Well, a majority of my hacks are altering the naming conventions in the software… i.e; renaming wp-content, wp-content/plug-ins, and wp-includes. I don’t really know how to patch that with a plug-in.
Nothing against WP, but I prefer the world to not know my site is on the WP platform. I’m just anal about security, and it seems hackers have it out for exploiting WP sites when they find a hole in the platform. They are patched pretty quickly, but I prefer to reduce the visibility of WP on the forward-facing aspects of my site.
