Another exploit is for someone to get a certificate for
MacysCalif.com and publish a website resembling the real Macy's
website. Everything looks OK to the user, the little padlock is locked,
and all traffic is encrypted. Except it isn't going to the real Macy's,
but to the fraudulent one. Who likely will pass it along to the
real Macy's, harvesting the userid/password. Or simply redirecting
and getting out of the middle, after harvesting user credentials.
