ApolloMD Business Services, LLC (ApolloMD), an Atlanta, GA-based provider of integrated, multispecialty physician, APC, and practice management services, has recently disclosed a security incident affecting several of its physician practice clients.

Unusual activity was identified within the ApolloMD network environment on May 22, 2025. An investigation was launched to determine the nature and scope of the activity, and steps were taken to secure its network. Assisted by a third-party cybersecurity firm, ApolloMD learned that an unauthorized third party had access to its network from May 22, 2025, to May 23, 2025. During that time, files containing the electronic protected health information (ePHI) of ApolloMD’s affiliated physicians and practices may have been accessed or acquired.

The file review determined that the information potentially stolen in the incident included names, addresses, dates of birth, diagnoses, provider names, dates of service, treatment information, and health insurance information. A subset of individuals also had their Social Security numbers exposed. ApolloMD notified the affected physicians and practices between July 21, 2025, and September 11, 2025, and notification letters started to be mailed to the affected individuals on September 17, 2025. ApolloMD has confirmed that complimentary credit monitoring and identity theft protection services are being offered to individuals whose Social Security numbers were exposed.

ApolloMD did not disclose details about the nature of the attack; however, the Qilin ransomware group claimed responsibility and added ApolloMD to its dark web data leak site in June 2025. Qilin claimed to have exfiltrated a large amount of sensitive data and said it would release the data on June 16, 2025, if the ransom was not paid. At the time of writing, the Qilin data leak site is not accessible, and other sites operated by the group are protected by a login. Qilin has been the most active ransomware group in four of the five months up to August 2025, according to cybersecurity firm Cyble, having claimed more than twice the number of victims as the second most active group. It should be stated that ransomware groups have been known to fabricate claims on their data leak sites.

The total number of affected individuals has not been made public by ApolloMD at this stage, and the data breach is not currently shown on the HHS’ Office for Civil Rights website.

ApolloMD is issuing notification letters on behalf of the following covered entity clients.

Sturgis Hospital, a rural critical access hospital in the Northern Black Hills in Michigan, has recently reported two security incidents to the HHS’ Office for Civil Rights, both of which have potentially affected up to 77,771 individuals. The first incident was identified in December 2024 when unauthorized activity was observed in part of its computer network. Third-party cybersecurity experts were engaged to investigate the incident and determine the nature and scope of the unauthorized activity. Unauthorized access was confirmed, the incident was remediated, and the exposed files were reviewed to determine the individuals affected and the types of data involved.

The investigation and file review had not concluded when further unauthorized network activity was detected in June 2025. A separate investigation was launched into the second incident, with assistance provided by third-party experts. Based on the two investigations, Sturgis Hospital concluded that there was potentially unauthorized access to patient and employee information and files containing sensitive patient and employee data may have been exfiltrated from its network.

The file review confirmed that the exposed information included names, contact information, government identification numbers such as Social Security numbers, financial account information, health insurance information, and clinical information, such as treatment information, prescriptions, and other medical information. Sturgis Hospital said it worked with third-party cybersecurity experts to secure its systems and implement additional cybersecurity measures to prevent similar incidents in the future. The affected individuals have been offered complimentary subscriptions to credit monitoring and identity theft protection services. Law enforcement was notified about both incidents, and while law enforcement did not request delaying notifications, it has taken some time to investigate the incidents. Notification letters are now being mailed to the affected individuals.

Only a few weeks ago, Aspire Rural Health System, another rural healthcare provider in Michigan, announced a cyberattack and data breach that affected up to 140,000 individuals, and Endless Mountains Health Systems in Montrose, Pennsylvania, experienced a suspected ransomware attack in March 2025. Many rural healthcare providers are struggling to remain viable, and in some cases are providing care well below the cost of providing their healthcare services. With limited funds available for cybersecurity and difficulties attracting skilled cybersecurity staff, they can be vulnerable to cyberattacks. The HHS has recently confirmed that $50 billion is being made available in grants to transform rural healthcare over the next five years, one of the goals of which is to help rural healthcare providers invest in technology and improve cybersecurity.
