Recently I have been getting a website traffic spike from all over the world. And it has been as frequent as 1 min per web request.
Since I realized this problem, I have created a firewall to block all the access except traffic locally.
I have scanned for malware in my server, and remove unnecessary files from my website. But the traffic is not slowing.
Most of the request is trying to visit some weird path:
Which does not exist on my website.
This surge of traffic actually causes my server CPU to increased to a ridiculous level. Any suggestion on how I can stop this? Is this possibly an attack?
Is there anything I can do?
