EyeMed email hack exposes 484K Aetna members' data Print An Aetna affiliate on Thursday alerted the federal government that a data breach compromised hundreds of thousands of members' health data. The data breach stemmed from a hacking incident at EyeMed, a company that Aetna contracts with to provide services for members of in its vision benefit plans, a spokesperson from CVS Health, which owns Aetna, said in an emailed statement. In July, a hacker accessed an EyeMed email account and sent phishing emails to contacts in the account's address book, according to a notice EyeMed posted on its website. It's unclear whether the hacker viewed or exfiltrated members' health data. The email account contained names, dates of birth, vision insurance identification numbers, health insurance identification numbers, and some Social Security numbers, birth certificates, medical diagnoses, and financial information of current and former members who receive vision benefits through EyeMed, including Aetna customers.
