The 'ADMROCKS' is a known bind hack.  Upgrade your bind packages
_immediately_ after a restore, otherwise the hacker will be able to get back
into your system quite easily for as long as you run that particular version
of bind.  It happened to me four times in one day ((hack => restore => hack)
x4) on a test server running the vulnerable bind packages.

Sounds like the person exploited bind to gain root access, then infected you
with a few other things.  Also, check for strange lines in /etc/services
towards the end.  With the bind exploit, they usually kill off bind, fubar
the bind service, and open a root hole via an ip:port combo that does not
require a pw to log into your server.

Very nasty indeed.
