One in 20 people fall for phishing scams and provide their account information to bogus versions of PayPal, EBay and other ecommerce sites, according to a study by Rachna Dhamija of the Harvard Center for Research on Computation and Society.
The study presented real online banking and fake phishing sites to subjects to see if they could tell the two types apart. ... The most sophisticated site caught out 90 percent of the 22 people participating.
I began using the Netcraft Toolbar in October, which works on Internet Explorer and Mozilla Firefox and detects known phishing sites and other suspicious pages. I've tried some of the phish links to see how well the toolbar works, and it has warned me about all of them.
