The problem with thinking like that though is you aren't taking the
consumer into account. Say my mom or dad want to pay their visa bill
and they are unsure where to go on the internet to pay. They do a
google search and sure enough,  the find a page that has a link to
visas payment portal or account login page. Now they are happy because
even though they are not as technically advanced as people on this
list, and they did eventually get to the visa site on their own. They
checked the URL and made sure that it was the visa site that they were
at. But regardless of what they did to protect themselves, they still
become the victims of identity theft. How much more is the average
consumer who uses the computer a max of 2 hours a week expected to
know? You surely don't expect them to start learning about frames
sources or automatic redirects in their web browser, do you?

If a script from site A can replace the contents of a frame
within a document from site B then site A is able to violate
the *integrity* of B's contents. This is unacceptable.

A script from site A can only replace the contents of a window object
within a frame from site B if site B is specifically opened through
scripting from site A. Site A cannot interact with any window object
that it has not created itself, it has to open a new window, wait for it
to load and then load a new document in the frame inside this new
window. It doesn't even know if you already have an existing browser
window pointing at WindowsUpdate or your banking site because it didn't
open those windows.

You have to look at the prerequisite attack scenario. You are surfing to
some random site and out of nowhere it opens WellsFargo.com or
WindowsUpdate. At this point you are thinking one of 2 things, either

"What the.. I didn't go to WindowsUpdate/WellsFargo .. Let me just close
that window .. Damn popups"

or

"Hey how nice, WindowsUpdate/WellsFargo magically appeared in front of
me and I didn't even intend to go there .. I was just surfing for porn
.. Let me hurridly download some stuff from there and give it my account
details"
