Evan Ricafort

About Me

I am Evan Ricafort, A bug hunter from the Philippines interested in Web Application security vulnerability testing. I was born in the Province of Ipil, Zamboanga Sibugay, Philippines on January 3, 1996. Studied Computer Networking at Ateneo De Zamboanga University. I'm a Security Researcher at Invalid Web Security, A startup security firm based in the Philippines. Since mid of 2013 I've been an active bug hunter in the bug bounty community reporting multiple different kinds of security vulnerabilities on popular websites such as Microsoft, Google, Twitter and etc. I spend my off-hours playing video games and riding bikes.
