Okay, first let’s understand what exactly is happening in this challenge.
We as a client are connecting to a server. The page on this server we are accessing allows us to submit a static score as our final score. The goal of the challenge is to figure out how to change that value to the desired ‘high score.’
So here are some questions that you should ask yourself, and find solutions to, as the hacker:
1. Where is this score being sent?
2. How is the score being communicated to that page?
3. How can I implement alteration of that data or change something in that communication channel to achieve the desired goal?
Once you have completed this, you should complete the challenge.
