"New Universal Man-in-the-Middle Phishing Kit" ?

http://www.rsasecurity.com/press_release.asp?doc_id=7667

....snip...
How it works

Using the Universal Man-in-the-Middle Phishing Kit, the fraudster creates a fraudulent URL via a simple and
user-friendly online interface. This URL communicates with the legitimate website of the targeted organization in
real-time - whether it is the online banking site of a financial institution, the order tunnel of an ecommerce company,
or any other such business transacting with its users online. The victim receives a "standard" phishing email, and when
clicking on the link s/he is directed to the fraudulent URL. The victim then interacts with genuine content from the
legitimate website - which has been "imported" by the attack into the phishing URL - thus allowing the fraudster
seamless, invisible and immediate access to the victim's personal information.

how does an URL communicate with anything?
and why wouldn't my browser complain about an invalid certificate for my banks site?

any ideas?

They mean "the server accessed via the URL".

You're not going to your bank's site, your going to the phisher's site
because you clicked on the fraudulent URL he sent you. The phisher has
a valid certificate for his own site, of course, so there's nothing for
your browser to complain about (it has no way of knowing where you
*think* you're going).

ok,
but then I will see the bogus URL
as in:

http://www.mybank.com.onlineid3979954057.rwrth.ws/customer.h tm

in my browser, right?

True, but that's not the "man in the middle" type of attack that the
original article was asking about.

Maybe. But that's true of traditional phishing sites, it's nothing new
in this case. The MitM attack simply adds the ability of the site to
display things on the page that supposedly only the real site can
display (such as your last ATM transaction).
