Ars Technica reports on a new study of data breaches that found criminal activity and malicious attacks are increasingly behind data breaches. The Ponemon Institute survey--which was sponsored by Symantec and followed 49 organizations with more than 400 IT, compliance and security professionals--found that such attacks accounted for 37 percent of data breaches last year, up six percent from the year before. More than two-thirds of the attacks were electronic. Twenty-eight percent involved physical theft. Additionally, 33 percent of malicious attacks involved company insiders. Meanwhile, a second study found that the cost of breaches is falling for the first time in seven years.
