<p>This plugin does more than just using the <code>xmlrpc_enabled</code> hook, because that is only used “To disable XML-RPC methods that require authentication”.</p>
<p>Activating this plugin will also disable pingbacks, trackbacks, and Really Simple Discovery (RSD), because these rely on XML-RPC.</p>
<p>It works with any webserver, because it does not use the .htaccess file.</p>
<h4>Testing the plugin</h4>
<p>From the command line you can test if the plugin is working correctly using <a href="https://curl.haxx.se/" rel="nofollow ugc">cURL</a>. Replace the <code>example.com</code> link to match your website:</p>
<pre><code>curl -d '<?xml version="1.0"?><methodCall><methodName>system.listMethods</methodName><params><param><value><string/></value></param></params></methodCall>' https://example.com/xmlrpc.php
</code></pre>
<p>This should only return the following methods:<br />
– <code>system.multicall</code><br />
– <code>system.listMethods</code><br />
– <code>system.getCapabilities</code></p>

<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>

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

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.
