Veradigm and ApolloMD, both healthcare software and services vendors, reported data breaches to regulators after unauthorized actors accessed sensitive patient data through compromised customer credentials. Veradigm disclosed that the breach originated from a credential obtained from a customer, which was then used to access a Veradigm storage unit containing patient information. The incident, which occurred in December 2024 but was only recently discovered, highlights the ongoing risks associated with third-party vendor security in the healthcare sector. Both companies are notifying regulators and affected parties as required, and the breaches underscore the need for robust third-party risk management and timely breach notification.

Healthcare technology company **Veradigm** disclosed that an unauthorized party used credentials stolen from a third-party vendor to access a customer-services API and download patient personal data belonging to a limited subset of customers. Some records contained Social Security numbers, but Veradigm said no clinical or medical information was exposed and that its internal network, servers, databases, and operations were not accessed or disrupted. Veradigm activated its incident-response process, notified law enforcement, and is investigating the scope of the exposure while notifying affected individuals and offering credit monitoring where appropriate. The Gentlemen ransomware group claimed responsibility and alleged it holds 3.5 million patient records, though Veradigm has not attributed the intrusion or verified that claim.

ApolloMD, a US-based healthcare services and practice management provider and HIPAA business associate, disclosed that a May 2025 cyberattack led to unauthorized access to its IT environment and potential theft of patient data affecting **626,540** individuals. ApolloMD reported detecting unusual activity on **May 22, 2025**, and its investigation concluded an unauthorized party accessed systems between **May 22–23, 2025**, including files tied to patients treated by affiliated physicians and practices; the incident was later reflected in US HHS breach reporting. Exposed data varied by individual but included **names, dates of birth, addresses, diagnoses, treatment details/dates of service, provider names, health insurance information**, and for some, **Social Security numbers**. Reporting also linked the incident to the **Qilin ransomware** group, which publicly listed ApolloMD on its leak site in June 2025 and claimed exfiltration of **238 GB** (posting limited proof screenshots not showing patient data); ApolloMD’s public notice did not confirm ransomware, encryption, or a ransom demand. ApolloMD notified affected client practices between **July–September 2025**, issued patient letters in mid-September 2025, and posted a substitute notice later that month, including a list of impacted managed physician practices.
