DALLAS-- Personal information for millions of people is at risk after hackers targeted a hospital network.

Community HealthSystems announced the breach onMonday. The organization operates 206 hospitals in 29 states across the country.

It says hackers in China have stolen data on 4.5 million patients.

The breach happened inApril and June of this year, when the hackers accessed patients' names, social security numbers, addresses and phone numbers.

Most patients who received treatment from a network-owned hospital in the last five years could be affected. People who were referred there by a doctor are also impacted.

The large data breach puts these people at a heightened risk of identity fraud.

Community HealthSystems owns the following North Texas hospitals:

  • Dallas Regional Medical Center Mesquite
  • Weatherford Regional Medical Center
  • Lake Granbury Medical Center
  • Hill Regional Hospital Hillsboro
  • Navarro Regional Hospital - Corsicana

Dallas Regional Medical Center issued a statement Tuesday afternoon saying no patient data from their physician practices and clinics affiliated with the hospital in the last five years were part of the breach.

'Our organization believes the intruder was a foreign-based group out of China that was likely looking for intellectual property,' said Dallas Regional Medical Center CEO Tina Pollock in a statement. '[...] The intruder has been eradicated and applications have been deployed to protect against future attacks.'
