LEE COUNTY, Fla.- WINK News is getting new details into a major cyber attack that stole patient records from a hospital system with locations here in Southwest Florida.

Community Health Systems is based out of Tennessee, but has five hospitals in Collier, Lee and Charlotte counties.

CHS says a cyber attack took information on more than four million patients nationwide. The attack is believed to have happened in April and June, but we're just now getting new details. CHS says no medical or credit records were taken in the attack, but patient names, addresses, birthdates and phone and social security numbers were compromised.

The information came from patients who were referred to or received care from doctors tied to the company over the past five years.

CHS is notifying patients who've been affected and offering them identity theft protection.

CHS operates Physicians Regional in Collier, Lehigh Regional Medical Center in Lee, and Bayfront Health Centers in Charlotte County.    

WINK News reached out to our local hospitals and got the same statement from each one. It doesn't say exactly how many people here may have been exposed, although some were indeed exposed. And hospital officials believe the attack was the work of a sophisticated group of out China. It also says new security measures are in place to prevent this from happening again.
