Jennifer, I made a reply to someone disagreeing with your statement on
copying the drive, supporting your contention.  However, most courts will
not accept log files on magnetic media as evidence due to the ease of
alteration.  This is why we collect all logs on a central syslog server that
writes directly to write-once media.  That is irrefutable evidence.

Also, don't forget to document everything!  You have no idea if this
box was used for truly illicit purposes, instead of just trying to
break into other machines.

If the hacker was using your box to distribute child porn, mp3s, or
warez then you will look like the guilty party.

Just to be on the safe side, make sure you keep a record of everything
you do just to cover yourself.  It sounds too late to make a copy of
the hard drive, and I don't know if this means contacting the FBI, but
they won't care unless $5000 worth of damage is done.  But at the very
least write everything you can down in a journal so that if the police
ever do come knocking on your door because child porn or something was
distributed, then at least you have something as documentation.

If this happens again, I would probably make a copy of the hard drive,
or at the very least the log files since they can be entered as
evidence of a hacked box.
