In this session, we present findings from a long term security research study in healthcare, in which we discovered that adversaries can deploy cyber attacks that result in harm or fatality to patients. Over the course of 24 months, we investigated 12 hospitals, 2 healthcare data facilities, 2 medical devices and host of supporting applications and technologies. Our focus was to (a) determine the feasibility of attacks against patient health, (b) determine the contextual issues from both technical and business perspectives, and (c) articulate the solution.
