A good concise beginners' tutorial. Needs to be followed up with a more in-depth one, though.
By the way, I'm a rather picky person when it comes to tutorial quality and I don't think I could find anything wrong with this one.

I'm planning on writing a more in depth one that focuses more on prevention. Executing the attack is relatively easy, but the prevention (encryption token patterns, referrer headers etc) is actually pretty hard to understand on a beginner level.

Thank you for the kind words
