In response to the increasing prevalence of ransomware cyber-attacks by hackers on electronic health information systems in hospitals and medical practices, the Department of Health and Human Services (HHS) Office for Civil Rights (OCR) announced on Monday July 11, 2016 its publication of new HIPAA guidance
on ransomware (aEURoeRansomware GuidanceaEUR?). According to OCR:
Ransomware is a type of malware (or malicious software) that encrypts data with a key known only to the hacker and makes the data inaccessible to authorized users. After the data is encrypted, the hacker demands that authorized users pay a ransom (usually in a cryptocurrency such as Bitcoin to maintain anonymity) in order to obtain a key to decrypt the data.
Notably, the HIPAA Security Rule already requires implementation of security measures to help covered entities and business associates prevent the introduction of malware (e.g., ransomware) into their systems, and to implement policies and procedures to assist in responding to ransomware attacks. The Ransomware Guidance addresses, among other areas, how to implement security measures in order to prevent, mitigate the chances of, or even recover from ransomware attacks. Not surprisingly, conducting a risk analysis (or risk assessment) is at the core of covered entities and business associates implementing security management processes as required by the HIPAA Security Rule. The Ransomware Guidance further notes that maintaining an overall contingency plan, as required by the Security Rule, that includes disaster recovery planning, emergency operations planning and frequent backups of data can also help covered entities and business associates respond to and recover from malware infections, including ransomware attacks.
In addition, the Ransomware Guidance states that ransomware attacks against a covered entity or business associate can be considered a breach under the HIPAA Rules. Specifically, the Ransomware Guidance provides, aEURoe[w]hen electronic protected health information (ePHI) is encrypted as the result of a ransomware attack, a breach has occurred because the ePHI encrypted by the ransomware was acquired (i.e. unauthorized individuals have taken possession or control of the information), and thus is a aEUR~disclosureaEUR(TM) not permitted under the HIPAA Privacy Rule.aEUR? Therefore, unless it can be shown that there is a low probability that the PHI involved in the ransomware attack has been compromised based on the factors in the Breach Notification Rule, a breach is presumed to have occurred, which would trigger the applicable breach notification provisions.
Even before OCRaEUR(TM)s publication of the Ransomware Guidance, in late June the Secretary of HHS sent a letter
(aEURoeLetteraEUR?) to the attention of chief executive officers at health care entities addressing the threat of ransomware. The Secretary attached interagency guidance to the Letter containing best practices and mitigation strategies integral to combatting ransomware incidents.
Ransomware is immediately disruptive to the day-to-day operation of businesses, as seen by its impact earlier this year on health care systems like MedStar in Washington, D.C. and Hollywood Presbyterian Medical Center in Los Angeles (aEURoeHPMCaEUR?), resulting for example, in HPMC paying 40 Bitcoins (approximately $17,000) to regain control of its computer system. Although the Ransomware Guidance does not address whether payment or ransom should be paid to regain access to computer systems, the interagency guidance attached to the Letter advises against paying hackers because, among other reasons, paying a ransom doesnaEUR(TM)t necessarily guarantee that an entity will regain access to its system. The Ransomware Guidance does recommend that an entity victimized by a ransomware attack contact its local FBI or United States Secret Service field office.
