<p>Prevent your WordPress site from participating and being a victim of pingback denial of service attacks. <strong>After activation the plugin automatically disables XML-RPC. There’s no need to configure anything.</strong></p>
<p>By disabling the XML-RPC pingback you’ll:<br />
* lower your server CPU usage<br />
* prevent malicious scripts from using your site to run pingback denial of service attacks<br />
* prevent malicious scripts to run denial of service attacks on your site via pingback</p>

<h4>Why Not Just Disable XMLRPC Altogether?</h4>
<p>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.</p>


Remove & Disable XML-RPC Pingback

Great plugin, super easy to install and just sits there doing it's job. Very light as well, so has no effects that I could see, on site speed or memory usage. Can't think of a reason why you wouldn't be using this to be honest. Thanks for developing it!

Just what I needed

Prevent pingback, XML-RPC and denial of service DDOS attacks by disabling the XML-RPC pingback functionality.
