How To Remove Malware From Hacked WordPress Site

That sinking feeling. You visit your website, and something’s wrong. Maybe it’s redirecting to a spammy site, showing weird content, or maybe Google is flashing a big red warning. Finding out your WordPress site has been hacked is stressful, frustrating, and downright scary. Your hard work, your business, your online presence – it all feels suddenly vulnerable.

Lately hackers have become very intelligent that, you won’t even know your website is hacked. Your website will work perfectly normal unless you search in google about your website and find chinese or russian language pages indexed from your website.

We once had a customer where his website was hacked, he came to know about it only after his hosting blocked him from sending any emails. The reason was the hacker didn’t do anything to his website other than using his server to send thousands of spam emails every day. So type of website attack can vary, but these issues can be sorted out.

Take a deep breath. While it’s serious, it’s almost always fixable. Acting quickly and methodically is key.

This comprehensive guide will walk you through everything you need to know:

Whether you’re tackling this yourself or deciding if you need professional help, this guide is for you. Dealing with hacked websites is something we handle regularly at Upniche, and we understand the urgency and precision required. Let’s get your site back online and secure.

Part 1: Are You Sure It’s Malware? Identifying the Hack

Before diving into cleanup, let’s confirm you’re dealing with a malware infection. Hackers are sneaky, and the signs aren’t always obvious. Look out for:

1. Strange Redirects: Your site automatically sends visitors (or just you) to spammy, malicious, or irrelevant websites.
2. Unexpected Content/Pop-ups: Ads, links, text, or pop-ups appear that you didn’t add. Often pharmaceutical ads, gambling sites, or explicit content.
3. Can’t Log In / New Admin Users: Your password suddenly doesn’t work, or you find new, unfamiliar administrator accounts in your WordPress Users section.
4. Google/Browser Warnings: Visitors (or you) see warnings like “This site may be hacked,” “Deceptive site ahead,” or similar messages from Google Safe Browse or antivirus programs.
5. Hosting Account Suspension: Your hosting provider might suspend your account if they detect malware or malicious activity originating from your site.
6. Sudden Performance Drop: Your site becomes incredibly slow or unresponsive. While not always malware, it’s a common symptom.
7. Emails Sent From Your Account Fail / Marked as Spam: Hackers often use compromised sites to send spam emails, damaging your server’s reputation.
8. Suspicious Files or Code: You notice unfamiliar files or folders in your WordPress installation (via FTP/File Manager) or strange code snippets within your existing files.
9. Scheduled Tasks Acting Up: Unusual cron jobs appearing in your hosting panel.
10. Security Plugin Alerts: If you have a security plugin, it might be screaming warnings at you.

Verification Tools:

• Google Safe Browse: Check your site’s status here: https://transparencyreport.google.com/safe-Browse/search
• Sucuri SiteCheck: A popular free scanner: https://sitecheck.sucuri.net/
• VirusTotal: Can scan your URL against multiple antivirus engines: https://www.virustotal.com/
• Check Server Logs: Access logs and error logs (usually via cPanel or your hosting dashboard) can show suspicious IP activity, errors related to malicious scripts, or POST requests trying to exploit vulnerabilities.

If you see several of these signs, it’s time to move to damage control.

Part 2: Immediate First Steps – Damage Control

Okay, you’ve likely confirmed a hack. Don’t panic, but act fast.

1. Stay Calm: Panic leads to mistakes. You can fix this.
2. Put Your Site in Maintenance Mode: Use a plugin (if you can access admin) or manually create a .maintenance file in your WordPress root directory. This prevents visitors from seeing the hacked site or potentially getting infected themselves. Alternatively, contact your host; they might have tools to temporarily take the site offline safely.
3. Backup Your Current Infected Site: This sounds counter-intuitive, right? Why back up a broken site? This backup is not for restoring later. It’s for analysis. You might need to examine the hacked files or database later to understand the attack vector or ensure you’ve removed everything. Label it clearly (e.g., “INFECTED_BACKUP_APRIL_5_2025”). Store it offline, separate from your clean backups.
4. Change ALL Critical Passwords Immediately: Assume your credentials might be compromised. Change passwords for:
   • All WordPress admin accounts
   • Hosting account control panel (cPanel, Plesk, etc.)
   • Database user(s)
   • FTP/SFTP accounts
   • Any other services connected to your website (e.g., payment gateways if integrated directly).
   • Use strong, unique passwords for each service (a password manager is highly recommended).

Part 3: The Cleanup Process – Step-by-Step Guide

This is where the real work begins. It requires patience and attention to detail. Missing even one malicious file can lead to reinfection.

A Quick Word on Expertise: Manually cleaning a hacked WordPress site can be complex, technical, and time-consuming. If you’re not comfortable working with code, files via FTP/SFTP, or databases, or if you’re short on time and need your site back ASAP, consider professional help. Upniche’s dedicated WordPress Malware Removal Service involves experts who do this daily, ensuring a thorough clean and helping secure your site against future attacks.

