Common Hacker Attacks on WordPress Sites
1. Brute Force Login
Automated attacks attempt to guess the administrator's username and password. It's essential to use strong passwords, limit login attempts, and enable two-factor authentication (2FA).
2. SQL Injection
Attackers inject malicious SQL commands into input fields to access or manipulate the database. Prevent this with proper input validation and secure plugins.
3. Malicious File Uploads
Hackers exploit vulnerable upload forms to inject PHP scripts that compromise the site. Limit allowed file types and block execution of uploaded scripts.
4. Cross-Site Scripting (XSS)
Allows the injection of malicious JavaScript into comments or forms. Executed code can steal user data or manipulate the site.
5. Cross-Site Request Forgery (CSRF)
Tricks logged-in users into performing unintended actions. Use CSRF tokens and server-side validation to protect your site.
6. Plugin or Theme Vulnerabilities
Outdated or poorly developed plugins/themes can open security holes. Always use updated and trusted components.
7. XML-RPC Abuse
The xmlrpc.php file can be exploited for brute force or DDoS attacks. Disable it if not needed.
8. Backdoors and Web Shells
Malicious code inserted into files to maintain persistent access even after malware removal. Monitor critical files regularly.
9. Malicious Redirects and SEO Spam
Manipulates files like .htaccess or wp-config.php to redirect visitors or inject spam links. Constant file integrity monitoring is essential.
10. DDoS (Denial of Service)
Attacks flood your site with traffic, making it unreachable. Use firewalls, CDN, and hosting-level protections to mitigate.
