Another hit for health IT—now hackers hold hospitals hostage?

The nature of health care data security breaches is changing. Whereas the majority of lapses in health care information security were once caused by the loss and theft of devices, the greatest security threat to health care consumers and health care providers is now happening through large-scale hacks. The shift has left the industry exposed. The Institute for Critical Infrastructure Technology warns that among all of the nation’s critical infrastructures, the most vulnerable is the health care sector. The warnings aren’t empty, in January 2015, a breach of Anthem, Inc. allowed hackers access to the information of 80 million Americans. Three months later, another 11 million individuals had information stolen when health insurer Premera Blue Cross was hacked. Now, hackers have taken things one step stranger by shutting down a California hospital’s internal computer system for a ransom of almost $3.7 million.

New trend

According to the 2016 Health Care Breach Report from security company Bitglass, 98 percent of leaked healthcare records were exposed as a result of large-scale hacks, like the Anthem and Premera hacks. Although the enormity of those breaches might at first suggest that a few large breaches skewed the average results, the report also noted that even when the six largest breaches are excluded, hacking-related incidents still accounted for the majority of leaked health care data. The breach report explained that 111 million people were affected by data loss. Some of the data lost included names, addresses, dates of birth, social security numbers, and medical claims information. Why are hackers targeting health care data? The obvious answer: money. According to a Ponemon Institute report, in general, the average cost per lost or stolen record is $154, but when a record is stolen from a health care organization, the number rises to $363.


The trend is alarming, and the security threat does not appear to be stopping at conventional security hacks. The California hospital under ransom—Hollywood Presbyterian—was shut down by a type of malicious software known as ransomware. Like other malware, the software identifies weakness in a computer system and then encrypts data, which can only then be unencrypted with a key code. The hackers of Hollywood Presbyterian have placed a price on that keycode—9,000 bitcoin, worth about $3.7 million. According to the hospital, the hack has impacted the provider’s ability to deliver care by interrupting email and access to certain systems. According to the hospital, the hack has not compromised patient medical records. Ransomware has been used before. In fact, since its emergence in 2013, 56 types of ransomware have been used.

What is next?

Some commentators are calling hackers “cyber barbarians” and warning that hacks could result in the actual loss of life. Although the scope of the threat is debatable, there is no dispute that a very real change is happening in the world of health care information security. While security experts say that the threats are addressable and, in some cases, preventable, health care organizations are facing new challenges. Whether they are called hostage takers, barbarians, or criminals, hackers are posing a real threat to private and sensitive health data. The question now is two-fold: (1) what can be done to address and stop the current breaches? and (2) what will the hackers attack with next?
