Why does the site start using all the resources of the server?

Question

Drupal

The site on mirahub for the second time (22.05, the first time on 21.04.) is unavailable for more than a day. Gives a 504 error. The support team says that there has been a sharp jump in the use of all resources. What could be the reason?

Answer 1

Change all access to the server, look for suspicious scripts
