Restricted Ruby - A CTF story

by Rosa

Published January 26, 2017 in Technology

It's not common to find Ruby problems in security CTF (Capture The Flag) competitions, but luckily there are some out there. These type of problems are always a great opportunity to learn some Ruby internals or features of the language that aren't usually known. They are also a perfect excuse to do crazy things and get as creative as possible. In this talk I'll present some problems from the CTF organised by a famous Japanese security group in 2016 and some ways to solve them.
