I participated in the 2016 CSAW CTF (https://ctf.csaw.io). Here are some results.

In 2016, I participated in NYU's Cyber Security Awareness Week Capture the Flag event.

• Notesy 2.0 - for 1 point, enter the flag given in the problem description.
• Coinslot - for 25 points, write a small script solving the change-making problem.
• Sleeping Guard - for 50 points, break the encryption on a PNG file.
• Regexpire - for 100 points, write a small script that can create strings that match a given regex.
• mfw - for 125 points, find and exploit a vulnerability in a PHP website.
