Hi! My name is Rui (a.k.a. ruifi47) and I’m a 23yo student from Porto (🇵🇹 Portugal), currently finishing my MSc in Information Security @ University of Porto. My interests span across a wide range of fields within information security, with a particular focus on the offensive aspect.

I actively participate in CTF competitions as a member of xSTF or ransoware. For now, in this blog, you can find writeups for some CTF challenges I’ve previously solved. Also you can check the CTF-solves repository in my github, for a collection of solutions of more CTF challenges that I’ve pwned.

Hopefully you can learn something new! 😄
