Re: Hotmail & Passport (.NET Accounts) Vulnerability

And youâ?Tll get an email on attacker () attacker com'

Sure you didnt mean to replace one of the email addesses in there with
'attacker () attacker com'?
Even if you do, it doesn't seem to work. I tried switching each one for my
own and no such luck. I only recieved an email when both the addresses were
set to my hotmail account.
That means it's only any good if you have access to the users hotmail
account but don't know their password in the first place.
