Airway Oxygen, a Wyoming, Mich.-based home medical equipment supplier, experienced a ransomware attack affecting 500,000 individuals, according to HHS' Office for Civil Rights breach portal.
The company learned April 18 that a cyberattacker gained access to its technical infrastructure and installed ransomware, according to a letter delivered to customers whose protected health information was on the computer network. This information might have included names, dates of birth, diagnosis and health insurance information, among other data.
Airway Oxygen officials have no evidence any protected health information was accessed or acquired, according to the letter. The letter detailed information about credit reports and fraud alerts, and specified the company had reported the incident to the FBI. The company has established a dedicated call line and hired a cybersecurity firm to assess the impact of the breach.
