Cybercrime claimed 431 million adult victims last year and cost USD 114 billion, according to a report published on Wednesday.

The Norton Cybercrime Report 2011 said over 74 million people in the United States were cybercrime victims last year, suffering USD 32 billion in direct financial losses.

Cybercrime cost China around USD 25 billion, Brazil USD 15 billion and India USD 4 billion in the past 12 months, said the report from computer security firm Symantec, maker of the Norton anti-virus software.

According to the report, more than two-thirds of online adults -- 69 per cent -- have been victims of cybercrime at some point in their lives, resulting in more than one million cybercrime victims a day.

Cybercrime rates were even higher in China and South Africa. Eighty-five per cent of Chinese respondents to the Norton survey and 84 per cent of South Africans said they have been victims of cybercrime.

The report found a growing threat from cybercrime on mobile phones. Ten per cent of adults online have experienced cybercrime on their mobile phones and the number of reported new mobile operating system vulnerabilities increased from 115 in 2009 to 163 in 2010.

"There is a serious disconnect in how people view the threat of cybercrime," said Adam Palmer, Norton lead cybersecurity advisor. "Cybercrime is much more prevalent than people realise".

"Over the past 12 months, three times as many adults surveyed have suffered from online crime versus offline crime, yet less than a third of respondents think they are more likely to become a victim of cybercrime than physical world crime in the next year," Palmer said. For the survey, interviews were conducted with nearly 20,000 people in 24 countries, Symantec said.
