In the last 2 months or so i've seen alot of these too, except i also get root 
attempts. on k-otiks site they have a brute forcing script for ssh that i 
think that a number of these scans are coming from even though it was only 
release on the 20th of last month. Here is the direct link

On examining /var/log/secure for several firewalls I manage remotely using
ssh I have observed a recurrent pattern of probing over the last several
that attempts to connect using user id's in the following order...

test / guest / admin / admin / user / test

I am seeing this, along with random usernames in large blocks from
compromised IPs

Is it worth reporting the behaviour to the net block assignees in case
they aren't aware their server might be compromised?

Usually not.  They are generally fools who won't reply, or if they do they
will blow you off.
