Crooks are set to exploit the start of a £2.5billion online shopping spree to launch a new cyber crime wave.
Experts say criminals are poised to take advantage of a flood of unsuspecting bargain hunters surfing the net in the post Christmas sales, which begin in earnest tomorrow.
It comes amid reports that online crooks are turning to holding householders to ransom to get steal money.
The Boxing Day sales are traditionally when shoppers hit the high street to snap up a cut price buy.
But a growing number of people are browsing the aisles online for a bargain instead, to avoid the crowds.
