Millions of people's personal information is at risk after hackers targeted a hospital network.
Community Health Systems Monday announced the breach.
The organization operates 206 hospitals in 29 states across the country, including Kosciusko Community Hospital in Warsaw.
The network also runs eight other hospitals in the state.
It says hackers in China have stolen data on 4.5 million patients.
The breach happened sometime in April and June this year.
The hackers accessed patients' names, Social Security numbers, addresses and phone numbers.
No credit card or medical records were stolen.
The hackers may have been going after a specific target, like company executives, and used a method called "advanced persistent threat."
Anyone who received treatment from a network-owned hospital in the last five years is affected.
People who were referred there by a doctor are also impacted.
The large data breach puts these people at heightened risk of identity fraud.
