Figure 1. PayPal (April 2004) spoof site (screenshots rescaled).

The phenomenon of Web spoofing, or creating hoax Web sites that closely mimic real sites in order to extract personal financial information from unwary Web visitors, is an increasingly popular form of online scam that contributes to identitybased credit and financial fraud and threatens to undermine consumer confidence in Internet shopping and banking [3].The FBI has referred to spoofing as “the hottest, and most troubling, new scam on the Internet ... contributing to a rise in identity theft, credit card fraud, and other Internet frauds” [2]. Approximately 30 such hoax attack sites are detected each day, even as many more go undetected [12]. Major U.S. businesses and government Web sites (such as BestBuy [5], eBay, PayPal [10], the InternalRevenue Service [8], and the Massachusetts State Lottery), as well as several banks (Citibank being the most frequently targeted [4]), report being victimized.

It was founded by Tumbleweed Communications along with a number of member banks, financial service institutions, and e-commerce providers.

It works with the FTC, the U.S. Department of Justice, and other federal, state, and local law enforcement agencies to design policies, enforcement methods, and penalties against online scams.
