If you aren't directly editing core files the system source is the same as what's publicly available anyway? According to the license page providing the source only applies to derivatives of the original work. If you modify core files you have to open source your core modifications (only), which makes sense if you think about it. You never have to give out the source to your application. I made a mistake earlier the app folder is not under AFL the config folder is.

Only the Source Code of the Original Work or the Source Code of a modified (altered, etc.) Derivative Work must be disclosed.

I don't see a problem with a notice that a site is powered by CI, you don't have to list the version. The only hack I've seen was an SQL injection on a old classic ASP site that was inherited. All they did was add links to every page to mess with Google. If you use a payment gateway and prevent SQL injections you aren't a priority. If bot's can't inject link spam into your pages and human's can't steal financial info there's better targets out there. Even CSRF is highly unlikely.
