Medical equipment provider AdaptHealth suffered a cyberattack in which criminals used social engineering to compromise a third-party contractor and gain access to the company's cloud systems. Attackers stole sensitive patient data, including personally identifiable information, protected health information, and a password file linked to insurance billing, though Social Security numbers and payment details are believed to be unaffected. AdaptHealth disclosed the breach to the SEC on June 27, deeming it material due to the potential volume of data at risk, while investigations into the full scope of the incident are ongoing.
