Hey! I’m under a slow speed botnet attack to my email server. The problem I’m seeing is that the IP addresses are never used twice. So, fail2ban won’t really help. Any other suggestions as to how to block this attack?
Are you sure you’re never seeing the same address twice? As you can see from my posts I was lucky because the bot net was trying to break into an email server using IDs that aren’t actually valid for the server so I was basically able to put the invalid user check in to basically dump it after one attempt.
