Part 1 — Cloudflare: Setup & Exact WAF / Firewall Rules (WordPress/WooCommerce)

Why Cloudflare first?

Cloudflare blocks the majority of automated attacks, hides your origin IP (if configured), offers WAF ruleset tuned for WordPress, and supports rate limiting and challenges. Use it as the first line of defense.

Quick setup checklist

1. Create Cloudflare account and add your domain.
2. Change DNS to Cloudflare’s nameservers.
3. Enable “Full (strict)” SSL between Cloudflare and origin.
4. Turn on WAF (Web Application Firewall) — the Managed WordPress ruleset if available.
5. Enable Bot Management / Bot Fight Mode (if available on your plan).
6. Configure Rate Limiting for login/admin endpoints.

Exact, copy-paste Cloudflare Firewall Rules (recommended)

Note: Cloudflare UI changed over time; these are logical expressions you can enter into Cloudflare Firewall Rules. Adjust IPs / trusted lists to your needs.

A. Admin protection (block/Managed Challenge)

• Name: Block admin abuse
• Expression:
• Action: Managed Challenge (or Block for very strict sites)

(http.host eq "yourdomain.com" and (http.request.uri.path contains "/wp-login.php" or http.request.uri.path starts_with "/wp-admin")) and not ip.src in { <your-office-ip> , <your-ci-ip> }

B. Rate limit login attempts

• Use Cloudflare Rate Limiting:
  • URL: yourdomain.com/wp-login.php
  • Threshold: 10 requests per 60 seconds (tune to your traffic)
  • Action: Challenge (CAPTCHA) or Block for repeated offenders.

C. Block known bad user agents & common exploit paths

• Name: Block suspicious UA & payloads
• Expression example:
• Action: Block

(http.user_agent contains "sqlmap" or http.user_agent contains "acunetix" or http.user_agent contains "nikto")

D. Block requests with suspicious query strings (common spam payloads)

• Name: Block suspicious querystrings
• Expression:
• Action: Challenge or Block

http.request.uri.query contains "base64_" or http.request.uri.query contains "eval(" or http.request.uri.query contains "cmd="

E. Block direct access to xmlrpc.php (if you do not use it)

• Expression: (http.request.uri.path eq “/xmlrpc.php”)
• Action: Block (or Managed Challenge). Note: If you use xmlrpc for legitimate services, restrict by allowed IPs.

F. Managed ruleset

• Enable Cloudflare’s Managed Ruleset for WordPress and WooCommerce if available — these include OWASP core rules and WordPress specific protections.

Notes on origin IP and hiding

• Ensure your origin IP is not publicly known (remove it from DNS history where possible, or put server behind Cloudflare and restrict origin to accept traffic only from Cloudflare IP ranges). This prevents attackers from bypassing Cloudflare.

Part 2 — Server-Wise Setup (cPanel / VPS / Cloud) — Hardening Steps

Goal: If attackers obtain server access or credentials, they can’t execute uploaded files or alter site code easily.

A. cPanel hosting (shared / managed)

• Use secure control panel credentials and 2FA if cPanel supports it.
• Restrict Origin access: If using Cloudflare, allow only Cloudflare IPs in the hosting firewall (cPanel IP Blocker / .htaccess rules).

Place .htaccess in /public_html/wp-content/uploads/ with:

<FilesMatch "\.php$">
  Order Deny,Allow
  Deny from all
</FilesMatch>

For modern Apache (Require directive):

<FilesMatch "\.php$">
  Require all denied
</FilesMatch>

• Protect wp-config.php: Set file permission to 400 or 440 and, if needed, add .htaccess rule to block direct access.
• Disable xmlrpc.php if unused: via .htaccess block or plugin.
• Set correct file permissions: directories 755, files 644, special wp-config.php → 400/440.

B. VPS (Ubuntu / Debian / CentOS)

• System user hygiene
  • Create a non-root user with sudo. Don’t use root for day-to-day.
• Firewall
  • UFW (Ubuntu): allow only SSH (port 22 or custom), HTTP (80), HTTPS (443), restrict SSH to your office IPs if possible.
• Fail2ban — protect SSH and limit repeated login attempts.
• Harden PHP & FPM
  • Disable dangerous functions in php.ini: disable_functions = exec,passthru,shell_exec,system,proc_open,popen
  • Run PHP-FPM pools as separate users per site (if hosting multiple sites).

