There is a world of numbers, hiding behind letters, inside computers that stimulates the brain of Yiannis. Currently, he is focusing on research relating to coding standards, practices and ways of exploiting development code. This focus entails the breaking and making of client-side standalone, as well as server-side web applications.
For OWASP, Yiannis runs the JBroFuzz project, a tool that has had as an objective to provide a stable (cross-platform) functional fuzzing tool for web applications, over HTTP & HTTPS.
He has also contributed bits of code to other projects, such as DirBuster and co-authored a number of articles and publications, including v2 of the testing guide.
