Brute Force Attacks

This is the most common way to get access to your website. Certain attacks refer to the process of entering multiple usernames and password combinations repeatedly until the correct combination has been found.

File Inclusion Exploits

After the Brute Force Attacks, File Inclusion Exploits are the next most common security issue that can be exploited by the attackers.

This takes place when a vulnerable code is used to load remote files. That allows attackers to access your website. Most importantly, a hacker can access the wp-config.php folder on your WordPress website. That is one of the most important files on your WordPress installation.

SQL Injections

Your WordPress website is running a MySQL database. When an attacker gains access to your WordPress database and all of your site data, SQL injections occur.

A hacker will create a new admin user account with SQL injections. This can then be used to log in and access the WordPress website in full. You can also use SQL Injection to add new data, including links to malicious or spam websites, to your database.

Cross-Site Scripting

This vulnerability is most commonly found in WordPress plugins. 84% of all security vulnerabilities across the Internet are called Cross-Site Scripting or XSS attacks.

This works like this: An attacker finds a way to get a victim to load web pages with unsafe javascript scripts. Such scripts are loaded without the knowledge of the user and then used to steal data from their browsers.

An example of a cross-site scripting attack would be a hacked form that appears to be on your website. If the user enters the data into that form, the data would be stolen.


Malware, the short form of Malicious Software, is a code used to gain unauthorized access to a website for the collection of sensitive data.

A hacked WordPress site usually means that malware has been injected into your website files. So, if you suspect malware on your site, take a look at recently modified files.

Malware can be quickly identified and cleaned by either removing a malicious file manually or installing a new WordPress version. Or restore your WordPress site from an uninfected and previous backup.

Outdated Plugins and Themes

If you are not running updated plugins and themes than you are at a risk of an attack. The latest version of plugins and themes comes with security patches and improvements. Make sure you are running the latest version.

Tip: If you are running multiple websites or using many plugins and themes. And you don’t have the time for updating these. In such cases, you can use an auto-update plugin. It can automatically update your WordPress core (major and minor updates), translations, plugins, and themes.

Check out our list of 7 Best WordPress Auto-Update Plugins 2019.

Using Plugins and Themes from Unreliable Sources

WordPress websites can be easily exploited by hackers. If your website code is not well written, or if you use unsafe, outdated plugins from unreliable sources.

Don’t download plugins from any torrent or other unsafe websites. The free version may contain malware and may cost you the security of your website.

Tip: Only download plugins and themes from trusted and secure repositories such as, or premium plugin websites such as ZetaMatic, Kinsta, Envato, etc.

Weak Passwords

It’s one of the biggest security flaws you can easily avoid.

Tip: Use solid password combinations of letters, numbers, special characters for your WordPress admin.

If your password is too hard to remember, write it down somewhere or make a google document.

Using Poor-Quality or Shared Hosting

The server is the first target for hackers since the WordPress site located there. Using poor quality or shared hosting will make your website even more vulnerable.

Shared hosting may also be an issue since many websites are housed on a single server. When one website is hacked, hackers may also have access to other websites and their information.

Tip: Choose a private server to ensure that your website is free from any vulnerabilities.

Follow the above measures and you will be free from any common security issues on your website.

Also, using one of the best security plugins is a great way to add an extra layer of protection that can protect your website from advanced security vulnerabilities. Check out the list below.
