Phishing flaw a danger to alternative browsers is interesting, to say the least. Internationalized domain names were introduced so we could have URLs in all languages – not just English. The modern browsers, especially gecko-based ones, like Netscape and Firefox support IDN already. Users of these browsers could be fooled into beleiving that www.pÃ ypal.com is www.paypal.com, for example. It’s called a “homograph attack”.
The articles says :
Microsoft has not implemented support for IDN yet, so its IE browser is not vulnerable to the flaw.
Microsoft hasn’t implemented support for many standards, so that’s no surprise, really.
