If they do it right, it's not a giveaway.  If they're quick, thorough,
and accurate, they can certainly do it right.  On the other hand, I've
seen cracked Solaris boxes on which the rootkit installed a patched
version of GNU's ls in place of the default ls.  That was a pretty
obvious giveaway.

The thing with rootkits is that they're pretty target-specific.  They're
not usually robust enough to be installed on a different Linux
distribution or even a different version of the intended target distro.
Rootkits aren't what I usually worry about; It's the determined,
knowledgeable attackers that I don't like.  Fortunately there aren't as
many of them to worry about.

noah
