I don't believe that there is an obvious distinction between "malicious" 
cracking and "harmless" cracking. If someone has compromised your system
and altered files, you are really not in any position to assume anything
about that person's intentions (or competence; they may have caused damage
accidentally).

        [Kunz, Peter]  That's probably a major issue: evenif it's just a
script kiddie that just foudn a hole, not knowing the system, s/he could
wreak havoc without intention or even knowing it.

Even if the intention was only to deface a web page, you probably don't
know whether or not the first thing the cracker did was to install a back
door. Detecting such modifications (assuming you have cryptographic
checksums of your original binaries available...) or reinstalling your
system is likely to require a lot of time/money. 

        [Kunz, Peter]  Not if you've set up your logging/detection properly
:-)
