Why should physicians and providers care about the possibility of a ransomware attack? There are several reasons. First, it is disruptive both to patient care and to the revenue cycle. Second, it is costly in terms of time, IT capital, and if the attacker is paid, money. Finally, the time it takes to correct the attack, implement paper charting and communication, and subsequently revise the electronic medical record system can be arduous.

To understand the necessary precautionary measures and what to do in the event of an attack, it is first necessary to identify what ransomware is and how it works. A common definition of ransomware is “a type of malicious software designed to block access to a computer system until a sum of money is paid.”[1] A ransomware attack may target a business or an individual. The two categories of attacks are Denial of Service (“DoS”) and Distributed Denial of Service (“DDoS”). A DoS attack affects a single computer and a single internet connection, while a DDoS attack involves multiple computers and connections. According to PC World, three types of ransomware programs top the list – CTB-Locker, Locky and TeslaCrypt.

A common question that arises is whether or not to pay the ransom in order to have the data returned. The FBI advises not paying the ransom, advice that has been echoed by statistics.

“Kaspersky’s research revealed that small and medium-size businesses were hit the hardest, 42 percent of them falling victim to a ransomware attack over the past 12 months. Of those, one in three paid the ransom, but one in five never got their files back, despite paying. Overall, 67 percent of companies affected by ransomware lost part or all of their corporate data and one in four victims spent several weeks trying to restore access”

This leads us to the best ways to defend against an attack, as well as steps that should be taken if an attack occurs.

Proactive steps include: educating employees about social engineering, phishing and spear phishing, continuously making sure that software updates are installed, creating a layered approach to security defenses, limiting access to the network, making sure that policies and procedures are comprehensive and updated, and ensuring that data is backed up daily.

According to FBI Cyber Division Assistant Director, James Trainor, “These criminals have evolved over time and now bypass the need for an individual to click on a link. They do this by seeding legitimate websites with malicious code, taking advantage of unpatched software on end-user computers.”[2] Hence, recognizing the avenues that cybercriminals use to gain access and taking appropriate administrative, physical, and technical precautions can reduce the risk of an attack.
