xmlrpc.php

Security Researcher Detected: You might have ended up here because your site vulnerability scanner found something interesting. Hi! I'm a security engineer and I'm having a good time interacting with the people and bots that are interested in information security.

You will hopefully find this site is well-secured and I'm not interested in being hacked. I'm interested in learning about how people try to hack me, though.

What is this endpoint?

xmlrpc.php

WordPress XML-RPC endpoint, frequently abused for brute-force amplification and pingback DDoS

What an attacker could do

This endpoint enables `system.multicall` password brute-force amplification (hundreds of login attempts per request) and pingback-based reflective DDoS and SSRF against third parties.

How to defend it

Disable XML-RPC entirely if unused (via plugin or `add_filter('xmlrpc_enabled','__return_false')`), or block the file at the web-server level and disable the pingback method.
