Affected Kodiak residents received mailings Monday from Health insurance company Premera Blue Cross, informing them that the FBI is helping investigate a “sophisticated cyberattack” that may have captured their personal information, including bank account information and Social Security numbers.
The attack that took place on Jan. 29 may have affected 11 million people, the company said in a statement.
The Washington-based company serves millions of customers across Washington, Oregon, Alaska and other states.
“We at Premera take this issue seriously and regret the concern it may cause,” said Premera President and CEO Jeffrey Roe. “I’m writing to provide you information on the steps we are taking to protect you and your information moving forward.
The company said the initial attack occurred on May 5, 2014 and it worked closely with Mandiant, a cybersecurity firm, to remove the infection created by the attack in the company’s information technology systems.
The attackers captured personal information of members, including names, dates of birth, email and postal addresses, phone numbers, Society Security numbers and bank account information.
“We also have no evidence to date that such data has been used inappropriately,” the company said.
Roe said the company is providing clients free, two-year membership in Experian’s free credit monitoring and identity protection services.
The Premera security breach occurred at almost the same date that Anthem, another Blue Cross company, told the FBI that it has also been the target of a cyberattack.
