How to Stop DDoS Attacks on WordPress With the Right Plugin

How to Stop DDoS Attacks on WordPress

WordPress is one of the most secure content management systems. Millions of people trust it as their go-to website builder. Still, you shouldn’t ignore security issues such as DDoS attacks if you want to keep your websites up and running.

You can’t leave your public websites insecure, keeping them susceptible to DDoS attacks. Otherwise, all your effort and money will go to waste within seconds before you can even realize it. A powerful attack may result in the prolonged unavailability of a website. Imagine you depend on a website for a living and can’t access that due to a DDoS attack. Sounds terrible, right?

No worries, we know how alarming this issue is. So in this article, we showed how to stop DDoS attacks on WordPress both manually and using a plugin. Before diving deeper, let’s know what is a DDoS attack at first.

What Is a DDoS Attack?

What Is a DDoS Attack?
DDoS Attack

DDoS stands for distributed denial of service. A DDoS attack is a cyber attack that uses a network of compromised computers (also known as botnets). These botnets simultaneously send massive data or numerous requests to a target server.

This sudden overflow of data often exceeds the capacity of the server. It causes websites to slow down or crash due to the overwhelming traffic/data/requests that they can’t handle.

Here’s a real-life example of how a DDoS attack disabled the internet banking facility of HSBC in 2016.

How Does DDoS Affect Your Website?

The effects of a DDoS attack depend on a few variables like how prepared you are, how secure your server is, and how powerful the attack is. The capacity of a server varies in many aspects. So, you can’t set one-formula-for-all when determining how an attack can affect your site. Here’s a list of some common problems caused by a DDoS attack.

Your Website May Shut Down

The most-reported outcome of a DDoS attack is a slow and unresponsive website. If the attack is too strong to handle for your system, the website may shut down at the peak of the attack. You won’t get the site back until you fix the issues.

It Becomes Easier to Hack

During a DDoS attack, everyone focuses on mitigating the attack, while leaving the security system vulnerable. And, chances are high that the attack will weaken the security features of your WordPress website. You need to ensure optimum security for your WordPress site to stay risk-free (almost).

You Will Lose Time & Money

Suppose you have an online store. If it falls prey to a DDoS attack, you will face a substantial loss of money. Customers won’t be able to make orders and existing customers won’t be able to check the order status. Besides, you may need to hire security professionals to mitigate the attack completely. The website will remain down for an extended time if you can’t get it back to work.

Your Brand’s Reputation Will Be at Stake

The visitors and online shoppers can’t enter or log in to your website during the attack. Your support team/customer relation executives may receive hundreds of calls simultaneously if you have a strong customer base. This unavailability of service seriously hampers a brand’s reputation. Customers/visitors may start feeling insecure to shop or get information from your website.

The SEO Health Will Deteriorate

Google bots often crawl through websites to find and index new or updated content. You may lose rank if it comes to your website when the site is unavailable. Even sometimes it takes a few days to get the website back in order.

During this whole time, the affected website usually redirects to a 502 bad gateway. This also affects search rankings negatively. Moreover, any link that points to your website won’t work as well. All these things combinedly will worsen your website’s SEO health.

DDoS Attack Vs. Hacking- Are they Same?

Some people confuse hacking and brute-force attacks with DDoS attacks. Yes, hacking and brute force attacks are other forms of cyber attack. But, it’s different from DDoS.

Hacking refers to taking control of the system and exploiting the weakness in security to gain access to a system or a website. Whereas, DDoS refers to making a website slow or unavailable due to the overflow of traffic sent to the target website.

Bruteforce attack is also one kind of hacking where the hackers try to get the login info by performing trial and error attacks. Hackers try to guess all possible combinations and find out the right login credentials to get access to your website.

Hacking/brute-force attack is more serious in the case of a business website. If a malicious hacker misuses the stored data within your website, it can cause irreparable loss. You may even lose control of the website permanently.

You can use a Security Plugin to prevent hackers from getting easy access to your website.

Why You May Become a DDoS Target

You may wonder why would someone bother to launch a DDoS attack on your website. Some attackers have well-defined goals while some others do it just for fun. Let’s explore the possible reasons.

1. Attacks by Unethical Competitors: You can’t expect all your business competitors to have strict principles. Instead of outperforming you in legitimate methods, some competitors may sponsor DDoS attacks to gain a competitive advantage over you. What’s more disheartening is that you can’t identify the attackers since attackers usually use untrackable IP addresses.

2. Attacks by Followers of a Different Ideology: Suppose you run a website that promotes Black Lives Matter (BLM) movement, a motivated anti-BLM group may DDoS your website to hinder your regular activities. Or, imagine you are a supporter of Donald Trump, someone who is against him may run an attack to put your website out of action. When such attacks happen because of ideology or beliefs, it’s called “Hacktivism”.

Here’s an example of Hacktivism attack, performed by the Anonymous to protest against George Floyd death.

3. Attacks Due to Vulnerability of the Website: People with excellent technical knowledge sometimes do DDoS attacks just for fun, out of boredom. This is nothing but an adventure, a source of recreation for them. Websites with low security and exposed vulnerability are most likely to fall victims to such attacks.

4. Attacks for Monetary Gain: You may become a DDoS target easily if the downtime of your website matters so much to your business. The attacker may run a planned attack to blackmail and ask for ransom money from you.

Ways to Stop DDoS Attack

You can stop DDoS attacks both manually and with the help of plugins. The first process involves a few pieces of coding and the latter requires a highly functional and compatible plugin. We’ve shown both methods in the following sections.

Secure Your Website from DDoS Attack Manually

WordPress is a highly flexible platform that allows third-party integrations using APIs (Application Programming Interface). DDoS attackers take advantage of these APIs. They exploit the APIs to send overwhelming requests to the site. One of the most effective ways to stop DDoS attacks on WordPress sites is to disable a vulnerable API named XML-RPC.

You need this API only to interact with third-party applications. For example, this API allows you to use the WordPress mobile app. If you don’t need this functionality, you can unhesitatingly disable it.

Go to your website’s .htaccess file. Copy and paste the following code to the bottom of the .hataccess file.

#Block WordPress xmlrpc.php requests
<Files xmlrpc.php>
order deny,allow
deny from all
allow from xxx.xxx.xxx.xxx
</Files>

These pieces of code will disable the XML RPC in your WordPress site. Replace xxx.xxx.xxx.xxx with a particular IP address you want to allow to use XML-RPC of the WordPress site.

If you want to avoid the hassle of coding and use a plugin to secure your website, see the following section.

Use Plugins to Prevent DDoS Attacks

You can use a Web Application Firewall (WAF) to identify and block malicious traffic.
