Medtronic disclosed that unauthorized actors accessed certain corporate IT systems between April 13 and April 19, exposing personal and health-related information tied to 3,834,294 individuals. The company said the incident was detected after unusual activity on April 15 and attributed in public reporting to the ShinyHunters extortion group, which claimed to have stolen about 9 million records and briefly listed Medtronic on its Tor-based leak site before the post disappeared. Exposed data may include names, contact details, dates of birth, Social Security numbers, and other health-related information.
Medtronic said it found no impact on medical devices, patient safety, hospital customer networks, manufacturing and distribution operations, financial systems, or care delivery, and added that it has no evidence the stolen data was publicly released online. The company has engaged external cybersecurity experts, notified law enforcement and regulators, and is warning affected people to watch for phishing, social engineering, and unauthorized account activity while offering 24 months of credit monitoring, dark web monitoring, and identity theft recovery services.

Medtronic said an unauthorized party accessed data in portions of its corporate IT environment and that it has contained the incident, activated response procedures, and engaged external cybersecurity experts. The company said it has not identified any impact on **products**, **patient safety**, customer connections, manufacturing and distribution operations, financial reporting systems, or its ability to meet patient needs, stressing that corporate IT, product, manufacturing, and hospital customer networks are segmented. The disclosure followed extortion claims tied to **ShinyHunters**, which said it stole more than **9 million records** containing personally identifiable information along with terabytes of internal corporate data and briefly listed Medtronic on its leak site before the entry disappeared. Medtronic said its investigation is ongoing to determine whether personal data was accessed and that it will notify affected individuals and provide support services if exposure is confirmed, while separate reporting also linked the incident to **Handala**, underscoring uncertainty around attribution even as the breach itself has been confirmed.

Multiple healthcare entities reported **unauthorized access and patient data exposure**, with incidents spanning direct provider compromises and third-party vendor breaches. **Insight Hospital and Medical Center (Chicago)** disclosed suspicious activity in its IT environment, with investigators confirming **unauthorized network access from Aug 22 to Sep 11, 2025**; the organization said the review is ongoing but potentially impacted data includes **names, DOB, SSNs, passport numbers, financial account data, treatment information, and insurance details**. Two extortion groups publicly claimed responsibility: **LockBit** alleged theft of ~`200 GB` and **Termite** claimed `360 GB`, stating it leaked data in late February 2026. In France, attackers stole about **15.8 million administrative files** after breaching health-ministry software supplier **Cegedim Santé**, impacting its *MonLogicielMedical (MLM)* product used by thousands of doctors; the stolen data reportedly included **identity and contact details**, and in a smaller subset (~**165,000** files) **free-text doctors’ notes** that in limited cases contained sensitive medical-history details. Separately, **OCAT, LLC d/b/a Evoke Wellness at Hilliard** updated a breach notification describing **unauthorized network activity** and potential access to patient information; reporting also tied the matter to an **insider misuse** investigation in which a former employee allegedly accessed and sold patient data, though public filings contained **inconsistent timelines** about when the underlying incident occurred and when it was discovered.

AdaptHealth disclosed a material cybersecurity incident after attackers used social engineering against a third-party contractor, compromised the contractor’s credentials, and accessed the company’s cloud-based business applications. The intrusion exposed internal patient management systems, document storage platforms, external electronic health record portals, and a stored password file tied to insurance billing, with patient personally identifiable information and protected health information believed to have been stolen. The company said the attacker contacted it on June 15 to disclose the theft, and it later determined the breach was material enough to report to the SEC. AdaptHealth said it disabled the contractor account, reset credentials, added access controls, engaged third-party cybersecurity experts, and notified law enforcement while the investigation continues. The company reported that operations and patient services were not disrupted, the total number of affected individuals is still unknown, and Social Security numbers, financial account information, and payment card data are not believed to have been stored in the compromised systems. Reporting also indicated the activity may be consistent with a data-theft-and-extortion attempt linked to **ShinyHunters**, which allegedly listed AdaptHealth on a leak site and threatened to publish the stolen data if no ransom is paid.
