1. Introduction — Why WordPress Sites are Targets

WordPress powers over 45% of all websites worldwide. Its popularity makes it a prime target for hackers, botnets, and malicious actors. DDoS attacks can:

• Overload your server

• Crash your site

• Impact user experience

• Negatively affect SEO

2. What is a DDoS Attack and How WordPress DDoS Protection Helps

A DDoS attack occurs when multiple compromised systems (bots) flood a website with traffic, overwhelming the server’s resources.

Example:
Imagine a small coffee shop receiving 10,000 orders per minute — legitimate customers cannot get served, staff is overwhelmed, and operations fail. That’s exactly what a DDoS attack does to a website.

Types of DDoS attacks:

1. Volumetric – Overwhelms bandwidth (UDP floods, ICMP floods).

2. Protocol – Exploits server resources (SYN flood, Ping of Death).

3. Application Layer – Overloads specific applications like WordPress login pages.

3. Signs Your WordPress Site Needs DDoS Protection

Check for:

• Sudden slowdown or site unresponsiveness

• Spike in 5xx errors (502, 503)

• Abnormal CPU/memory/network usage

• Traffic anomalies in analytics

• Repeated access to /wp-login.php or /xmlrpc.php

---

4. How to Detect a DDoS Attack on WordPress

1. Check Uptime Monitoring Alerts — UptimeRobot, Pingdom

2. Analyze Server Logs — Identify high-frequency IPs

• awk '{print $1}' /var/log/nginx/access.log | sort | uniq -c | sort -nr | head

1. Look for Suspicious Patterns — Repeated requests, non-existent pages, or unusual user agents

2. Compare Analytics vs Logs — If GA shows fewer users than logs, traffic is likely fake

3. Check Host/CDN Dashboards — Many managed hosts highlight abnormal spikes

5. Emergency Steps to Stop a DDoS Attack on WordPress

• Enable Cloudflare Under Attack Mode

• Use DNS-level WAF (Cloudflare, Sucuri, Imperva)

• Block malicious IPs and countries

• Apply rate limiting for /wp-login.php and /xmlrpc.php

• Temporarily disable vulnerable endpoints

• Contact hosting provider for emergency support

10. FAQs

Q1: Can a plugin alone protect my WordPress site from DDoS?
A: No, large DDoS attacks require network-level protection like Cloudflare or Sucuri.

Q2: How do I differentiate between DDoS and genuine traffic spikes?
A: Check session duration, bounce rate, and IP patterns in logs vs analytics.

Q3: Will free Cloudflare handle all attacks?
A: Free plan protects against small/medium attacks. Large attacks may require Pro/Business plans.

Q4: Should I block countries during an attack?
A: Temporarily yes, if your audience is localized.

Q5: Can DDoS attacks harm SEO?
A: Yes, downtime and slow site speed negatively affect Google rankings.
