These days, there's perhaps one more area even less secure and a better
route for attacking;

The wireless network. It's often fully exposed and unencrypted, even in
those environments that know better from the wired end. And, one can gain
in places totally free and annonymous wireless access into the internet
from which to probe and attack others from, but, this is an additional
side issue to the wirelss side attack on a company...
