Earlier this month, Purity Cylinder/Airway Oxygen in Michigan reported a breach to the Vermont Attorney General’s Office.
According to their notification, on April 18, they discovered that ransomware had been installed on their network.
There was no evidence, they say, that any protected health information was actually accessed or acquired, but they notified those who were potentially affected.
Today, the incident appeared on HHS’s public breach tool as affecting 500,000.
