An anonymous reader writes "Stanford University and Microsoft Research have published a study that claims that the new Extended Validation SSL Certificates in IE7 are ineffective (PDF). The study, based on user testing, found that EV certificates don't improve users' ability to detect attacks, that the interface can be spoofed, and that training users actually decreases their ability to detect attacks. The study will be presented at Usable Security 2007 next month, which is a little late now that the new certificates are already being issued."
