Hackers attempted to lift patient information over a weeklong period from Sept. 22-29. The data was stored in a third-party system provided by AccuDoc Solutions Inc., which provides billing services to Atrium and about 50 other hospitals and health-care systems.
Compromised information included names, addresses, dates of birth, invoice numbers, account balances, dates of service, insurance policy information and Social Security numbers.
"We are notifying the patients and guarantors who may have been impacted by this incident. We take cybersecurity very seriously, and we’ve worked very hard to determine exactly what happened, and how to prevent it from happening again," Atrium says in a statement.
