SuperCare Health Data Breach Impacts Over 300,000 People

California-based respiratory care provider SuperCare Health recently disclosed a data breach affecting more than 300,000 individuals.

In a data security notice posted on its website, SuperCare said the intrusion was discovered on July 27, 2021, when it noticed unauthorized activity on some systems. An investigation revealed that someone had access to certain systems between July 23 and July 27, 2021.

However, it took the company until February 4, 2022, to determine that the exposed files contained patient information, including name, address, date of birth, hospital or medical group, medical record number, patient account number, health-related information, and claim information. In some cases, social security numbers and driver’s license numbers were also stored in the compromised files.

“Please note that to date, we have no reason to believe that any information was published, shared, or misused as a result of this incident,” the company said.

SuperCare notified impacted individuals about the incident only on March 25.

The company told the US Department of Health and Human Services that the breach has impacted 318,379 people. This is currently in the top 50 healthcare breaches reported in the past two years, based on the number of affected individuals.

Several healthcare organizations reported suffering major data breaches in the past months. The list includes Monongalia Health System (400,000 impacted), South Denver Cardiology Associates (287,000), Norwood Clinic (228,000), and Broward Health (1.3 million).

The Health Department last week issued an alert for organizations in the healthcare sector to warn them about the impact of a recent attack by the cybercrime group known as Lapsus$.

The hackers targeted several major companies in the past few months, including Samsung, NVIDIA, Vodafone, Ubisoft, GlobantMicrosoft and Okta. The group steals data — in many cases source code — and threatens to make it public unless they get paid.

The Health Department’s alert says it’s aware of healthcare organizations compromised as part of the Okta attack — Okta has confirmed that more than 300 of its customers were impacted by the breach.

Several alleged members of the Lapsus$ group have been identified by UK police and some of them have been charged.
