- DDoS attacks aim to overwhelm your server resources with fake traffic.
- WordPress is vulnerable because every request triggers PHP execution.
- XML-RPC is a common vector for amplification attacks.
- True DDoS protection must happen at the network edge, not on the server.
What Is a DDoS Attack?
A Distributed Denial of Service (DDoS) attack floods your server with so much traffic that it can't serve legitimate visitors. Attacks can range from simple volumetric floods to sophisticated application-layer attacks that mimic real user behaviour.
WordPress sites are particularly vulnerable because each page request triggers PHP execution and database queries. Even a moderate DDoS attack can overwhelm a WordPress server that handles legitimate traffic just fine.
Why WordPress Is a Target
WordPress powers over 40% of all websites, making it the most popular target for automated attacks. Attackers know the default URLs (wp-login.php, xmlrpc.php, wp-admin), the common plugin vulnerabilities, and the typical server configurations.
The XML-RPC interface is a particularly common attack vector. It allows multiple WordPress API calls in a single HTTP request, amplifying the impact of each malicious request.
Network-Level DDoS Mitigation
Effective DDoS protection must operate at the network level, not within WordPress. By the time a DDoS request reaches PHP, the damage is already done—server resources are consumed regardless of whether WordPress processes the request.
G7Cloud's network absorbs DDoS traffic at the edge, filtering malicious requests before they reach your server. Volumetric attacks are mitigated through traffic scrubbing, while application-layer attacks are caught by the WordPress-tuned WAF.
Building a DDoS-Resilient WordPress Site
Beyond network-level protection, there are steps you can take to improve your WordPress site's resilience: disable XML-RPC if you don't need it, limit login attempts, use strong passwords, and keep WordPress and plugins updated.
But the most important step is choosing a hosting platform with built-in DDoS protection. No amount of WordPress-level hardening can compensate for a hosting environment that crumbles under attack.
