Working with a computer security company, it determined the attack was carried out by a group based in China that used 'highly sophisticated malware' to attack its systems. The hackers got away with patient names, addresses, birthdates, telephone numbers and Social Security numbers of the 4.5 million people who were referred to or received services from doctors affiliated with the company in the last five years. The stolen data did not include patient credit card, medical, or clinical information.
