radare2 is a very cool set of tools that you probably don't know how to use! Let's go through a simple exploit CTF challenge to understand how to use it for exploit development.

We'll be focusing on "ropasaurus rex" which is a simple challenge from Plaid CTF After checking out the latest and greatest radare from git, let's get started!

Open up ropasaurusrex in r2 and call analyze on the binary. We can list the functions with "afl"
