According to a Gartner report quoted in this article in CIO Asia magazine, Phisher schemes are reducing the number of purchases made online. However, reading the quoted data from the report, it doesn't sound like that's necessarily a bad thing.
Author Lorraine Cosgrove Ware writes:
"Nevertheless, 75 percent of the 5,000 online consumers who Gartner surveyed in May said they have become more cautious about where they shop online, and one-third reported buying fewer items than they would typically purchase due to security concerns. Eighty percent of those surveyed said they now trust commercial e-mail less, while 85 percent claimed to delete unexpected e-mails without ever opening them."
I think Ware's analysis is off. This sounds like great progress to me. People looking to shop online are getting smarter about which sites and emails they trust. I don't see anything in the data she quoted showing a correlation between the savvier shoppers and a decline in legitimate e-commerce revenue. Am I missing something?
