In this "attack" the URL was incremented by one. I've written a lot of loops, and incremented a lot of numbers, and none of them have ever become properly escaped XSS exploits, or malformed YAML, etc. If your bar for "hack" is so low that we're training pre-schoolers to accomplish it, it may lack all descriptive power.

Imagine you're reading a story at example.com/stories/bears-part_1_of_3.html and just as it gets good, it's done. Without so much as a "The End". Do you sit dumbfounded, or do you hack the bejeezus out of the website? See how silly that sounds. So lets just say you "went to the next page".
