Hi Jason,
Maybe I've mis-understood, but from the information given I'm not sure if that
constitutes a man in the middle attack. What's probably happening is that the
browser is re-sending the session cookie to the server and since the session
hasn't timed-out yet the site gets reloaded within the other tab.
A man in the middle would mean that some how someone malicious is stealing your
cookie whilst its being transmitted from your PC to the server. If you bank is
using SSL and there is a proxy in between - then your browser should complain
or give you a warning asking if you'd like to proceed...
I guess if you are concerned that its loading sites from other tabs - then its
more likely a feature bug rather than an inherent security problem in itself?
Cheers

Subject: IE7 add-on
Hi.
I have just loaded the ie7 add-on 'open-last-tab', has anyone else had a play
with this? From initial results i have found this to be a great
'man-in-the-middle' attack tool.
Example on Bank site(no-names):
Log into your bank, open another tab within the window i.e. google. Close the
banking tab, hit Alt-X and the 'logged-in' banking window re-opens. I have also
attempted this on other applications and the majority work. Can someone advise
if M$ have provided us with a great MITM plug-in tool?
