On average, hackers break into more than 30,000 websites every day, and many of these are WordPress-powered websites with no essential security measures in place. Since WordPress remains on top of the list of the most popular content management systems and powers nearly 42% of the web, the platform has always been a constant target for hackers. But there’s no need to panic!

When you’re trying to protect your WordPress site from hackers, the very first step you can take is using the best WordPress security plugins. Even though WordPress security goes far beyond just plugins, they’re still an essential tool for protecting your website from various security threats.

Can WordPress be Hacked?

The truth is that WordPress is a pretty secure CMS that is audited regularly by a troupe of 50+ security experts, including lead developers and researchers. Whenever a new vulnerability is discovered, the team releases patches and updates. Yet, nothing can ever be 100% safe, and WordPress is no exception!

According to an infographic, the most common entry points for WordPress sites are:

  • 41% through hosting vulnerabilities
  • 29% via an insecure theme
  • 22% via a vulnerable plugin
  • 8% because of weak passwords

Thus even though the WordPress core is very secure, the use of third-party themes, plugins, and services makes your site vulnerable to hacking attempts. However, using at least one WordPress security plugin, you can protect your site from malware, brute force attacks, and hackers.

The Most Common Types of WordPress Cyber Attacks

So, what could happen if you don’t take WordPress security seriously and do nothing to secure your site? As you may already know, a lot. The most common types of cyberattacks on WordPress sites are:

  • Brute-Force Login Attempts Brute Force Attacks on the login area
  • Distributed Denial-of-Service (DDoS) Attacks
  • Cross-Site Scripting (XSS)
  • Database Injections
  • Backdoors
  • Phishing
  • Hotlinking
  • Defacements
  • Ransomware
  • Malvertising
  • WordPress SEO Spam
  • Malicious Redirects
  • Manual attacks, typically on WordPress eCommerce websites

Again, all these cyber attacks occur due to security loopholes in third-party themes, plugins, and services. They may also happen if you use an outdated version of WordPress and PHP.

What Happens When Your WordPress Site Gets Hacked?

A security breach on your WordPress site can cause severe damage to your online business, including but not limited to:

  • Hackers can steal or hostage your data
  • You can lose access to your website’s admin area
  • Hackers can use your website to distribute malicious code to irrelevant users
  • Theft of confidential information and data belonging to your customers
  • A surge in the number of errors on your website. The most common ones are WordPress 404 Errors, Error Establishing a Database Connection, Parse Error: Syntax Error Unexpected, 503 Service Unavailable Error, and WordPress White Screen of Death Error.
