Simple hack? player.setAV Chameleon 100, then sneak into bank vaults. Having once worked at a bank I know the procedures and would simply follow behind the tellers, pickpocket their keys, then help myself---maybe firing a gun at the wall to scare the shit out of everyone so I'd have the additional cover of chaos.
More complicated hacks? I'd give myself the ability to read the complete state of the world, so basically everyone would be walking around with a little spreadsheet of vital information (disposition toward me, current wealth, desires, intelligence/strength/whatever else I could think of)---a cheat sheet to how to manipulate, influence, and/or steal from them.
I'd use my powers for pure Chaotic Neutral. It's not that I'm actively evil, it's that I'd only be in it for myself, morality be damned. I'd do some good (most of it in the form of making every government official think he had voices in his head, thus spooking them out of corruption), I'd do some evil (robbing banks), but it'd all be self-interest.
