FRANKLIN, Tenn. • Hospital operator Community Health Systems, which operates Mountain West Medical Center in Tooele, said a cyberattack took information on more than 4 million patients from its computer network earlier this year.
The Franklin, Tenn. company said Monday that no medical or credit card records were taken in the attack, which may have happened in April and June. But Community said the attack did bypass its security systems to take patient names, addresses, birthdates, and phone and Social Security numbers.
The hospital operator said it believes the attack came from a group in China that used sophisticated malware and technology to get the information. Community Health has since removed the malware from its system and finalized "other remediation efforts" to prevent future attacks.
