Thanks Amir.

One challenge we face is that users are so programmed to entering username
and password on a login page, that as soon as they see something that looks
like a login page, they start typing and hit the enter. And while the page
is being submitted to the server, they look at anything else (URL, chrome).
I have had a few of my friends phished this way who did realize (that they
were phished) just at the same time they hit enter. So anything in a chrome
will almost fails to stop the attack in a simple web form that is used very
often. So it was very important to us to have the indicator as close to the
login field as possible. I think the chrome indicators may be more useful
when credit card and other information is being requested as more users will
try to be a bit more careful.

I'm sure everyone will agree that personalized indicators (your own selected
picture) catch your attention much better than something you may have to

So far the feedback from our users have been really positive.

Yahoo'snew tool

Naveen: I wish to congratulate you on the Yahoo! tool. It is a simple, 
useful indicator.

Our experiments show a significant advantage to user-customized 
indicators like yours, and they are also more robust to fake internal 
window (PIP) attacks. BTW, in our experiment, we clarified to users the 
distinction between the content area and the chrome area (in terms of 
trust), and still had very high (37%) spoof rate using `classical` 
browser indicators. So I don't think user's lack of sufficient attention 
to the chrome areas is due (only) to lack of understanding. Better 
indicators can help a lot (although I think we can and should do even 
more than indicators).

We are now working on a much larger experiment and may include 
Yahoo-like indicator. Anybody interested in cooperating in the 
experiment, please contact me.

We present our existing experiment results in:

    *Security and Identification Indicators for Browsers against
    Spoofing and Phishing Attacks* 
    /Amir Herzberg and Ahmad Gbara/
available at http://eprint.iacr.org/2004/155.

I also recently posted another article, reviewing the basic problems and 
some solutions, including some details of the registry solutions I'm 
advocating (certificate registry and content registry):
*Browsers Defenses Against Phishing, Spoofing and Malware*, available at 

Comments welcome.

Best, Amir*