Uploads PHP execution block

Create /.user.ini or nginx config to deny .php execution in /wp-content/uploads. For nginx:

location ~* /wp-content/uploads/.*\.php$ {
  deny all;
}

For Apache, use .htaccess as above.

• File permissions & ownership
  • Chown files to the site user, not www-data (or match server’s recommended approach), and set 644/755 (files/dirs).
• Backups
  • Use offsite automated backups (S3, Backblaze, or provider’s snapshot). Keep daily incremental + weekly full for 30+ days.

Cloud provider (AWS / GCP / DigitalOcean)

• VPC & Security Groups — restrict access to only required ports and to trusted IPs for admin.
• Use IAM best practices (min privilege for admin users).
• Use managed DB services to isolate DB from public network; allow access only from application/subnet.
• Automated snapshots and immutable backups.
• Use CDN / WAF (Cloudflare, AWS WAF) in front of origin and block origin by IP.

Part 3 — WordPress Config & File Hardening (must do)

Disable plugin/theme file edits & modifications

Add to wp-config.php:

define('DISALLOW_FILE_EDIT', true);
define('DISALLOW_FILE_MODS', true);

This prevents plugin/theme editor in WP admin and disallows installing/updating from admin (useful on production).

Force secure file permissions

• Files: 644 (or 640)
• Directories: 755 (or 750)
• wp-config.php: 440 or 400 (protects from other users).

Block PHP execution in uploads (repeat — it’s critical)

.htaccess in /wp-content/uploads/:

<FilesMatch "\.(php|php5|phps|phtml)$">
  Require all denied
</FilesMatch>

(Or deny from all syntax for older Apache.)

Disable XML-RPC if unused

• Block via .htaccess or Cloudflare or plugin. Example .htaccess:

<Files xmlrpc.php>
  Require all denied
</Files>

XML-RPC is a frequent brute force vector.

Change DB user privileges (limit to necessary)

From MySQL shell, create user that only has these:

GRANT SELECT, INSERT, UPDATE, DELETE ON database_name.* TO 'wp_user'@'localhost' IDENTIFIED BY 'strong_password';
FLUSH PRIVILEGES;

Avoid giving DROP, ALTER, GRANT unless required. This reduces damage if DB credentials are leaked.

Part 4 — Monitoring, Malware Detection & Backups

Monitoring essentials

• File integrity monitoring (Wordfence, MalCare, or host-level scanning).
• Login monitoring and 2FA for all admin users.
• Automated daily scans for malware and changed files.

Backups

• Daily incremental + weekly full kept offsite for 30 days.
• Test restores monthly. Backups are your fastest path to recovery.

 

Part 5 — SEO Spam Cleanup SOP (Step-by-Step)

When SEO spam happens, speed and discipline matter. Below is a step-by-step SOP you can follow.

Phase 0 — Immediate containment (first 30–60 minutes)

• Enable “Under Attack Mode” in Cloudflare to present JS challenge to visitors.
• Put site in maintenance mode (serve a simple static page) so crawlers don’t index junk content while you work.
• Take a full backup (files + DB) — label as pre-clean-YYYYMMDD. Do not overwrite existing clean backups.

Phase 1 — Detection & triage

• Scan files: use malware scanner (Wordfence / Sucuri / host scanner) to locate new/modified files.
• Check recent file changes (timestamps) and new files in /wp-content/uploads/, /wp-content/plugins/, /wp-content/themes/.
• Look for .php files in uploads (spam payload often hides as images or uploader scripts). If found, quarantine them (move to a safe folder offsite).
• Search DB for injected content (common columns):
  • wp_posts.post_content for spammy links/iframes
  • wp_options for malicious auto_loaders
  • wp_users for suspicious admin accounts

Useful SQL pattern searches:

SELECT ID, post_title FROM wp_posts WHERE post_content LIKE '%viagra%' OR post_content LIKE '%casino%' LIMIT 50;
SELECT option_name, option_value FROM wp_options WHERE option_value LIKE '%<iframe%' OR option_value LIKE '%base64_%';

Phase 2 — Removal

• Remove malicious files discovered in scans (delete from server after backup).
• Clean DB rows: remove injected spam posts or reset option values to safe versions. If there are many injected posts, mark them post_status = ‘trash’ or delete after backup.
• Reset compromised admin accounts and remove any unknown users. Create new admin user with a strong password and 2FA.
• Check for persistence: hackers often add backdoors — look for eval(base64_decode( or unfamiliar PHP files in theme/plugin folders.

