Medusa Ransomware Group Exposes Data Stolen from American Renal Associates

American Renal Associates (ARA) experienced an attack by the Medusa ransomware group. ARA is a dialysis services provider in the United States and cares for patients battling end-stage renal disease. Before ARA announced the ransomware attack, the Medusa ransomware group already leaked information purportedly stolen in the cyberattack. The attack happened on March 2, 2024, and impacted many computers.

Upon investigation of the leaked information by Marco A. De Felice, the Medusa group stole approximately 5TB of information including the protected health information (PHI) of about 37,700 patients. The leaked data included patient names, birth dates, telephone numbers, email addresses, health records, copies of driver’s licenses and passports, Social Security numbers, medical insurance details, and company information.

Family Health Center Cyberattack

Family Health Center located in Kalamazoo, MI, has reported a cyberattack that resulted in system disruption and affected the operation and accessibility of selected systems. On January 25, 2024, immediate action was undertaken to control the attack and stop more unauthorized access. A third-party cybersecurity company conducted a forensic investigation.

The investigation uncovered proof of unauthorized access to records that included patient data. The analysis of those records revealed that they included employee data like names, addresses, medical insurance data, and Social Security numbers, and patient data like first and last names, and medical details. Family Health Center has submitted the breach report to the HHS’ Office for Civil Rights as impacting 3,240 people and stated it has taken action to enhance security by extending multi-factor authentication and improving tracking of its system for suspicious activity.
