Honestly, the safest thing to do is to NOT USE PASSWORD BASED LOGINS.
Amen.
I wrote a script to scan the Tor network for password-based login availability. If I have the time and no one beats me to it, it'll lead to a site that warns relay operators about security problems with their servers. For example, I can combine it with basic, non-invasive nmap results to warn about non-essential network applications, old OS versions, and old Tor versions as well.

Sebastian, how do you distinguish between the usual low level noise of ssh brute force bots out there from more invasive attacks?
Because this list is most likely just a bunch of internet background noise.
Honestly, the safest thing to do is to NOT USE PASSWORD BASED LOGINS. But what would be even better is to firewall ssh out so you can't get in except from specific ips and/or through say port knocking.

Dear list members,
My iptables dump, as promised (v4). Updated every hour and available as long as my relay is alive ;-)
I run a pretty tight ship, just one ssh user and harsh fail2ban settings. All these listed IP's are considered to be "the usual suspects".
Please feel free to use it, should give you a jump start. It is getting pretty quiet now since i passed the 300+ ip's milestone.
