Under attack!
« on: May 28, 2025, 11:47:38 AM »
This morning I got a warning about CPU usage on our server... log in to find over 3500 "guests" browsing our forum!

It's not just here either - the other forum hosted on this server was also being battered.

No harm done, it seems; but the sheer number of IP addresses involved is unreal. Mostly from Vietnam, Malaysia, Brazil and a few from China possibly.

I've been adding rules to the firewall to drop the traffic from the busiest suspect IP ranges, but there are so many of them, that I might be catching real users in the fallout. If I do (and you won't see this message unfortunately!) then I apologise. I've got my thinking hat on as to how I can do something a bit more targeted & temporary - a bit like fail2ban but specific to our forum.
Cheers,
Ade

Thanks Ade,

The last couple of weeks we have been having lots of applications from Spammers for membership. For the ones from Russian I have resorted to blocking the 'span' of their local IP addresses  :)

Further to the attack from the Far East (mostly)... I've been testing a new firewall package... but it looks like it's being a bit too aggressive & blocking everyone!

Apologies if you were unable to access the forum earlier. I've now disabled it pending further efforts.
Cheers,
Ade
