
I regularly share my research and tools on GitHub , contributing to projects that help improve the security of systems and applications worldwide.
Here on my blog, you’ll find my technical write-ups, vulnerability analyses, and insights from real-world exploitation and research.
