Phishing scams are increasing by 50 percent from month to month, according to the Anti-Phishing Working Group, an industry association of banks and Internet companies that monitors the trend. The consortium's research indicated that an average of about 50 new phishing attacks were spawned every day in June 2004, with a host of prominent company names being used.
And although phishing scams may sound easy to detect, 28 percent of U.S. adults were unable to distinguish between phishing attacks and genuine online forms, according to a national survey commissioned by MailFrontier, a computer security firm based in Palo Alto, Calif.
Observers say this is understandable among customers adapting to online banking.
"It's hard when consumers get legitimate e-mails and then get phony ones," said Hillebrand.
And some worry about senior citizens' susceptibility to phishing.
"These consumers are new to the Internet," Dave Jevan, chairman of the Anti-Phishing Working Group, testified during a March Senate hearing, and "not educated about the new dangers of phishing fraud."
Still, consumers' groups and government agencies, including the Federal Trade Commission and Federal Bureau of Investigation, offer a number of suggestions for avoiding phishing and other scams:
Similarly, said Jevan, "There is no reason for any site to request your ATM PIN. Any site that requests this is fraudulent."
Even apart from such phishing tricks, however, ATM fraud itself remains a serious concern for law enforcement officials. The American Bankers Association has estimated that more than $50 million a year is stolen via schemes involving doctored ATMs.
