Use Strong, Unique Passwords, and 2 Factor Authentication (2FA)

A strong and unique password is the first line of defense against unauthorized access to your WordPress website. Avoid using common passwords or easily guessable combinations. Instead, create complex passwords that include a mix of uppercase and lowercase letters, numbers, and special characters. Additionally, consider using a 2 factor authentication to secure your WordPress backend, especially for all Administrator users. 

Tip: Most of WordPress security plugins such as WordFence or Solid Security (previous iThemes Security) support 2FA, so activate, setup, and use it.

Limit Login Attempts

Limiting login attempts is another effective way to protect your WordPress website from brute force attacks. Brute force attacks involve hackers attempting to gain access to your website by systematically trying different username and password combinations. By limiting the number of login attempts, you can significantly reduce the chances of a successful attack.

Tip: Most of WordPress security plugins such as Word fence or Solid Security (previous iThemes Security) allow you to limit login attempts  to your site.

Understanding the Common Vulnerabilities in WordPress

WordPress is one of the most popular content management systems (CMS) in the world. Near 40% of all website sites globally are using it. However, due to its popularity, it is also a common target for hackers. Understanding the common vulnerabilities in WordPress is crucial for website owners and administrators to protect their websites from being compromised. Here are some of the most common vulnerabilities found in WordPress:
1. Outdated WordPress Core: Failure to keep the WordPress core up-to-date is one of the most common vulnerabilities. Hackers are constantly looking for weaknesses in older versions of WordPress to exploit. Regularly updating the WordPress core helps to ensure that potential vulnerabilities are patched.
2. Weak Username and Password: Using weak usernames and passwords is another common vulnerability. Brute force attacks, where hackers attempt to guess your username and password, can be successful if you use easy-to-guess credentials. It is essential to use strong, unique usernames and passwords, as well 2FA mention earlier, to minimize the risk.
3. Insecure Themes and Plugins: Themes and plugins are excellent tools to add functionality and design to a WordPress website. However, using outdated or poorly-coded themes and plugins can introduce vulnerabilities. It is crucial to keep themes and plugins up-to-date and only use reputable sources.
4. File Inclusion Exploits: WordPress allows files to be included using functions like “include” and “require.” If these functions are not properly validated and sanitized, an attacker can use them to execute malicious code on the server. Proper input validation and sanitization should always be implemented to prevent file inclusion exploits.
5. Cross-Site Scripting (XSS): XSS vulnerabilities occur when an attacker is able to inject malicious code into a website, which is then executed by the victim’s browser. This can lead to various attacks, such as stealing sensitive information or defacing the website. Ensuring that all user input is properly sanitized and validated is critical to prevent XSS attacks.
6. SQL Injection: SQL injection occurs when an attacker is able to manipulate a website’s database queries by inserting malicious SQL code. This can lead to unauthorized access to the database or even complete control over the website. Using prepared statements or parametrised queries can help prevent SQL injection attacks.
7. Brute Force Attacks: Brute force attacks involve systematically attempting all possible combinations of usernames and passwords until the correct one is found. Implementing strong passwords, limiting login attempts, using two-factor authentication, adding CAPTCHA, and enforcing strong password policies, can help protect against brute force attacks.
8. Insufficient File Permissions: Incorrect file permissions can allow unauthorized users to modify or delete crucial files on a WordPress site. It is essential to set proper file permissions to prevent unauthorized access and modifications.

It is important to regularly update WordPress, themes, and plugins, use strong usernames and passwords, and employ security plugins and practices to protect against these common vulnerabilities. Regular monitoring and security audits can also help identify and address any potential vulnerabilities.

Recent Malware Security Cleaning and Prevention

A week ago we have been contacted by a client, who notice strange URL links in the source code of his website.

The website looks and acted normally without any issues or warnings. We analyzed the site and saw that just below the closing </html> tag in the source code were a bunch of over 30 hidden URLs.

The client had no idea how they got there. It was probably by an outdated plugin of the website, which has been compromised, and gave access to the hacker to gain control of the site and insert a code in a file in the root directory. This file “wp-blog-header.php” in which the string of code was inserted, was connecting to an outside URL and displaying all the hidden URLs on the bottom of the WordPress site.

We scan and compare the files of the WordPress and plugin installation, find and cleaned the vulnerable file, and removed the malware code. The site was back and operating normally again.

Once this was done, we had to take another step to protect the site, so that the hacker would not be able to come back and do it again.

We protected the site with the following steps:
1. Updating all plugins, theme, and WP core of the site
2. Changing all passwords for the site access
3. Hardening and configuring a premium security plugin
4. Adding 2FA to all users
5. Passing the site through CloudFlare WAF application firewall

The site is now protected and secured, but will be still work to monitor, maintain, and keep it regularly updated and secured.