If you’re ready to proceed manually, here’s the process:

Step 1: Gather Your Tools

• FTP/SFTP Client: Like FileZilla (free) or Cyberduck (free). You’ll need your FTP/SFTP credentials from your host.
• Text Editor: A plain text editor capable of showing code (like VS Code, Sublime Text, Notepad++ – not Microsoft Word).
• Hosting Control Panel Access: cPanel, Plesk, or your host’s custom panel.
• Fresh Copies: Download the latest version of WordPress core, plus clean copies of your theme(s) and plugins from trusted sources (WordPress.org or the original vendor).
• Your Clean Backups: Hopefully, you have recent, known-good backups from before the infection. These are invaluable.

Step 2: Scan Your Local Computer

Ensure the device you’re working from isn’t compromised. Run a thorough scan with reputable antivirus/anti-malware software.

Step 3: Check and Replace WordPress Core Files

Hackers often modify core WordPress files (wp-admin and wp-includes directories).

• Connect to your site via FTP/SFTP.
• Carefully delete the wp-admin and wp-includes directories on your server. Do NOT delete wp-content or wp-config.php yet.
• Unzip the fresh WordPress download on your local computer.
• Upload the new, clean wp-admin and wp-includes directories from the fresh download to your server via FTP/SFTP.
• Examine loose files in the root directory (like index.php, wp-load.php, etc.). Compare them against the fresh WordPress download. Replace any that look suspicious or have different modification dates/sizes than expected. Be extremely careful NOT to delete or overwrite your wp-config.php file at this stage.

Pro Tip: If you have SSH access, using WP-CLI command wp core verify-checksums can quickly identify modified core files.

Step 4: Inspect Your wp-config.php File

This file contains your database connection details and security keys. It’s a prime target.

• Download wp-config.php from your server root via FTP/SFTP.
• Open it in your text editor.
• Look carefully for any strange code injections, unusual characters, or long strings of text that seem out of place, especially at the very beginning or end of the file.
• Compare it with the wp-config-sample.php file from the fresh WordPress download to understand the standard structure.
• If you find malicious code, carefully remove it. If you’re unsure, consider regenerating your WordPress security keys/salts (you can use the official generator: https://api.wordpress.org/secret-key/1.1/salt/) and replacing the old ones in the file. Double-check that your database credentials (DB_NAME, DB_USER, DB_PASSWORD, DB_HOST) are correct.
• Upload the cleaned wp-config.php file back to the server, overwriting the potentially compromised one.

Step 5: Clean the wp-content Directory

This is often where malware hides, especially in themes and plugins.

• Plugins:
  • Navigate to the /wp-content/plugins/ directory via FTP/SFTP.
  • Delete ALL plugin folders. Yes, all of them. It’s the safest way to ensure no hidden backdoors remain. Make a note of the plugins you were using. You will reinstall fresh copies later.
• Themes:
  • Navigate to /wp-content/themes/.
  • Delete all theme folders EXCEPT the one you are actively using AND a default theme (e.g., twentytwentyfour).
  • Download a fresh copy of your active theme from the original source (vendor or WordPress.org). Delete the potentially compromised version on your server and upload the fresh copy.
  • Carefully inspect the files of the default theme or replace it with a fresh copy from a new WordPress download as well. Hackers sometimes hide code even in inactive themes.
• Uploads Directory (/wp-content/uploads/):
  • This is challenging as it contains your legitimate media files. Hackers often hide PHP backdoors or malicious scripts here disguised as images.
  • Carefully inspect this folder via FTP/SFTP. Look for any files that aren’t images/videos/documents (e.g., .php, .js, .py, .sh files). Sort by modification date to spot recently added suspicious files.
  • Delete any suspicious files found. Be very careful not to delete legitimate uploads. If unsure, download questionable files and scan them locally or use an online scanner.
  • Advanced: Search within files in the uploads directory for common malicious PHP functions like eval, base64_decode, gzinflate, passthru, shell_exec.
• Check for Other Suspicious Files/Folders: Look for any files or folders directly within wp-content that don’t belong (e.g., tmp, cache folders with executable files, PHP files pretending to be .ico files).

Step 6: Clean the WordPress Database

Malware can also hide in your database – injecting spam links, creating fake users, or redirecting scripts.

