Sixteen per cent of social network users in New Zealand have been victims of social cybercrime and 13 per cent reported someone had hacked into their profile and pretended to be them. The two main forms of the online scams are either for monetary gain or to collect personal details to "create mischief".
Norton's annual cybercrime report estimated more than 900,000 New Zealanders fell victim to online criminal activity in the past 12 months, totalling more than $462 million in direct financial losses.
The worldwide survey interviewed a representational group of 500 New Zealanders about their cybercrime experiences and multiplied it to match the population.
Year on year they had seen a doubling in the number of threats.
Mr Freer said people needed to be aware of the fact that cybercrime had moved to social networks and mobile devices.
New Zealanders also needed to be more vigilant with changing their passwords and choosing secure combinations. In the past year, 34 per cent have been notified to change their password because it or their privacy had been breached.
NetSafe's chief executive Martin Cocker said the most secure passwords included a combination of letters, numbers and symbols.
Not stranded, just hacked
An anonymous overseas hacker broke into Reuben Simpson's email and PayPal accounts, sending hundreds of messages to all of his contacts.
They were told to send money because Mr Simpson was stranded in England and needed to get home.
"At first I had no idea what was going on," he said.
The 19-year-old, from Beach Haven, had the bright idea to search his email account on Google and found it posted, along with his password, on a foreign website.
Mr Simpson, a university student and jazz singer, was one of thousands who had their privacy breached by Google in 2009, the time of his cyber attack.
Once he worked out what had happened, he quickly contacted Google so he could regain access to his gmail account and called PayPal. He didn't lose any money and none of his con-tacts believed he was stuck in England.
