Magento, checking core files for credit card skimming

Hey guys,

Does anyone know what core files a hacker (using a web shell) would need to modify in Magento in order to skim credit card information from the checkout process?

So far the only file I can see that would allow this is core/Mage/Checkout/controllers/OnepageController.php but I just want to make sure there's nothing else.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

It would most likely be the payment processor code. If you're using Paypal, check the app\code\core\Mage\Paypal\ files.
