[root@borg log]#

My server is somewhat isolated, in the sense that theres no actual website or anything super public. Its behind a router and I do have a couple forwarded ports such as ssh. But looks like someone decided to try a brute force attack on it. This log goes on and on and on.....

But root is an invalid user. In fact, every single user is invalid, exept for one. To be safe, time to check if there's a patch for sshd in case the attacker decides to try something more advanced.

I will also contact the ISP that owns that IP range.
