If you presently have a Drupal installation, you need to update it urgently.
A botnet is currently exploiting a Drupal CMS vulnerability, by using already compromised systems to infect new machines. The botnet is exploiting the CVE-2018-7600 vulnerability, known as Drupalgeddon 2, to gain the ability to execute commands on a server running Drupal.
If you are running 7.x, upgrade to Drupal 7.58 https://www.drupal.org/docs/7/update
If you are running 8.5.x, upgrade to Drupal 8.5.1. https://www.drupal.org/docs/8/update

Update 27/04/18
Today (27/04/18) we’ve updated our mod security rules to try to help mitigate these attacks. This does not remove the requirement to update your Drupal store. There is a small chance that the updates may cause some false positives – please contact our support team if you have any issues.
