Stopping the cross-site authentication attack



A new form of phishing attack deposits an HTML tag on the vulnerable service to trap users into authenticating.

Phishing messages should be a familiar sight to most readers. They appear to come from your bank or eBay and ask you to enter your credentials on a spoofed login page. A phishing attack uses trickery to spy on user credentials. Another method, known as cross-site scripting (XSS, as CSS stands for Cascading Style Sheets), places active code on a vulnerable page. The unsuspecting user’s web browser runs the code and sends the user’s login data to the attacker.
