What is this?
This is inspired by a type of contest from information security called Capture the Flag, where participants solve increasingly difficult challenges. This version is mostly tailored towards a Web Developers skillset (and easier than traditional CTFs).
The challenges require you to think outside the box, inspecting and tampering with the HTTP request/response and so on. This is not a regular quiz.
All challenges are worth points and progress is tracked. This is the reason I require you to log in, and no other data than your username and results are stored.
