Remove & Disable XML-RPC Pingback

Prevent your WordPress site from participating and being a victim of pingback denial of service attacks. After activation the plugin automatically disables XML-RPC. There’s no need to configure anything.

By disabling the XML-RPC pingback you’ll:
* lower your server CPU usage
* prevent malicious scripts from using your site to run pingback denial of service attacks
* prevent malicious scripts to run denial of service attacks on your site via pingback

From sucuri.net:

Any WordPress site with Pingback enabled (which is on by default) can be used in DDOS attacks against other sites.

Why Not Just Disable XMLRPC Altogether?

Yes, you can choose to do that, but if you use popular plugins like JetPack (that use XMLRPC) then those plugins will stop working. That is why this small plugin exists.
