Bank robber Willie Sutton, when asked why he robbed banks, is reported to have said "Because that's where the money is." While the statement's authenticity is uncertain, its lesson is proven: Scammers and thieves follow the money. And there's plenty of money in health care.

Many scams, such as embezzlement, aren't new. Any time money changes hands there's a possibility some employees will help themselves. But now, with the Internet changing the way we communicate and share information, a new breed of criminal has emerged. From predatory journals that erode the scientific process to phishing and ransomware, there are plenty of dangers to watch for.
