Distributed Botnet - Sextortion

[Hugo Almeida]

Hello, Good afternoon, I recently received a distributed botnet attack on my Proxmox Mail Gateway antispam server, called sextortion, I wonder if there is a way to stop this type of attack on Proxmox Mail Gateway.

Thanks in advance for your attention.

Sincerely,

Hugo Almeida

hi,

I wonder if there is a way to stop this type of attack on Proxmox Mail Gateway.

stopping ddos attacks on PMG is no different than stopping ddos attacks on another linux server.

generally, firewalls and ddos protection services (akamai, cloudflare, etc.) are helpful.

for simple rule-based rate-limiting you could install and set up fail2ban on your server too.
