According to research from VeriSign, the increase in the number of people transacting online -- up 13.2 per cent on last year -- means an increase in the number and variety of cybercrimes being committed -- with phishing the highest priority concern currently.
Phishing scams typically involve the receipt of an e-mail which attempts to solicit sensitive data -- such as bank account details. Often it will carry the branding of specific banks and ape very closely the appearance of a bank's Web site or own e-mail communications. For the unwary consumer spotting the minute differences can be tricky.
According to VeriSign, 93 percent of phishing e-mails that it studied were sent from forged or spoofed email addresses, which at first glance may appear to be genuine.
Just 5 percent of phishing e-mails came from sites making no attempt to disguise their destination, while 2 percent came from 'cousin' sites, which closely mimic the company site they are seeking to imitate but perhaps differ by a few characters. This suggests a general trend of phishers 'raising the bar'.
Paul Wood, chief information security analyst at MessageLabs, said the last six months has seen an increase in the sophistication of phishing e-mails but warned that a lack of awareness and end user education is also responsible for the continued success of even quite crude phishing attacks.
"As with viruses, people have been told time and time again not to open these e-mails and not to click on links and attachments but still they continue to do so," said Wood.
Such a lack of awareness means continued success for phishers and means they will most likely keep plying their trade for some time to come, according to Wood.
More likely to bring about the end of phishing e-mails is a move towards more covert forms of harvesting data -- such as spyware which requires even less end-user involvement.
Another problem in policing such crimes is the geographic spread of scammers and the need for careful cross border co-operation.
Although victims could be anywhere in the world it was crooks in China, Korea and the US who originated the most scams, according to VeriSign.
