hypnosec writes "A student at the University of Oslo, Norway has claimed that Phishing attacks can be carried out through the use of URI and users of Firefox and Opera are vulnerable to such attacks. Malicious web pages can be stored into data URIs (Uniform Resource Identifiers) whereby an entire webpage's code can be stuffed into a string, which if clicked on will instruct the browser to unpack the payload and present it to the user in form of a page. This is where the whole thing gets a bit dangerous. In his paper, Phishing by data URI [PDF], Henning Klevjer has claimed that through his method he was able to successfully load the pages on Firefox and Opera. The method however failed on Google Chrome and Internet Explorer."
