Spoofstick and phishing
You need Spoofstick. It installs to your browser and tells you what site you are really on, thus protecting you against sites pretending to be another site. It used to be, the browser address would always have the actual address, however browser addresses can be spoofed now.
Brian’s Buzz details this latest phishing attack, whereby a phishing site pretends to be a real site, and, say, asks for credit card and bank account numbers. This latest attack blocks the browser address bar with a graphic file that has a phoney address. It’s getting ugly out there folks.
Spoofstick can help here. It’s free, and works on Internet Explorer and, yes, Firefox!
