Server IP accessing hosted website and generating traffic

Hello,

I have little problem. My client has a website hosted which was working fine but suddenly it started to "eat" up all the bandwidth. From the logs I see that the server IP is trying to access certain files non-stop(screenshot attached). Last month I had the same problem with the other client.
Is it solely wordpress issue? Or it has something to do with cPanel? And how to stop this?

Thank you

Hello Infopro,

mod_userdir Protection is enabled for all users except DefaultHost (nobody).

The account have an actual domain. But it is an addon domain, if it matters.

I searched through web and haven't found any useful information so far

 

so, I tried to disable plugins(renaming folders) - nothing happened.
When I have created a requested file that was not in place then it started to request only it(there was a redirect when the file doesn't exist).
So now I have lowered the traffic but still 1000 requests per 3 minutes are hitting the file


Talked to Wordpress developer, he wasn't able to help me -_-
