Firewall rules to block Cloud Providers

This packet contains a zip file with IP subnets from Cloud providers, to be blocked on the Firewall.
Those are IP subnets from which attackers attempted abuse against our systems since January 2021.

For instance, if an IP from a Cloud provider attacked one of our sites, we looked at the subnet for that IP, verified that was from a Cloud provider (normally renting VPC), and added to the list.

This package contains 247 rules, blocking a total of 55,608,576 IP Addresses from Cloud Providers like: Amazon AWS, Azure, Google Cloud, Digital Ocean, OVH... from which servers arrive attacks and attempts of exploit.

It contains the list of subnets, in plain text, and a Shell script for Ubuntu, to add the rules to ufw (Ubuntu's easy to use firewall)

It also contains another list of around 1,200 rules, blocking individual IP Addresses and subnets, from which we received attacks. It block 815,336 IP Addresses.

You can apply the rules directly to your Ubuntu Server using the script provided.
Or you can import them to a Firewall Software using the CSV file.
Or you can use them with our plugin PHP WordPress Firewall or module PHP Drupal Firewall.

If you block IP Addresses (or Subnets, which comprise many IP Addresses) the requests from those IP don't get to your server, so you save a lot of CPU, Memory and bandwidth.
