I'm André Baptista

I just completed my MSc in Information Security @ University of Porto. I've always loved hacking stuff and security CTFs are my supper. In April 2015 I joined xSTF, a CTF team from the University of Porto, in which I am now captain. Since then, we've been spending weekends in the University pwning binaries, eating massive pizzas and drinking some beer. Currently, I'm a researcher at INESC TEC and I also contribute to C3P (Center of Competence in Cyber Security and Privacy) @ University of Porto. I love reverse engineering and exploitation.
