Interesting Journal message resulting from intrusion attempt

I review my logs from time to time and there are always artifacts from intrusion attempts -- by the boat load; but I've never seen these two sshd messages before.  Anyone know what they are attempting?

Jul 01 07:21:35 odin sshd[17640]: error: connect_to d3alqb8vzo7fun.cloudfront.net: unknown host (No address associated with hostname)

and, several minutes later

Jul 01 07:49:57 odin sshd[21862]: error: kex_exchange_identification: Connection closed by remote host

In between those two, there were a couple brute force attempts on root, test and telly -- of course, all password logins are disallowed.

Re: Interesting Journal message resulting from intrusion attempt

The first sounds as if you have created an SSH (SOCKS?) proxy that will try to connect to any domain given to it. It so happens that this cloudfront address has no valid dns record.
