Understanding Brute Force Attacks

Brute force attacks are a common security issue where attackers attempt to gain unauthorized access to your website, FTP (File Transfer Protocol), and WordPress hosting accounts by trying a large number of username and password combinations. It’s essentially a trial-and-error approach where automation is used to systematically guess login credentials. This method relies on persistence and computing power rather than exploiting specific vulnerabilities or using malicious code.

They work by the attacker identifying a login page or authentication point and then begin credential generation. They use lists of common words, phrases, usernames, and leaked passwords from other breaches. This is the most common method because many users choose weak passwords. They may also combine dictionary words with numbers and special characters.

Using scripts or specialized software, these credentials are rapidly submitted to the target system. This process continues until a valid combination is found or the attacker gives up. There are several types of brute force attacks:

1. Simple Brute Force: Systematically trying every possible combination of characters.
2. Dictionary Attacks: Using a list of common words or phrases as potential passwords.
3. Hybrid: Combining dictionary words with numbers and special characters.
4. Reverse: Starting with a known password and trying it against multiple usernames.
5. Credential Stuffing: Using stolen username/password pairs from other breaches.

Once they have gained access to your website and accounts, the consequences can potentially compromise your entire website. A compromised site can lead to a loss of trust from users and search engines. Search engines penalize or delist unsafe sites, reducing your overall SEO (Search Engine Optimization) ranking and visibility.

Sensitive information like user data or financial records could be stolen. Attackers may also insert malware that damages your site and infects visitors’ devices. This can lead to financial losses from theft or indirect costs from business disruption, for example if you are running an e-commerce site and website disaster recovery. Depending on the nature of the breach, you may face legal consequences for failing to protect user data.

Why WordPress is Vulnerable

WordPress powers a vast portion of websites globally, giving attackers a large pool of potential targets, and the similar structure across them allows attackers to reuse their tactics more broadly. The open-source nature of WordPress also allows attackers to study the code and identify vulnerabilities.

The extensive use of plugins creates a wider attack surface, with potential flaws existing in any installed plugin. Furthermore, many users lack the technical expertise to properly secure their WordPress installations, often leaving them with default settings that increase risk.

Common Security Weaknesses

Many WordPress users choose weak passwords, making them vulnerable to brute-force attacks where attackers systematically guess login credentials. Outdated software, including the WordPress core itself, themes, and plugins, leaves known vulnerabilities unpatched and exploitable. Insecure third-party plugins and themes, especially those poorly coded or abandoned by developers, can introduce new security flaws.

Improper file and directory permissions can expose sensitive areas of a WordPress site, granting unauthorized access to attackers. If enabled and not secured, the XML-RPC feature can be exploited to amplify brute-force attacks.

Additionally, default WordPress installations might reveal version numbers and user information, inadvertently aiding attackers in targeting specific vulnerabilities.

Default Settings Increase Risk

The default “admin” username is a common target due to its predictability along with standard login page URLs like “/wp-admin” or “/wp-login.php” because they are visible by default. WordPress also allows unlimited login attempts by default, facilitating brute-force attacks.

Leaving XML-RPC enabled without proper security measures opens another avenue for exploitation. Default file permissions might be too permissive in some WordPress hosting environments, granting unauthorized access.

Displaying the WordPress version by default helps attackers target specific vulnerabilities in older versions. Finally, the ability to easily discover valid usernames through author pages or the REST API can help with targeted attacks.

WordPress Brute Force Attack Protection Steps

By taking the following steps, you significantly reduce the risk of successful brute-force attacks on your WordPress site. These create multiple layers of security, making it much more difficult for attackers to gain unauthorized access.

Strong Password Policies

Make strong passwords mandatory. Enforce minimum password lengths (ideally 12 characters or more) and require a combination of uppercase and lowercase letters, numbers, and symbols. Disallow usernames from being the same as passwords and avoid the default “admin” username. Consider implementing a password manager to help users create and store strong, unique passwords for all their accounts.

Enable Two-Factor Authentication (2FA)

Two-factor authentication adds an extra layer of security. 2FA requires a second verification code, typically sent to your phone via SMS or generated by an authentication app, in addition to the username and password. Even if an attacker cracks your password, they won’t be able to access your site without the additional code. Many popular WordPress security plugins offer built-in 2FA functionality.

Limit Login Attempts

Limit the number of consecutive failed login attempts allowed before temporarily locking out the IP address. This helps mitigate brute-force attacks by preventing attackers from repeatedly guessing passwords. You can configure the number of allowed attempts (ideally around 3-5) and the lockout duration (consider starting with a short duration like 15 minutes and increasing it for repeat offenders) to find a balance between security and user experience. If a legitimate user gets locked out accidentally, they should be able to regain access after a waiting period or by contacting you.

Change Default Login URLs

The standard login URLs like “/wp-admin” or “/wp-login.php” are well-known by attackers. Changing these URLs to something less predictable makes it more difficult for automated scripts to target your login page. Many security plugins offer this functionality, or you can do it yourself by editing your WordPress core files, though this requires caution and can be overwritten during updates.

Implement Regular Updates

Outdated software often contains known vulnerabilities that attackers can exploit. Regularly update your WordPress core installation, themes, and plugins to ensure they have the latest security patches. Consider using a security plugin that can automate updates for you, saving you time and ensuring your site is always protected with the most recent fixes.

Firewalls and Security Plugins

One of the most effective measures to protect your WordPress site is by installing firewalls and security plugins. These plugins are designed to filter out malicious traffic before it even reaches your server. They limit login attempts and can automatically detect and block IP addresses engaged in suspicious activities. Wordfence is a highly recommended choice, offering a comprehensive firewall and real-time monitoring capabilities. It helps in detecting and blocking brute force attempts before they can do any harm.

When configuring these security plugins, it’s crucial to ensure that each is set up correctly to maximize its protective capabilities. Regularly update the plugins to protect against the latest threats and conduct thorough audits to ensure all security features are optimized.

SSL Certificates

Secure Sockets Layer (SSL) encrypts communication between your website and visitors’ browsers. This safeguards sensitive data, such as login credentials and credit card information, from being intercepted by attackers. Having an SSL certificate ensures a secure connection and is often denoted by a padlock symbol in the address bar. Many web hosting providers offer SSL certificates with their plans, or you can obtain one from a security vendor.

IP Blocking and Whitelisting

You can use IP blocking to restrict access to your login page or entire website from specific IP addresses that have exhibited suspicious activity. Conversely, whitelisting allows access only from trusted IP addresses, such as your office or home network. This can be particularly useful if you manage your site from a specific location. There are plugins available that offer IP blocking and whitelisting features.

Best Practices for WordPress Security

Even with the above security measures, unforeseen events can happen. Here are some WordPress security best practices for ongoing maintenance to ensure your WordPress site remains secure and recoverable.

Regular backups are crucial for disaster recovery. Create scheduled backups of your entire WordPress installation, including the database, themes, plugins, and files. Store these backups securely offsite, such as in a cloud storage service, to ensure they aren’t affected if your web server is compromised.

Monitor your website for suspicious activity. Security plugins can log login attempts, track changes made to files and themes, and monitor for malware. Regularly review these logs to identify any potential security breaches. Following that, assign user roles and permissions carefully and only grant users the access they need to perform their tasks.

Only use plugins that are essential for your website’s functionality. Deactivate and delete any unused plugins to reduce the potential attack surface and test updates on a WordPress staging site before applying them to your live site. Regularly scan your website for vulnerabilities using security plugins or online scanners.
