Healthcare Data Breach Report in August 2021

August 2021 had 44% less number of reported healthcare data breaches. Healthcare providers, health plans, and their business associates reported 38 healthcare data breaches involving 500 or more records. Including August’s reported data breaches, the total number of healthcare data breaches for the past 12 months is 707. The reported data breaches for 2021 are 440.

Although there was a noticeable drop in the number of reported breaches, the breached healthcare records numbering 5,120,289 is higher than the average in 12 months, which is 3.94 million per month. The high number was mostly because of two big ransomware attacks on University Medical Center Southern Nevada and St. Joseph’s/Candler Health System, which included 2.8 million healthcare records put together.

Biggest Healthcare Data Breaches Reported in August 2021

Ransomware groups went on targeting the healthcare sector in August. A number of the attacks documented in August resulted in postponed appointments and some patients were taken to other facilities to get treatment.

It is currently typical for attackers to exfiltrate sensitive information before using ransomware and then require ransom payment in exchange for the keys to decrypt data and to avoid exposure of the stolen data. Although a number of big ransomware operations like the DarkSide and the Sodinokibi/REvil seem to have been shut down, many other campaigns took their place. For example, the Vice Society and Hive ransomware gangs targeted the healthcare industry, and this September, the Health Sector Cybersecurity Coordination Center (HC3) released a notice to the health and public health industry regarding a growing threat of BlackMatter ransomware attacks. Thankfully, this month, the Sodinokibi/REvil ransomware gang victims were given the chance to get back encrypted files without charge. Bitdefender published a free Sodinokibi/REvil decryptor the past week.

In August, healthcare providers reported three big ransomware attacks that affected substantial amounts of patient information. DuPage Medical Group experienced a ransomware attack wherein 655,384 patients’ protected health information (PHI) were potentially compromised, whereas the attack on University Medical Center Southern Nevada impacted 1.3 million patients and the St. Joseph’s/Candler Health System attack affected the PHI of 1.4 million individuals.
