Simple plugin that disables XML-RPC, since it is enabled by default on WordPress 3.5 and above. It also removed references in the headers and in the body of the html.

Disable XML RPC Fully

This plugin disables the Pingback functionality in your blog.
If a request tries to use the pingback method, they will get an error:
“server error. requested method pingback.ping does not exist.”
Note: Disabling pingbacks means you will not receive notifications when other blogs link to your content.
