Sunflower Medical Group Data Breach Exposes Over 220,000 Patients' Information

Sunflower Medical Group, a multi-specialty healthcare provider with four care centers in Kansas City, Lenexa, and Roeland Park, Kansas, recently confirmed a major data breach that compromised the sensitive personal and health information of 220,968 individuals. The breach, attributed to a cyberattack by the Rhysida ransomware group, has raised serious concerns about data security within the healthcare sector.

‍

Details of the Data Breach

Suspicious network activity was first detected on January 7, 2025, prompting an investigation by cybersecurity experts. Findings revealed that an unauthorized actor had accessed Sunflower Medical Group’s network for nearly a month—between December 15, 2024, and January 7, 2025—during which time files were exfiltrated from the system, some containing sensitive patient data.

‍

What Information Was Compromised?

The breach exposed a range of personal and protected health information (PHI), including:

• Full names
• Addresses
• Dates of birth
• Social Security numbers
• Driver’s license numbers
• Medical records and health information
• Health insurance details

While Sunflower Medical Group has not reported any known misuse of the stolen data, it has offered complimentary credit monitoring and identity theft protection to individuals whose Social Security numbers or driver’s license numbers were compromised.

‍

Who Is Behind the Attack?

The Rhysida ransomware group, a notorious cybercriminal organization known for targeting healthcare providers, has claimed responsibility for this breach. The group claims to have exfiltrated a 3-terabyte SQL database containing data on approximately 400,000 individuals—a number that may include duplicate entries.

Rhysida has been responsible for numerous high-profile attacks on healthcare organizations, including breaches at Community Care Alliance and Ann & Robert H. Lurie Children’s Hospital in Chicago.
