SSH root attacks on the rise

This is not directly Oracle related, but probably still of interest.

SSH Password Brute Forcing may be on the Rise

Out of curiosity I pulled the ssh login attempts from /var/log/messages an internet facing server, and the data  corresponds to what was shown in the article.

What was interesting was that all ssh attempts that I saw were for root.  In the past when I have looked at these there are a number of different accounts being attacked, but now the attacks are all for root.
