It is probably looking for additional systems to compromise, and may
have reported itself back to some controlling system.

There is quite a lot of ssh password guessing going on over the
internet. If you have systems with the ssh port exposed, you can expect
to see a few hundred attempts a day in the logs - a slow enough rate
that you might not notice but the attackers are probably spreading their
attempts over thousands of systems. There are some packages that watch
the logs and firewall addresses with repeated failed attempts but none
are included in the distribution.
