Five biggest data breaches in history

According to the data collected by the Breach Level Index (BLI) database, 974 data breaches occurred worldwide in the first half of 2016, up 15 percent from the 844 breaches during the previous six months (July to December 2015). More than 554 million data records were lost or stolen in the first half of 2016, compared with some 424 million lost or stolen during the previous six months. That represents a dramatic increase of 31 percent.

The trend in which the theft of personal identifiable information has continued to increase has dominated the headlines over the last six months.
