How to Hack a WordPress Website: A Step-by-Step Guide Using Penetration Testing Tools

WordPress, a widely popular CMS platform, powers approximately 43.4% of all websites on the internet. Among websites using a known Content Management System (CMS), WordPress dominates with 62.8%. Big brands like Microsoft rely on this robust CMS for their websites. However, its widespread use also makes WordPress a frequent target for hackers.

In this article, we will explore a demonstration of ethical hacking on a WordPress website. This guide uses penetration testing tools to uncover vulnerabilities. Please note this is for educational purposes only—unauthorized hacking is illegal.

What Is a CMS?

A CMS (Content Management System) is software that enables users to create, manage, and publish digital content. Platforms like WordPress allow even non-coders to design and manage websites efficiently.

Penetration Testing on a WordPress Website

Let’s dive into an ethical hacking demonstration to assess the security of a WordPress site. The process involves various tools and techniques.

1. Checking the Server’s Availability

Start by verifying if the target server is live:

• Open the terminal and execute a ping command to check connectivity with the server’s IP address.
• If the server responds, it’s ready for further analysis.

2. Scanning for Open Ports

Perform a port scan using Nmap:

• Command: sudo nmap -A [IP Address]
• This aggressive scan identifies open ports, running services, and versions.

For example:

• Port 22 (SSH): OpenSSH 7.6p1 (possibly vulnerable versions).
• Port 80 (HTTP): Apache HTTPD 2.4.24 web server.
• Ports 139 and 445: SMB and Samba services.

3. Analyzing the Website’s Backend Technology

Use tools like Wappalyzer to identify backend technologies:

• WordPress version: 5.0
• Programming language: PHP
• Database: MySQL

Knowing the WordPress version helps locate vulnerabilities.

4. Using WPScan for Vulnerability Assessment

WPScan is a powerful tool for discovering WordPress vulnerabilities.

• Command: wpscan --url [Target URL] --api-token [Your API Token]

This scan reveals:

• Plugin vulnerabilities
• Active users
• Directory listings
• XML-RPC status

In one scan, WPScan discovered 70 vulnerabilities, including outdated themes and plugins.

5. Exploiting Vulnerabilities

Hackers often exploit outdated WordPress versions or plugins. For instance:

• Search for exploits specific to the WordPress version using terms like “WordPress 5.0 exploit.”
• Tools like Metasploit can execute Remote Code Execution (RCE) attacks if vulnerabilities are present.

Example:

An exploit targeting WordPress 5.0 required an authenticated user with author privileges. With the correct username and password, the attacker gained access to the WordPress dashboard.

Brute Force Attacks on WordPress

If no immediate exploit is found, brute-forcing the login page is another approach:

• Command: wpscan --url [Target URL] --password-attack xmlrpc --usernames [Usernames] --wordlist [Path to Wordlist]
• This attempts multiple password combinations to gain access.

Gaining Shell Access via Reverse Shell

Once access to the WordPress dashboard is achieved, hackers can inject malicious PHP code:

1. Navigate to Appearance > Editor in the dashboard.
2. Modify the 404.php file with a reverse shell script.
3. Configure a listener on your machine to capture the connection.

Protecting Your WordPress Site

1. Keep WordPress Updated: Regular updates address vulnerabilities in themes, plugins, and the core system.
2. Use Strong Passwords: Protect your admin account with complex, unique passwords.
3. Limit Login Attempts: Restrict the number of failed login attempts to prevent brute-force attacks.
4. Install Security Plugins: Use plugins like Wordfence to monitor and protect your site.
5. Disable XML-RPC: This reduces the risk of brute-force and other attacks.

FAQs

1. What tools are used for ethical hacking on WordPress?
Tools like WPScan, Nmap, and Metasploit are commonly used for penetration testing and vulnerability assessment.

2. Is hacking WordPress websites illegal?
Yes, hacking without explicit permission is illegal and punishable under cybercrime laws.

3. How can I secure my WordPress site?
Update all components regularly, use strong passwords, install security plugins, and limit login attempts.

Conclusion

WordPress security should never be underestimated. Ethical hackers and developers must identify and patch vulnerabilities to safeguard their websites. Follow best practices and always keep your WordPress installation up-to-date to minimize the risk of attacks.

This article highlights the importance of securing your WordPress site while offering insights into the tools and techniques used in ethical hacking. Stay vigilant and prioritize your website’s security.
