The practice of using fraudulent e-mails and copies of legitimate websites to extract financial data from computer users for criminal purposes is called Phishing
Phishing is an e-mail fraud method in which the perpetrator sends out legitimate-looking email in an attempt to gather personal and financial information from recipients. The messages appear to come from well known and trustworthy Web sites. Web sites that are frequently spoofed by phishers include PayPal, eBay, MSN, Yahoo, BestBuy, and America Online and many Banking sites. Like the fishing expedition it’s named Phishing and it is a speculative venture: the phisher puts the lure hoping to fool at least a few of the prey that encounter the bait.
