Level 11 of the OverTheWire Natas wargames is a good one. It wasn’t one that could instantly be solved either. It involved programming, encryption, and HTTP. All fun! It started with a dialog to set the background color. When you click the “Set Color” button, it sets a cookie in your browser. But as the dialog says, the cookie is protected. I looked at the source code, as I always do.
