Phishing is the name given to e-mails that claim to be from a bank but which are actually sent by fraudsters.
Although online banking fraud losses decreased by a third from £33.5m in 2006 to £22.6m in 2007, the fraudsters are still having some success in duping customers with phishing e-mails, said Apacs.
Sandra Quinn, director of communications at Apacs, said, "Although online banking fraud losses fell last year, the fraudsters clearly are not giving up. Phishing scams are continuing to rise and they are becoming ever more sophisticated, which is why we want to remind people to remain wise to them."
She said, "The advice is quite simple: just remember that your bank will never send you e-mails asking you to disclose Pin numbers, log-in details or complete passwords - if you receive an e-mail of this nature you should delete it."
Apacs research shows that although the number of people either deleting or taking no action when receiving a phishing email has increased from 75% in 2006 to 82% last year, there are still nearly one in five people who don't follow these common sense precautions.
Phishing emails can be reported to Apacs.
