“Browse freely but carry a SpoofStick” is the slogan for Corestreet’s free browser extension that helps users detect spoofed (fake) websites.
The heart of most “phishing” schemes, spoofed websites are usually made to look like well known, branded sites, such as citibank.com. The phony URLs often closely resemble the real thing. Phishing for the “accidental tourist,” attackers hope to lure people to a spoofed site where they will enter their credit card numbers and other personal information.
SpoofStick makes it easier to spot a spoofed website by prominently displaying the most relevant domain information. Note the actual domain name displayed below the address line in this screen capture.
SpoofStick is available for both IE and Firefox.
