How Hackers Target WordPress Sites (And How to Stop Them)
How Hackers Target WordPress Sites and How to Stop Them: Essential Security Methods and Best Practices
Common Attack Methods
- Brute Force Attacks: This method involves automated attempts to guess passwords until the correct one is found. It can lead to unauthorized access if strong passwords are not used.
- Malware Infections: Hackers can inject malicious code into your site, which can steal data or redirect users to harmful sites. Regular scans are essential to detect such threats.
- SQL Injection: This attack targets the database by inserting malicious SQL queries through input fields, allowing hackers to manipulate or steal data.
- Cross-Site Scripting (XSS): In this attack, hackers inject malicious scripts into web pages viewed by users, potentially compromising their data and accounts.
WordPress Brute-Force Attacks: Methods & Malware Spread
WordPress, with more than 18M websites world wide, is the most prominent WCMS. Is because of its popularity that this and other well-known WCMSs have been systematically attacked for the past years by different threat actors seeking disposable infrastructure for their attacks.Brute-force attacks are one of the most common types of attacks against WCMSs. The goal of such an attack is to guess a valid user name and password in order to access the WCMS administration panel. Attackers especially take advantage of users choosing weak credentials. Successfully brute-forced websites are typically used for hosting C&Cs, scams, and drive-by attacks to spread malware.

WordPress Application-Layer Attacks: SQLi, XSS & AWS Security
There are two main risks that containerised WordPress on AWS has; vulnerable container images and application-layer attacks. Such implementation is organised as the layered defence, which incorporates continuous scanning of the Amazon ECR/Inspector images with additional AWS WAF and EventBridge/Lambda automation. SQLinjection (SQLi) and cross-site-scripting (XSS) tests resulted in 100% blocking of SQLi payloads, and 90.95 percent mitigation of XSS with its managed and internal WordPress-specific rules (/wp-login.php, xmlrpc.php).

Essential Security Methods
- Use Strong Passwords: Ensure that all user accounts, especially admin accounts, use complex passwords that are difficult to guess.
- Regular Updates: Keep WordPress core, themes, and plugins updated to patch vulnerabilities that hackers may exploit.
- Install Security Plugins: Utilize security plugins that offer features like firewalls, malware scanning, and login attempt monitoring to bolster your site's defenses.
- Limit Login Attempts: Restrict the number of login attempts to prevent brute force attacks from succeeding.
- Enable Two-Factor Authentication: Adding an extra layer of security through two-factor authentication can significantly reduce the risk of unauthorized access.
Best Practices for Prevention
- Regular Backups: Schedule regular backups of your website to ensure you can restore it quickly in case of an attack.
- Routine Security Checks: Conduct regular security audits to identify and address potential vulnerabilities before they can be exploited.
- Proactive Monitoring: Implement monitoring tools that alert you to suspicious activities or unauthorized changes on your site.
- Educate Users: Train users on security best practices, including recognizing phishing attempts and using secure passwords.
- Monitor Access Logs: Regularly review access logs to identify any unusual activity that may indicate a security breach.
Recovery Steps if Hacked
- Change All Passwords: Immediately change passwords for all user accounts, especially admin accounts, to prevent further unauthorized access.
- Contact Professionals: Reach out to security experts who can help assess the damage and clean your site of any malware or vulnerabilities.
- Scan and Remove Malware: Use security tools to scan your site for malware and remove any malicious code found.
