Hacking medical data has become a booming business, and attacks against hospitals are up 600 percent in 2014, a security company CEO told CNBC.
The increase in data-sharing, and the growth of the Internet of everything may be good for medicine, but it's creating a security nightmare for the health-care industry, said John McCormack, chief executive of Websense.
"Medical information is incredibly valuable, it's where the money is at," he said. "There's been a huge spike in hospital attacks."
One credit card number costs mere pennies on the black market, but one medical record can be worth about $100, making it a much more appealing target, he said.
