Defeating baby_rop with radare2

In order to content the people that wanted something less hand-holding than this writeup which they say is too detailed and this one not enough, we decided to write this blogpost: not too short, not too long, and about pwning! The binary was a challenge (called baby_rop) from a small CTF that took place in France, called the sthack. As always, if you don’t get a command, append ? to it to get documentation.
