Get out, then anonymously warn the appropriate financial authority/regulator. Optionally, and if it's safe for you and for them, you might want to anonymously warn the employees like yourself, but this might be impossible or unwise.

Consider that someone else may already be planning to warn the authorities. To avoid or minimise involvement in any legal issues yourself if the company goes down, you should be able to prove you were either naive (very difficult) or had misgivings -- in which case you may need to demonstrate intention to act.

You've already written this post, so if you can prove authorship that would be good. An encrypted string in your profile, perhaps.

As others have said, you really need to talk with a lawyer.

The reasons I suggest this course of action: be the change you want to see in the world. You'll feel better about yourself. God knows what this organisation is actually doing; you were a naive cog in the machine but you're no longer naive, and you don't need that responsibility on your mind.

Finally, regardless of your actions, you should think about how your CV/résumé reflects the time you've spent at this company. Don't hide the truth, but of course don't flat-out divulge everything.
