Why hammer the home page?

Question

Information Security

Wordpress site
I found this thing on my site: they hammer 6000 requests into the main page today,
185.6.8.3 Internet Explorer Windows 5.1
At the same time, the installed wp cerber (spam blocker) does not work, I had to manually blacklist the ip, what is it?

Answer 1

Learn to protect the site not with plugins, but by properly setting up the environment (triggers for network activity).
(and you won't have any more questions like this)

Answer 2

This is a bot.
