There are two considerations here--company policy and workplace politics. Familiarize yourself with the company policy on reporting unethical/illegal activities by either consulting the employee handbook or human resources. Your company should have a code of ethics. If you go to HR, ask them about the policy, you don't have to go into specifics.
With that being said, understand that workplace politics can get sticky when you speak up, especially if you confront your boss directly. The other side is you could find out that you're misinterpreting your boss's actions and earn his respect for being a vigilant team member. Whatever you choose to do, act in the best interest of your employer while ensuring that you are legally covered. I hope this helps and that things come to a productive resolution for you and your employer.
