The technique is called phishing, and some very clever crooks use it. Here's how it works. You put together a bunch of HTML-formatted e-mail messages asking people to reconfirm their account information. The messages look like the real McCoy, including corporate logos and from what at first glance looks like a legitimate e-mail address. The two scams that I got recently were from sites that had the eBay and Citibank logos. Both asked me to "verify my personal information" by clicking on a link in the message that took me to the phished site.
Many people have fallen for this scam - including retired police officers and others who have plenty of experience with the criminal mind. It is amazingly easy to pull off - all you need is a dollar and a dream and some good HTML coding skills to lift the appropriate logos from the true corporate sites. Buy a list of a few million e-mail addresses and you are ready to sit back and watch those passwords roll in, and soon you will have access to hundreds of IDs to harvest.
The Federal Trade Commission has issued a warning but until now it hasn't received much airplay. And several newspapers and Web sites have also covered the topic, including many in the U.K. where phishing seems to be picking up. In addition to the FTC page, here's an anti-phishing site has some useful information and links.
The term has actually been in use since the middle 1990s, but lately either the scam artists are getting better at their HTML coding skills or the intended marks are running better e-mail clients that support more HTML-formatted messages, or perhaps a little of both. According to e-mail protection vendor Brightmail, they are seeing plenty of phishing and brand spoofing scams, accounting for 27% of all e-mails filtered in October. The company, which also sells an anti-fraud screening service as part of its overall product lines in preventing spam and virus attacks, maintains a "decoy network" with over 2 million e-mail IDs to attract fraudulent emails. It doesn't help matters that people are very comfortable with ordering stuff over the Internet and sending their credit card numbers around cyberspace.
