Whether or not the cracker was given a shell account by the administrator or
s/he gained access through the back door, malevolent activity was taking
place on this box. It wasn't /attempted/ malevolent activity (like the
ongoing Nimda and CodeRed attacks which show up in your Apache logs - thank
you very much, Micro$oft - but don't actually do any harm), it was *real*
malevolent activity: downloading malware, then compiling it and running it.

You CANNOT TRUST the ~/.bash_history and logs on a machine on which this has
been taking place.