Phase 3 — Lockdown

• Rotate all credentials: WP admin passwords, DB password, FTP/SFTP, cPanel.
• Change API keys used by plugins (e.g., payment gateways) if compromised.
• Reapply uploads PHP execution block and ensure DISALLOW_FILE_MODS is set.

Phase 4 — Post-cleanup & Verify

• Scan again (multiple scanners) and confirm no malicious files remain.
• Restore clean backups if needed (if too difficult to clean manually).
• Check Google Search Console for affected URLs — note any new indexed spam pages. Use GSC Removals to temporarily remove harmful URLs.
• Submit sitemap again after cleanup and request indexing for cleaned pages (optional).

Phase 5 — Notification & Prevention

• Notify stakeholders (site owners, payment provider if PII compromised).
• Implement additional prevention: enforce 2FA, strict firewall rules, host-level hardening, and scheduled scans.
• Document the incident: root cause, steps taken, and follow-up actions.

Part 6 — Recovery Examples (practical commands & snippets)

A. Deny PHP execution in uploads (Apache .htaccess):

# /wp-content/uploads/.htaccess
<IfModule mod_rewrite.c>
RewriteEngine On
</IfModule>

# Deny access to PHP files
<FilesMatch "\.php$">
  Require all denied
</FilesMatch>

B. wp-config.php hardening (add near top)

// Disable file editing and modifications from WP Admin
define('DISALLOW_FILE_EDIT', true);
define('DISALLOW_FILE_MODS', true);

// Force HTTPS (if site uses HTTPS)
if (isset($_SERVER['HTTP_X_FORWARDED_PROTO']) && $_SERVER['HTTP_X_FORWARDED_PROTO'] == 'https') {
  $_SERVER['HTTPS'] = 'on';
}

C. MySQL create user with minimal privileges

CREATE USER 'wp_user'@'localhost' IDENTIFIED BY 'S0m3$tr0ngP@ss';
GRANT SELECT, INSERT, UPDATE, DELETE ON `your_db_name`.* TO 'wp_user'@'localhost';
FLUSH PRIVILEGES;

Part 7 — Long-Term Preventive Checklist (daily/weekly/monthly)

Daily

• Check security plugin scan reports
• Verify backups completed successfully

Weekly

• Check recent file changes and new users
• Review Cloudflare WAF logs for blocked attempts

Monthly

• Test backup restore (important!)
• Review server & plugin updates; apply security updates in staging first

Quarterly

• Full penetration test or professional security audit

Part 8 — SEO Considerations After an Attack

• If spam content was indexed, create clean content and re-submit sitemaps.
• Use 410 Gone for hard-deleted spam pages (preferred over 404 for clarity).
• Use GSC Removals for immediate temporary hiding of URLs while you clean.
• Monitor search results for any lingering spam keywords and request reindexing after cleanup.

Appendix — Common Signals of Compromise (what to look for)

• Sudden flood of new pages with spammy keywords (casino, viagra, loan, casino)
• Unknown admin users added
• Modified core files (wp-load.php, index.php) or unfamiliar PHP files in plugin/theme folders
• New scheduled tasks / cron jobs that you didn’t add
• Outgoing requests from server to unknown domains (check netstat / logs)

Final Checklist

To enhance WordPress security, configure Cloudflare with WAF, Bot Management, and Rate Limiting for /wp-login.php while blocking /xmlrpc.php if unused; define DISALLOW_FILE_EDIT and DISALLOW_FILE_MODS in wp-config.php, block PHP execution in /wp-content/uploads/, and set file permissions to 644 for files and 755 for directories, with wp-config.php at 400/440. Restrict the database user to SELECT, INSERT, UPDATE, and DELETE permissions only, implement daily malware scans, maintain offsite backups, enforce 2FA, and change all passwords following any compromise, following a standard operating procedure (SOP) of: taking a backup, conducting a thorough scan, removing threats, rotating credentials, submitting removals in Google Search Console, and re-submitting the sitemap.
