“Symantec estimates more than 868,206 New Zealanders were scammed this year, resulting in $NZ288.2 million in direct financial losses plus $NZ 337.3 million to resolve and recover.”

through phishing attacks, advanced fee frauds and romance scams.
It alleges cybercrime and recovery worldwide costs $US388 billion – $US100 billion more than the global black market in marijuana, cocaine and heroin combined – with around a million victims every day.

One international survey showed 41 percent of adults did not have current security software; less than half checked credit card statements for potential fraud and 61 percent failed to use complex passwords or regularly change them to protect phones or PCs.
