WordPress Pingback Attacks and our WAF
Mar 11, 2014Simon Moore
Summary
This post details the use of Cloudflare's Web Application Firewall (WAF) to block WordPress pingback attacks. It explains how attackers exploit the XML-RPC endpoint and the pingback mechanism to trigger HTTP requests to victim sites, effectively turning WordPress sites into attack vectors. The post highlights two specific WAF rules: WP0001 "WordPress Pingback Blocker" and rule 100000 "WordPress Numbers Botnet," which address the pingback abuse and the use of mutating query strings, respectively. It also mentions the existence of a WordPress-specific ruleset and the Cloudflare WordPress plugin.
