From the HHS Ransomware Fact Sheet:

A recent U.S. Government interagency report indicates that, on average, there have been 4,000 daily ransomware attacks since early 2016 (a 300% increase over the 1,000 daily ransomware attacks reported in 2015).1 Ransomware exploits human and technical weaknesses to gain access to an organization’s technical infrastructure in order to deny the organization access to its own data by encrypting that data.

From the OCR website: 

We are experiencing an explosion of technology using data about the health of individuals in innovative ways to improve health outcomes. Building privacy and security protections into technology products enhances their value by providing some assurance to users that the information is safe and secure and will be used and disclosed only as approved or expected. Such protections are sometimes required by federal and state laws, including the HIPAA Privacy, Security and Breach Notification Rules.