• Backup Your Database FIRST: Before making any changes, create a backup of your current database using tools like phpMyAdmin (usually accessible via your hosting control panel). Label this backup clearly (e.g., “INFECTED_DB_BACKUP_APRIL_5_2025”).
• Access phpMyAdmin: Log in and select your WordPress database.
• Check the wp_users Table: Look for any user accounts with administrator privileges that you don’t recognize. Delete them immediately. Check other user profiles for suspicious URLs in the website field.
• Inspect Posts and Pages (wp_posts table): Scan through your post content for spammy links, keywords, or hidden <iframe> or <script> tags. You might need to use SQL queries to search for common malware patterns (e.g., searching for <script>, base64_decode). Be cautious with automated replacements; review changes carefully.
• Check Comments (wp_comments table): Look for spam comments containing links or scripts.
• Check the wp_options Table: This table contains site settings. Pay close attention to the siteurl and home options. Ensure they point to the correct domain and aren’t redirecting elsewhere. Look for other suspicious options possibly added by malware.
• Use a Scanner Plugin (Temporarily): After cleaning files, you might temporarily install a security plugin like Wordfence or Sucuri Scanner. Their database scanning features can sometimes help identify injected malware you missed manually. Remember to remove the plugin afterward if you don’t intend to keep it, or configure it properly (see Part 4).

Step 7: Check Server Configuration Files (.htaccess, user.ini)

Hackers often modify the .htaccess file (in your WordPress root directory) to perform malicious redirects or block access.

• Download your current .htaccess file via FTP/SFTP.
• Open it in a text editor. Look for rules you didn’t add, especially complex RewriteRule entries pointing to external domains or PHP files.
• If you’re unsure, it’s often safest to delete the existing .htaccess file and replace it with the default WordPress version:

Code snippet

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress

• Note: If you had custom rules (e.g., for security or redirects), you’ll need to add them back carefully later. After saving the default .htaccess, go to your WordPress Admin > Settings > Permalinks and simply click “Save Changes” to regenerate the rules correctly.
• Also check for and inspect any php.ini or user.ini files in your root or core directories, as these can sometimes be used to execute malicious code.

Step 8: Reinstall Your Themes and Plugins

Now that the core system is likely clean, reinstall only necessary themes and plugins from trusted sources.

• Log in to your WordPress admin dashboard.
• Go to Appearance > Themes and activate your cleaned theme (or a default one).
• Go to Plugins > Add New. Search for and install fresh copies of the essential plugins you previously noted down. ONLY install plugins from the official WordPress repository or reputable premium plugin vendors. Never install “nulled” or cracked premium plugins/themes – they are a primary source of malware.
• Delete any plugins or themes you no longer need.

Step 9: Final Scan

Install one or two reputable security plugins (e.g., Wordfence, Sucuri Scanner, MalCare) and run a full site scan. They might catch remnants you missed. Address any issues they find.

Part 4: Post-Cleanup Actions – Securing Your Site for the Future

Cleaning is only half the battle. You need to lock down your site to prevent this from happening again.

1. Change Passwords AGAIN: Yes, one more time for good measure, especially your WordPress admin and database passwords.
2. Update EVERYTHING: Ensure WordPress core, all themes, and all plugins are running their latest versions. Outdated software is the #1 way hackers get in. Enable auto-updates where feasible.
3. Implement Security Best Practices (Crucial!):
   • Strong Passwords & User Roles: Enforce strong passwords for all users. Don’t give users higher roles (like Administrator) than they need.
   • Install & Configure a Security Plugin: Choose a reputable plugin (Wordfence, Sucuri Security, iThemes Security, MalCare) and configure it properly. Enable the firewall (WAF), limit login attempts, set up regular scans, and enable critical alerts.
   • Enable Two-Factor Authentication (2FA): Adds a vital layer of security to your login process.
   • Disable File Editing: Add define('DISALLOW_FILE_EDIT', true); to your wp-config.php file to prevent code editing from the WordPress dashboard.
   • Change Default ‘admin’ Username: If you’re still using ‘admin’, create a new administrator account with a unique username and delete the old one.
   • Regular Backups: Implement an automated backup schedule (daily or even more frequently for active sites). Store backups offsite (e.g., Dropbox, Google Drive, Amazon S3) and test restoring them periodically.
   • Use Latest PHP Version: Ensure your hosting runs a supported and up-to-date version of PHP.
   • File Permissions: Ensure directory permissions are typically 755 and file permissions are 644, except for wp-config.php which can be 440 or 400 for extra security (consult your host if unsure).
   • Consider a Cloud-Based WAF: Services like Cloudflare or Sucuri WAF can block malicious traffic before it even reaches your server.
4. Request Blacklist Removal:
   • Use the tools mentioned earlier (Google Safe Browse, Sucuri SiteCheck, etc.) to see if your site is blacklisted.
   • If listed, submit review requests through Google Search Console (under Security Issues) and other relevant authorities once you are certain the site is clean. This can take time.
5. Inform Your Host: Let your hosting provider know you’ve cleaned the site, especially if they suspended it. They might perform their own checks.
6. Monitor Closely: Keep a close eye on your site for any returning signs of trouble. Check security plugin logs and server logs periodically. Consider uptime monitoring services.

Part 5: When DIY Isn’t Enough – Calling the Professionals

Let’s be honest: the manual cleanup process is intensive. It requires technical comfort, time, and a keen eye for detail. If you’ve tried and failed, if you’re overwhelmed, or if you simply need guaranteed results quickly to protect your business, professional help is often the wisest investment.
