On July 28, 2016, US Department of Health and Human Services (HHS) issued guidance (guidance) under the Health Insurance Portability and Accountability Act (HIPAA) on what covered entities and business associates can do to prevent and recover from ransomware attacks. Ransomware attacks can also trigger concerns under state data breach notification laws.
Ransomware is a type of malware (malicious software). It is deployed through devices and systems through spam, phishing messages, websites and email attachments, or it can be directly installed by an attacker who has hacked into a system. In many instances, when a user clicks on the malicious link or opens the attachment, it infects the user’s data. Ransomware attempts to deny access to a user’s data, usually by encrypting the data with a key known only to the hacker who deployed the malware. After the user’s data is encrypted, the ransomware attacker directs the user to pay a ransom in order to receive a decryption key. However, the attacker may also deploy ransomware that destroys or impermissibly transfers information from an information system to a remote location controlled by the attacker. Paying the ransom may result in the attacker providing the key necessary needed to decrypt the information, but it is not guaranteed. In 2016, at least four hospitals have reported attacks by ransomware, but additional attacks are believed to go unreported.
