Attack! Attack! Attack!…

<nerdy_post>

My home mail servers have been under a combined distributed denial-of-service (DDoS) attack and protocol hack attack yesterday and today.

 

The simultaneous attack has come from (but probably not orchestrated by) computer addresses in China, Taiwan, Brazil, USA, Australia, Israel, Holland, Sweden, Indonesia, Turkey, Canada, Uzbekistan, Mongolia, Hong Kong, India, Japan, Guatemala, Vietnam, Ethiopia, Peru, Bangladesh, Uganda, Benin, Moldova, Malaysia, Bosnia, Moldova, Turkey, Ukraine, South Korea, Romania, Cambodia, Tunisia, Kazakhstan and Cornwall!

 

So I've blocked internet connections from most of those countries and blocked the bad subnets of the rest.

 

I have quite good defence and firewall protection anyway but this attack has been quite sophisticated so it’s meant keep one step ahead of the bad guys. 

 

It’s worked (so far!). Yay! 🥳
