So is it time to geo-restrict access?
If I had a good way to get that done, yes. That alone would have cut this down to 1 or 2 instead of a new one every time Thunderbird does a refresh.
Is there a list of IP addresses for different regions somewhere? I'm kinda busy playing whack a mole at the moment to go look myself

What firewall are you using?

iptables (still CentOS6 base.) Tho cPanel was included with it, so I have other management options... one guess which way I prefer to manage it

Looks like I need to install ipset on CentOS6, and I should be able to block by country then, yay!

Is there really much of a point geo blocking when it's usually hacked bots that are hammering on our servers?

And when geo-detection is so poor. Nearly everything that I do in Texas shows up as Ontario, Canada. Literally everything that I use identifies me as being in Canada.

The splintering of IPv4 space has definitely wreaked havoc on geo assessing.

In Soviet Russia, IP address blocks you!

That's fucked up - I always get Michigan!

We use ConfigServer Firewall/ CSF on all our servers (CentOS7 now, previously was on CentOS6)
Its a Stateful Packet Inspection (SPI) firewall, Login/Intrusion Detection and Security application for Linux servers. It is based on IP tables and very well block a decent level of attacks. Our CSF logs regularly blocks (first temporarily for some time and then if attack/invalid connection attempt continues then permenant block) and we get notified.
Few details from an email i received today!

Blocked: Permanent BlockCSF has also option to block the entire country, however they warn that using country-level filtering will negatively impact performance and you will notice slower response times on your websites. This is due to the sheer size of the CIDR range lists (the list for the U.S. is 621K in plain text and contains more than 37,000 entries) and the fact that the firewall must check each incoming IP address against the chosen list(s).
Another feature i really like is the option to perform a basic security, stability and settings. A sample screenshot of a server check. Green ones are ok the the pink ones to be fixed.

On the latest version it even has an option to send scheduled reports on this security check as new versions could have more checks.

Plus that joke wouldn't work if the attackers were in Alsace-Lorraine or Burkina Faso.

@Ambarishrh I saw that, doesn't really give me anything beyond what cPHulk is doing already. Might have to try it on some local systems tho.

I'd just K-Line the whole /16 subnet and be done with it and see if that slows it down.

I suspect that you may be unaware of the meaning that phrase has elsewhere lol
Wow. That's just sad. Guess I'll be expecting a visit from the FBI or NSA in a bit.
K-LINE is an old school IRC terminology. Was helping my old man with his IRC server today, lol.
K-LINE = block it forever... (on a Linux box, just use iptables, it's far, far easier).

That's what I've been doing with cphulk. The number of different systems being used is a little crazy. At this point I'm just wondering if I'll ever be able to prove anything, even tho I'm almost certain it's a government agency behind it.
Example of cPHulk email:
Block the IANA Netblock and call it done.
