[geeks] SSH Scans Increasing

Has anyone else seen a very sharp increase in the number of SSH scans
since this weekend?

I have a program running out of cron that looks for break-ins and updates
my /etc/pf.conf automagically.  It mails me when it adds a new host to the
list.  I used to get 2 - 3 per week, but now I see 20 - 30 per day.

All the new scans appear to use the same dictionary.  It starts off with
some German words pertaining to academia, and then a straight alphabetical
dictionary attack (abel, abi, abraham, access, account...).  The IP
addresses scanning me don't come from the same country, so I suspect this
is some new botnet.
