Phishing is a way for hacker to gain credentials or personal information by using a website that appears to be legitimate.
NSS Labs, an independent security research group has done a research to find out which internet browser is best on thwarting phishing attempts. They tested on Microsoft Windows Internet Explorer 8, Mozilla Firefox 3, Apple Safari 4, Google Chrome 2, and Opera 10 Beta. The result of their study shows that Internet Explorer 8 was the best browser tested at thwarting phishing attempts.
