Thanks for the link, had not seen Uplink before. It's not what I was trying to remember though. I'm basically talking about a website. On the first screen it has a username and a password box. The password check is hardcoded into the JS on the page and viewsource gives it to you. Completing it gets you to the next stage. The next stage has no such info, but the password is easily guessable. The one after can be beaten by a cookie modification, the one after that involves injecting some variables into a server-side script etc etc... At each stage it links you to articles which may be relevant tothe task at hand; It's like a step-by-step training to hacking websites, graded nicely in difficulty from the trivial up to some reasonably difficult techniques at the higher stages.
