Emergency Steps: What to Do When Your WordPress Site Is Hacked
Symptoms Checklist
If you observe any of the following symptoms, your site or setup is affected by this issue:
- Account login credentials altered; administrator password reset not working
- Unwanted advertisements or spam banners appearing on your pages
- Unknown folders or PHP files appearing in your wp-content directory
- File manager logs showing files modified within the last 24 hours without your action
Why This Happens
WordPress sites get hacked when core files, themes, or plugins contain unpatched code vulnerabilities. Hackers exploit these holes to gain admin privileges, insert spam, or redirect visitors.
Common Underlying Causes
- Vulnerable Core/Plugins: Neglecting WordPress updates creates opportunities for hackers to run SQL injections.
- Nulled Themes: Installing pirated files that contain hidden malicious admin creators.
- Weak Login Portals: Brute-force attacks guessing simple administrator passwords.
DIY Quick Fix Steps
Here is what you can check or execute immediately to troubleshoot the issue:
- Change passwords immediately: Update hosting dashboard, FTP, and MySQL database passwords.
- Inspect wp-users database: Log into phpMyAdmin, check the wp_users table, and delete unauthorized admin rows.
- Replace core files: Re-download WordPress and overwrite wp-admin and wp-includes directories via FTP.
- Delete inactive plugins: Clean out files that might serve as backdoor hosts.
