    Curious. I wondered why I didn't see the little control character marker in
    there when I pulled this page up like I did with the front page. It's
    interesting, too, that someone should bother to put this sort of stuff in
    the form action section - but as a test I went and filled out the initial
    form with random info, just to see what the whole thing looked like.

    Figured that maybe they were putting the text in place to 'fill' your status
    bar so that you couldn't see the real stuff at the end of it. Seemed to be
    what happened. It seems like so much work to bother with the 0x01 exploit at
    the beginning of the whole thing, when you could have just as readily done
    all this with javascript onmouseover events so that unless you looked at the
    source, the button would have looked totally legit.

    Hmmm... where in there do you see %01? No, that is no 0x01 exploit, but
    just user:password@host quasi-RFC-compliant usage. The string is long so
    as to leave the user staring at the citibank+gibberish part, not to be
    made suspicious of the @IP part.
