Community Clinic of Maui discloses a data breach following May Lockbit ransomware attack

Community Clinic of Maui experienced a data breach impacting over 120,000 people following a LockBit ransomware attack.

In May, the Community Clinic of Maui experienced a major IT outage that impacted thousands of patients following a cyber attack. In June, the Lockbit ransomware gang took credit for the attack.

The Community Clinic of Maui, also known as Mālama I Ke Ola Health Center, is a nonprofit healthcare organization dedicated to serving the Maui community. The clinic provides a range of services including primary care, dental care, and mental health support. The clinic operates with a mission to deliver culturally sensitive healthcare, emphasizing education, prevention, and advocacy regardless of patients’ ability to pay.

The cyber attack impacted the systems at the health center in Wailuku for more than two weeks.

Mālama investigated the security breach with external cybersecurity professionals, and on August 7, 2024, the experts determined that personal data may ‘have been subject to unauthorized access and acquisition between May 4, 2024 and May 7, 2024.’

The Community Clinic of Maui now discloses a data breach impacting 123882 people following the LockBit ransomware attack.

“The personal information that was potentially impacted included first and last names with one or more of the following identifiers: Social Security Number, Date Of Birth, Driver’s License Number / State Id Number, Passport Number, Financial Account Number, Routing Number, Bank Name, Credit / Debit Card Number, Card CVV Expiration Date, Pin/Security Code, Login Information, Medical Diagnosis, Clinical Information, Medical Treatment/Procedure Information, Treatment Type, Treatment Location, Treatment Cost Information, Doctor’s Name, Medical Record Number, Patient Account Number, Prescription Information and/ or Biometric Data. Mālama has no evidence that any personal information has been or will be misused for identity theft as a direct result of this incident.” reads the notice of breach published by Malama.

Starting on September 26, 2024, Mālama notified affected individuals and offered complimentary credit monitoring to those whose Social Security numbers were potentially exposed.

“On May 7, 2024, Malama experienced a cybersecurity incident that impacted connectivity to our network.” reads the data breach notification letter shared with the Maine Attorney General. “Upon learning of this issue, we immediately commenced a prompt and thorough investigation. We also notified law enforcement. As part of our investigation, we have been working very closely with external cybersecurity professionals experienced in handling these types of incidents. After an extensive forensic investigation and comprehensive document review, on August 7, 2024, we determined your personal data may have been subject to unauthorized access and acquisition between May 4, 2024 and May 7, 2024.”

The Community Clinic of Maui is unaware of any misuse of the compromised data.

In July, the Lockbit ransomware gang breached the Fairfield Memorial Hospital in Illinois. Unfortunately, the ransomware group claimed the hack of other hospitals in the same period. The extortion group also claimed the hack of the Merryman House Domestic Crisis Center, and the Florida Department of Health.

Healthcare infrastructure in the US continues to be under attack, in February the Lurie Children’s Hospital in Chicago took IT systems offline after a cyberattack. The security incident severely impacted normal operations also causing the delay of medical care.

Lurie Children’s Hospital is one of the top pediatric hospitals in the United States.

In early November 2023, the Cogdell Memorial Hospital (Scurry County Hospital District) announced it was experiencing a computer network incident that prevented the hospital from accessing some of its systems and severely limiting the operability of its phone system. The hospital immediately removed network connectivity and continued to provide most routine services.

The facility operates as a Critical Access Hospital and a Rural Health Clinic serving rural West Texas.

In November 2023, the Lorenz extortion group leaked the data stolen from the Texas-based Cogdell Memorial Hospital.

Cyber attacks against hospitals are very dangerous, and despite major ransomware gangs imposing restrictions on their affiliates to avoid targeting them, many incidents have recently made headlines.
