About @d3bo

I’m passionate about cybersecurity, especially the offensive side. I like to understand how things work on the inside and find ways to break them, and the more I learn, the more I realize how much I still have to discover.

In my free time I like to dig into pwn challenges. Binary exploitation hooks me because it forces me to understand in detail how programs work, and I always end up learning something new.

I’ve been writing on my blog, https://d3bo.eu, for a few years now, where I publish writeups, notes and things I learn along the way.
