zip_url from the problem endpoint, download the ZIP file. Inside, among other things that you can rummage through, is a file called
secret.txt which contains the solution to this challenge. But the ZIP is password protected, and I'm not giving you the password.
The password is between 4-6 characters long, lowercase and numeric. ASCII only.

Go! Use the force!
Problem JSON will contain only one key:
zip_url: the one-time URL for the ZIP file you'll need to brute-force
Solution JSON structure:
secret: the secret value you found inside the
