What you see here is the attacker is trying guess both the username and password on the account. Here's a real "log file" from my server where it routinely records what happens each day.

The bad guy could try to just guess your password, attempting to log in again and again, hoping to get lucky. Not too hard to make a password they will never guess at 1/second rate.There is not time to make 100 billion guesses.1 guess/second = 31 million guesses per year.The attack fails mostly, but works some percentage of the time with an account with a weak password.Bad guys will try common passwords as guesses.Bad guys tries to log in again and again.as if they are trying all the words in a dictionary This is the "outside" case - bad guy is outside the site, guessing.The bad guy could try to guess your password to a site.
