$19,000 was stolen recently from a bank in New Jersey via electronic transfer. These incidents occur more often than you’d think, and affect both businesses and individuals. The end of the article talks about measures they’re taking to prevent this in the future, mainly using an dedicated computer for banking that isn’t used for web surfing, email, file transfers, or anything other than banking. A few years ago people would have laughed at air-gaping a system like the Department Of Defense does, but it’s becoming a more popular way to protect ultra-sensitive data. I’ve recommended similar solutions (including virtual machines) in situations where the cost of stolen data or computer downtime greatly outweighs the inconvenience or price of the solution.
