Welcome! You've joined the How To Hack and Defend Your Website Capture the Flag exercises. Here's how it works: try to solve each exercise and you'll receive a link to the next exercise. Your goal is to get to the last exercise and submit the answer to it.
Exercise instructions are purposefully a little bit vague, but they all involve web app hacking in some way and each page will have a hint if you get stuck. Good luck and happy hacking!-Alejandro
