AdaptHealth Discloses Patient Data Theft After Contractor Account Compromise

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.
