Biography

🔐 Open to new opportunities

I’m currently exploring new opportunities in cybersecurity and information security, with a particular interest in security research, security engineering, and related roles.

If you know of an opportunity that might be a good fit, I’d be happy to hear from you. Feel free to get in touch.

Ongi etorri! My name is Alberto Fernández-de-Retana. I’m a security researcher with a particular interest in web security/privacy, as well as browser-related stuff. I also enjoy participating in CTF competitions, where I go by the nickname bubu. I’ve also designed challenges for several well-known CTFs, such us CrewCTF and the ASIS CTF Finals. When I’m not doing security research, I enjoy being a pizzaiolo.
