It is late a night and I just had a thought I want to share: have you ever went to a website, say, your abnk, where when you try to login -- pasting the username and password so there is no possibility of a typo -- it does not work and sends you to a "login failed, try again" page, it then works there?
I do not know about you, but if I were going to try to steal credentials, creating a website that sits in front of the real one (think man in the middle attack) would come into mind.
That is all I have for now: just food for though.
