    desc: %(
      All versions of WordPress, as of March, 2018, are vulnerable to a
      denial of service attack by making large amounts of requests to the
      load-scripts.php file. This module allows users to configure a maximum
      number of requests (via `max_requests`), and the number of threads to
      use (`max_http_concurrency`) and will execute the requests and then
      check the status of the website.
