This hack was related to accessing skills available to a select number of champions. They are disabled in that they were not accessible through key bindings, but in advertently left in code and accessible to anyone that spent enough time digging. It was only found on champions that had skill re-works through out the years, Ryze being one of them.
This has been patched.
Much like the recent gold hack that was related to selling your runes ingame for gold, it was merely a bit of oversight by riot in that believing people wouldn't be able to access things simply because they shouldnt know about them.
