According to Gartner analyst Avivah Litan, this is happening because scammers are identifying higher-income targets, moving their phishing sites more frequently and switching up the types of business they try to impersonate.
Victims click on links they receive in the body of e-mails — and, increasingly, in instant messages — from sites purporting to be legitimate businesses like financial institutions, e-commerce and auction sites.
Approximately 109 million U.S. adults have received phishing e-mail attacks, up from 57 million in 2004, according to Gartner. Total loses from phishing attacks have risen to $2.8 billion in 2006, twice the amount lost in 2004.
According to the survey, conducted by Gartner analysts in August of this year, adults earning more than $100,000 per year are attacked more often than those making less.
According to Litan, cyber criminals have done a better job of identifying high-income individuals. They sell each other credit card numbers in online chat rooms, and can identify credit cards with higher spending limits by the first six digits on the card.
