You get well paid and it's legal.
The reality is that you don't get paid well if the data is worthless. You only get paid well when the data is worth orders of magnitude more than what you're being offered. If you are inclined to break that law, that's a pretty nice carrot dangling there.
If you are so inclined, why wouldn't you take the job and report the not so crafty exploits to bring in the sweet, sweet paycheque and use the really juicy exploit to also go after the even sweeter data? It's a total win-win situation...
...unless you get caught, but if you are so inclined that's not exactly on your radar.
