1This challenge's flag is sealed in a high-security flag vault protected 2by an atmega32u4 micro-controller. 3 4The only way to unlock it is to enter the correct pin '13371337' into 5the physical access-control panel at the conference. There's just one problem.. 6the button for entering the '3' digit recently broke! 7 8Surely a talented hacker such as yourself can find another way in. 9 10To help you out a little, I even managed to get my hands on the 11source code from the manufacturer.
