Insiders comprise more than half of cyberattackers in healthcare

Healthcare is the only industry vertical with more insiders causing data breaches, as opposed to external actors or partners, according to Verizon's 2018 Data Breach Investigations Report.

To compile the report, Verizon reviewed data security incidents across nine industries between Nov. 1, 2016, and Oct. 31, 2017. In the healthcare industry, Verizon identified 750 breach incidents, 536 of which confirmed data disclosure.
