Protect Your Site from WordPress Brute Force Attack via XML-RPC

WordPress is an open-source and widely used CMS platform to start a website of any kind. It may be a Fitness, eCommerce, Blogging, Online Store, Job Board, Forum etc. It is much flexible, easy to use, easy to customize and reliable platform. You can easily come up with almost 19 type of different sites with wordpress. But the one of the biggest issue with wordpress is “Security” which is also the most major con of wordpress. It needs robust security measures to make it vulnerability free.

If you are on wordpress, you need to take care of your site security seriously. You should apply all the necessary security measures to protect it from being hacked (in other words from hackers). Recently, Sucuri online site security services provider founded one of the dangerous wp vulnerability that called “Brute Force amplification attack via XML-RPC”.

Wordpress Brute Force Attack via XML-RPC

In XML-RPC attack, hackers try hundreds of passwords in a single request to guess the password of WP based site. It’s really weird, isn’t it? This password finding approach help hackers to find the confidential data of wp site within a very short time if the site owner is not blocking multiple authentication attempts per XML-RPC request.

What is XML-RPC?

XML-RPC commonly used for communicating between external services and the site contents to modify or access it. If you are a WP user, I am sure you will know Jetpack plugin that uses this protocol to make it work fine. The other example of XML-RPC uses is pingbacks. You can completely disable this protocol but plugins and services like Jetpack will not work.

Further more;

XML-RPC is a simple, portable way to make remote procedure calls over HTTP. It can be used with Perl, Java, Python, C, C++, PHP and many other programming languages. WordPress, Drupal and most content management systems support XML-RPC.

What is WordPress Brute Force amplification attack via XML-RPC?

I am not a wp security guy, so I will not go in-depth of this security issue. In simple words, trying hundreds or even thousands of passwords to guess the WordPress site passwords/login info in a single request is called “Brute Force amplification via XML-RPC“. It is like DDoS attack or something similar.

 How to Protect XML-RPC from WordPress Brute Force Attack?

There are some magnificent security wordpress plugins available in the WP repository that can be used to fix this issue, and the good thing is they are free. I am using iThemes Security plugin formerly knows as Better WordPress Security to keep my site safe.

Look for “Multiple Authentication Attempts per XML-RPC Request” option and simply choose Block(Recommended) option.

Now you have successfully fixed XML-RPC attack issue from your site and you are safe. The one more most important thing is you should always update your security plugin whenever updates available. Because updates always created for improving the performance of plugins/softwares. Further more, I would like to recommend is you must subscribe to some wordpress security providers blog newsletters.
