OpenID phishing demo (via) A demonstration of the OpenID man-in-the-middle phishing attack. idproxy.net OpenIDs are immune to this particular variant due to the landing page not asking for your password (the phishing site could still provide their own redesigned landing page and hope users don’t notice though). # 28th May 2008, 8:09 am

PayPal Plans to Ban Unsafe Browsers. At first I thought they were going to encourage real anti-phishing features in browsers, which would be a big win for OpenID... but it turns out they’re just requiring EV SSL certificates which have been proven not to actually work. # 19th April 2008, 10:45 am

openid.yahoo.com. Yahoo!’s human readable guide to OpenID, complete with tour. It looks like they’re relying on the “sign-in seal” to protect against phishing. # 17th January 2008, 2:35 pm

MyOpenID adds Information Card Support. First client SSL certificates, now Information Cards. MyOpenID is certainly taking browser-based phishing solutions seriously. # 18th October 2007, 9:10 pm

Cronto. I saw a demo of this the other day—it’s a neat anti-phishing scheme that also protects against man in the middle attacks. It works using challenge/response: an image is shown which embeds a signed transaction code; the user then uses an application on their laptop or mobile phone to decode the image and enters the resulting code back in to the online application. # 2nd October 2007, 1:14 am

VeriSign’s SeatBelt OpenID plugin for Firefox. The first good example of browser integration for OpenID. It catches phishing attempts by watching out for rogue OpenID consumers that don’t redirect to the right place. # 17th August 2007, 5:37 pm
