The financial and medical records of 11 million Premera Blue Cross customers may have been compromised due to a network breach on the health care provider's systems. Information about the attack, which took place on 5 May, 2014 but was not discovered until January this year, can be followed via premeraupdate.com—a website created to inform customers about the compromise.
Working with security firm, Mandiant and the FBI to investigate the attack, many signs point to a state-sponsored attack originating in China, though that outcome has yet to be confirmed.“Individuals who do business with us and provided us with their email address, personal bank account number or social security number are also affected,” the company said in a press statement. “The investigation has not determined that any such data was removed from our systems. We also have no evidence to date that such data has been used inappropriately.”
Premera customers are being notified of the situation via postal mail letters, will be given two years of free credit monitoring.
“Cyber-crime remains a significant threat and the FBI will continue to devote substantial resources and efforts to bringing cyber criminals to justice,” the FBI told the media in an emailed statement.
