WordPress powers more than 40% of all websites on the internet. Its popularity also makes it one of the biggest targets for hackers. Every day, thousands of WordPress websites are attacked because of simple security mistakes that could have been avoided.
The good news is that most WordPress hacks are not caused by advanced cybercriminals. Instead, they happen because website owners forget basic security practices such as updating plugins, using weak passwords, or installing software from untrusted sources.
If you own a WordPress website, avoiding these common mistakes can greatly reduce the risk of getting hacked.
1. Using Weak Passwords
Weak passwords are one of the easiest ways for hackers to break into a WordPress website. Cybercriminals use automated tools that can guess thousands of common passwords within minutes. If your password is short or easy to predict, your website becomes an easy target. Always create a strong password using a mix of uppercase and lowercase letters, numbers, and special characters. Using a password manager can help you generate and safely store secure passwords.
2. Keeping the Default Username “admin”
Many WordPress websites still use the default username “admin,” making it easier for attackers to guess the login details. During brute-force attacks, hackers almost always try this username first. Changing it to something unique adds an extra layer of protection. A custom administrator username makes it much harder for automated bots to access your website.
3. Ignoring WordPress Updates
Every WordPress update includes improvements, bug fixes, and important security patches. When you delay updates, your website may remain vulnerable to security flaws that hackers already know about. Cybercriminals often target websites running outdated versions of WordPress. Keeping your website updated is one of the simplest and most effective ways to stay protected.
4. Forgetting to Update Plugins
Plugins add useful features to your website, but they also need regular updates. Developers frequently release security patches to fix newly discovered vulnerabilities. Running outdated plugins gives hackers an opportunity to exploit those weaknesses. Make it a habit to update your plugins regularly and remove any that are no longer maintained.
5. Using Outdated Themes
Your WordPress theme controls the appearance of your website, but it also contains code that can be vulnerable if left outdated. Theme developers release updates to improve compatibility and fix security issues. Ignoring these updates can expose your website to unnecessary risks. Always keep your active theme updated and delete themes you no longer use.
6. Installing Pirated Themes and Plugins
Pirated or “nulled” WordPress themes and plugins may seem like a way to save money, but they often contain hidden malware or malicious code. These files can give hackers full access to your website without your knowledge. Download WordPress products only from trusted developers or the official WordPress repository. Paying for legitimate software is much cheaper than recovering from a hacked website.
7. Installing Too Many Plugins
Every plugin you install adds extra code to your website. While plugins are useful, having too many increases the chances of security vulnerabilities and performance issues. Poorly coded or abandoned plugins can become easy entry points for hackers. Keep only the plugins you truly need and regularly review whether they are still necessary.
8. Not Using Two-Factor Authentication
Two-factor authentication (2FA) adds an extra verification step after entering your password. Even if someone steals your password, they still need the second verification code to log in. This greatly reduces the risk of unauthorized access. Many free WordPress security plugins make enabling 2FA quick and simple.
9. No Website Backup
No security system is perfect, so regular backups are essential. If your website is hacked, infected with malware, or crashes unexpectedly, a recent backup allows you to restore everything quickly. Store backups in a secure location outside your hosting account. Automatic daily or weekly backups provide valuable peace of mind.
10. Using Cheap or Untrusted Hosting
Your hosting provider is responsible for much of your website’s security infrastructure. Reliable hosting companies offer firewalls, malware scanning, server monitoring, and automatic updates. Low-quality hosting services may lack these protections, making websites easier to attack. Investing in trusted hosting improves both security and website performance.
11. Using HTTP Instead of HTTPS
HTTPS encrypts the connection between your visitors and your website, protecting sensitive information like passwords and contact form submissions. Websites without HTTPS are more vulnerable to data interception. Modern browsers also warn visitors when a website is not secure. Installing an SSL certificate is free with many hosting providers and improves both security and SEO.
12. Leaving File Permissions Incorrect
WordPress files and folders should have proper permission settings to prevent unauthorized changes. Incorrect permissions may allow attackers to upload malicious files or modify important website data. Following WordPress-recommended permission settings helps keep critical files protected. Your hosting provider can also help verify these settings.
13. Not Limiting Login Attempts
Hackers often use automated bots to repeatedly guess login credentials through brute-force attacks. Without login attempt limits, these bots can try thousands of password combinations every hour. Limiting failed login attempts blocks suspicious activity and helps protect administrator accounts. This simple feature can stop many automated attacks before they succeed.
14. Not Using a Security Plugin
A WordPress security plugin provides continuous protection by monitoring suspicious activity, scanning for malware, and blocking known attacks. Many also include firewall protection and login security features. While no plugin guarantees complete safety, it significantly improves your website’s defenses. Choose a trusted security solution and keep it updated.
15. Leaving Unused Plugins Installed
Inactive plugins remain on your website even if they are not currently being used. If one contains an unpatched vulnerability, hackers may still exploit it. Simply deactivating a plugin is not enough. Delete any plugins you no longer need to reduce potential security risks.
16. Not Monitoring User Accounts
Every user account with access to your website represents a possible security risk. Old employee accounts, inactive users, or accounts with unnecessary administrator privileges can become targets for hackers. Review user accounts regularly and remove anyone who no longer needs access. Always assign the lowest permission level required.
17. Using Old PHP Versions
PHP is the programming language that powers WordPress. Older PHP versions eventually stop receiving security updates, leaving websites exposed to known vulnerabilities. Updating to a supported PHP version improves both security and website speed. Always check that your themes and plugins are compatible before upgrading.
18. Exposing Sensitive Files
Important WordPress files such as wp-config.php contain database credentials and other confidential information. If these files are publicly accessible, attackers may gain valuable information about your website. Proper server configuration helps protect sensitive files from unauthorized access. Restricting access to these files strengthens overall security.
19. Not Scanning for Malware
Malware can remain hidden on a website for weeks or even months without obvious signs. During that time, it may steal data, redirect visitors, or spread malicious content. Regular malware scans help detect infections before they cause serious damage. Early detection makes cleanup much easier.
20. Ignoring Security Warnings
Security plugins, hosting providers, and WordPress often display warnings about vulnerabilities or suspicious activity. Ignoring these notifications allows problems to grow worse over time. Investigating alerts quickly can prevent malware infections and website downtime. Treat every security warning as something worth checking.
21. Using the Same Password Everywhere
Reusing the same password across multiple accounts is a major security risk. If one website suffers a data breach, hackers often test the same password on email accounts, hosting panels, and WordPress logins. Using unique passwords for every account limits the damage if one password is compromised. Password managers make this much easier.
22. Giving Everyone Administrator Access
Administrator accounts have complete control over a WordPress website. Giving too many people administrator privileges increases the chance of accidental mistakes or account compromise. Most users only need Editor, Author, or Contributor roles. Follow the principle of least privilege whenever possible.
23. Editing Website Files Directly
Making changes directly to WordPress core files can create security problems and make future updates more difficult. A small mistake may also break your website. Use child themes, staging environments, or proper version control when making code changes. Always create a backup before editing important files.
24. Not Protecting the Login Page
The WordPress login page is constantly targeted by automated attacks. Protecting it with CAPTCHA, login attempt limits, or a custom login URL helps block malicious bots. These simple security measures reduce unwanted login attempts and improve overall website protection. A secure login page is your first line of defense.
25. Thinking “My Website Is Too Small to Be Hacked”
Many website owners believe hackers only target large businesses, but that’s not true. Most attacks are automated and scan the internet looking for any vulnerable website, regardless of its size. Personal blogs, small business websites, and hobby sites are attacked every day. Every WordPress website should follow good security practices, no matter how much traffic it receives.
