The Waves We Saw, 2008 - 2014

We saw eight sequences of SSH attempts (complete list of articles in References), plus two for other services (POP3 and Wordpress).

The 2009-09-30 sequence was notable for trying only root, the 2012-04-01 sequence for being the first to attempt access to OpenBSD hosts.

We may have missed earlier sequences, early reports place the first similar attempts as far back as 2005 (Mobin and Paxson).
