Fresenius Medical Care Hit By Major Data Breach: Half A Million Patients Potentially Affected

Fresenius Medical Care FMS said in a filing that one of its units was affected by a security incident where an intruder claimed to have stolen data.

Cardiovascular Consultants, Ltd. (CVC), a subsidiary located in the U.S., is affected. The incident may have affected approximately 500,000 patients, former patients, guarantors, and 200 staff across several states, U.S. territories, and four countries.

The incident also impacted various applications and files that contained sensitive employee information.

"We have engaged a consumer credit reporting agency to facilitate patient notifications, call center services and credit monitoring of the affected parties on our behalf," the German company said. 

The security incident affected the electronic medical record and data warehouse containing information on current and former CVC patients and others.

"In addition, we are currently investigating the impact of this security incident on another subsidiary, Fresenius Vascular Care, Inc., located in the United States," Fresenius Medical Care said.

The investigation has determined that specific systems were accessed and data were encrypted and stolen by the intruder. 

This investigation is still ongoing. However, the company does not expect the incident to have a material impact on its financial condition or results of operations.
