Yeah..

I didn't mind doing it, it was a lot of work but I learned a lot and was a bit of fun playing whack a mole :lol: Frustrating mostly due to the amount of time things take.. Like everything takes 100x longer than it should. I'm so far behind with everything it's unreal.

The logs end up so big that you can only spot the largest attacks first.. You deal with them, go back the next day and same again.. And again. And again..

It's why I used AI to write scripts to look though the logs for stuff which doesn't match predictable patterns. Like if there's millions of 404s from similar ip ranges then every IP range is checked to see how many other odd things are going on.. Long story short, I have a list of what was blocked and why plus what was flagged as suspect for me to decide manually.

What I mostly see is just a couple small number of ip addresses that only hit the server a couple times a day and just not worth bothering with. I'm blocking like 99℅ of all known attacks. If a attack isn't caught with the current rules then I get a list of suspect IP addresses to either do new rule or ignore them.

The server CPU is pretty much idle all the time now. Before it was maxing out a 4 core CPU trying to deal with all the traffic.

Only time the server may go down is during disk backups or kernel updates. It actually happens about once or twice a week.

I do keep an eye on things but people will have to let me know if the server is running slow constantly... It could mean something has got past my rules... But i haven't had to do any new rules for a while now. It's just a matter of "what's next" in the world of attacks..

Yeah, 12:51 SQL backup. The database will freeze for a few moments during backup :) The backup happens every 3 or 4 hours during the day.

I can actually see a "new problem".. These are not in time order, but IP order.. Basically loads beginning with 45.xxx.xxx.xxx , What they are doing is using 1 IP to hit a link once per day by the looks of it. They triggering 404, but only once. So they get around the firewall rules because they are rotating IPs all the time now :roll:

I can add a rule to block those easy enough. They not really bothering anything currently.. just making a mess of my logs :lol: :roll:

Looks like we was hit pretty hard recently as well, almost 68,000 IPs in the reporting queue now...

It really paints a picture on how things just get worse as time goes on.


Whats also somehow "worrying" is the IPs I am reporting a lot of the time are not even in the abuseipdb :shrug:

Something has happened literally just, because the abuse list I download is normally like 300 ips per 3 hours, its just jumped to 41,000 IPs. I only download the worst ones as well.

My own server has found over 70,000 IPs to block so far today (there are no duplicates either!) . Normally its more like around 2,000 -5,000 per day.

A lot of them seem to originate from Brazil, but we are being hammered from all over the world...

Incidentally I only report IPs once every two seconds.. I've just changed the script to report every second as there's over 70,000 IPs in the queue so far and its going up faster than they are getting reported !
