A Kansas medical group will pay $1.2 million to settle proposed class action litigation involving an attack that compromised the sensitive data of nearly 256,000 individuals. The Rhysida ransomware operation claimed responsibility.

Under the court-approved preliminary settlement, victims can claim a one-time cash payment of $10 or submit receipts to recoup out-of-pocket losses up to $5,000. Plaintiff attorneys are asking for half of the settlement money be set aside for their fees and expenses.
Sunflower Medical additionally agreed to provide class counsel with “a confidential declaration regarding additional cybersecurity safeguards it implemented to reasonably mitigate the risk of another data breach.” The group provides services to Kansas and Missouri patients, including family healthcare, urgent care, internal medicine and telehealth from several offices.
A final approval hearing for the settlement was set by a Missouri state court for March 6.
As of Tuesday, Rhysida still lists Sunflower Medical on its darkweb site as a Jan. 7 victim. The Russian-speaking operations claims to have stolen an SQL database with more than 3 terabytes of the practice’s data, including more than 400,000 driver’s licenses, insurance cards and Social Security numbers.
A putative sample of stolen data includes images of driver’s licenses, health insurance cards and other records that appear to contain the names and other identifiers of patients.
Sunflower reported the breach to federal and state regulators in March, saying the incident affected nearly 221,000 individuals. Settlement documents indicate that Sunflower’s final tally of the affected class size is 255,734 individuals (see: Rhysida Hacking Group Strikes More Healthcare Providers).
Sunflower in its breach notification letter said that on Jan. 7 it learned that an unauthorized third party had potentially accessed Sunflower’s systems and acquired copies of certain files.
An investigation determined that an unknown third party accessed Sunflower’s systems on or about Dec. 15, 2024, and acquired copies of certain files from the medical group’s systems.
The consolidated lawsuit complaint against Sunflower Medical alleged a number of claims including negligence, breach of fiduciary duty and violations of certain state laws.
Neither Sunflower Medical Group nor attorneys representing the class members immediately responded to Information Security Media Group’s request for comment on the settlement and additional details about the hacking incident.
