While I applaud Bank of America for being the first to take serious steps to
combat phishing, SiteKey only elimintes one class of attack - the simple web
site that masquerades as the real site.
From what I can see in the article, SiteKey does not make use of digital
certificates to identify the user. Therefore it does nothing to eliminte
the class of more sophisticated man-in-the-middle attacks already in use
which make use of DNS poisoning to take users to the wrong site.
- For this case the browser will cough up the cookie to the phisher
site, which they can pass on to the BofA site. This will trigger the BofA
site to send back the image and phrase to the user via the Phisher site.
The user will enter the login and password; being none the wiser until it
fails or he is taken to the Phisher login action of choice.
Bottom line: The only way be reasonably sure you are at your bank's site
is to go to a secure login page and examine the certificate to be verify
it's issued by a reputable certificate issuer to your bank in your bank's
locality. If your bank uses a discount certificate issuer that you don't
recognize, don't trust them and get your bank to go with the real thing.
And better yet, bookmark the secure page to minimize chances of a typo
taking you to a secure type-alike site.
