A similar command on the log server on a class B network (/16) shows
1482 such attempts in the past 19 hours or so.  It's just a worm, and
unless you've got a weak password policy, you don't have anything to
worry about.  Eventually you just get used to it.  There's really not a
whole lot that can be done to prevent it.
