An anonymous reader writes "Americans feel most vulnerable about the loss or theft of their personal or financial information, according to a national survey. 54% of Americans said the prospect of losing this data 'extremely concerned' them. Losing personal or financial information ranked similar to concern over job loss and not being able to provide healthcare for their family. In terms of specific risks within the online threat landscape, identity theft ranked as the chief fear. Nearly a third of Americans reported identity theft as their greatest concern to personal safety and security on the Internet. The fear of someone hacking into their financial information or accounts ranked a close second, with a quarter of Americans listing it as their greatest worry."
