Health care provider Premera Blue Cross said on Tuesday that the identifying, financial, and medical information for millions of customers could have been revealed in a cyberattack.
In a statement on their website, Premera said that issues related to their network have been resolved and the company is working to strengthen security measures. The initial attack occurred on May 4, 2014, but the intrusion was not discovered until Jan. 29, according to Premera.
The attack potentially affects 11 million customers. About 6 million of those live in Washington state, where some customers are employees at companies like Amazon and Microsoft, Reuters reported.
