This comes from the AbuseIPDB with a confidence level of 95%. I use
the following command to download and sort the IPs:
$ curl -G https://api.abuseipdb.com/api/v2/blacklist -d confidenceMinimum=95 -H "Key: $ABUSEIPDB_API_KEY" -H "Accept: text/plain" | sort > /tmp/ips.txt
I manually remove the IPv6 addresses and save them to a different
filr, then I add the XML formatting to files and run them through
tidy.

I updated the list with a few dozen more hosts that we brute forcing
SSH but failed to even negotiate a connection because they are using
old ciphers. I will still block them because they attempted 100+ co-
nnections.
This uses the ipsets feature of the Linux kernel to create lists of
IPs (though could be MACs, IP:port, etc) that we can block via the
existing firewalld zone we are already using. In my testing it works
on CentOS 7, Ubuntu 16.04, and Ubuntu 18.04.
The list of abusive IPs currently comes from HPC's systemd journal,
where I filtered for hosts that had attempted and failed to log in
over 100 times. The list is formatted with tidy, for example:
$ tidy -xml -iq -m -w 0 roles/common/files/abusers-ipv4.xml
See: https://firewalld.org/2015/12/ipset-support
- Don't run the static files as templates
- Use a separate playbook for related tasks
- Use a template for security.sources.list
