Airway Oxygen: 500,000 affected individuals
The mid-Michigan vendor suffered a ransomware attack in April that apparently came from an off-shore location. The company was unusually candid in its explanation of the breach to affected individuals. The notification letter included an expansive Q&A covering who was responsible for the breach, how it was discovered, how long hackers were in the system and if the hack could have been prevented. However, the company acknowledged it would not comment on whether ransom was paid.
