Phishing attacks are now accounting for over 50 per cent of all virus threats.
According to research by Network Box, this is the highest percentage of malware so far this year, up from 33 per cent in February.
Simon Heron, internet security analyst at Network Box, said: “A poor economy means greater numbers of disgruntled employees, desperate individuals trying to make money and increased opportunity as we become more technologically enabled.
“It really is time to review the basics of corporate security. Whenever an economy is depressed, the instances of cybercrime, just like burglaries, increase. Time spent now on educating employees, checking your internet use policy, and applying some common sense security measures will pay dividends through the coming months.”
