Community Health Systems Professional Services Corporation (CHSPSC) confirmed an external cyber attack on its network between April and June 2014, discovered in July 2014. The attacker, believed to be a Chinese Advanced Persistent Threat group, bypassed security measures and exfiltrated data including names, addresses, birthdates, Social Security numbers, phone numbers, and employer/guarantor names. No credit card or medical/clinical information was taken. CHSPSC engaged forensic experts and federal law enforcement, contained the breach, and offered one year of identity theft protection via Kroll.
