Publishing four posts and their images in quick succession over WordPress’s
\nXML-RPC interface tripped the host’s protections. The site stopped answering
\nrequests entirely — and so did cPanel — until whatever had been
\ntriggered let go on its own.<\/p>\n
This is the interesting part, because the symptoms were weird<\/em>.<\/p>\n Ports open and nothing responding is a specific signature. A crashed service refuses The posting pattern looked like an attack, because mechanically it was XML-RPC is the most brute-forced endpoint in all of WordPress. It accepts What I sent it: repeated authenticated calls, several file uploads, multiple post Worth writing down because it cost time. Early on I checked whether ports were open, That was wrong.<\/strong> An open port is not a working service. When I actually sent Check that the thing responds<\/em>. Not that it is listening.<\/p>\n All of the above is mitigation. It makes a robot act politely.
