Premera Blue Cross, which serves the Pacific Northwest and Alaska, says it was hacked last May — and its customers’ claims and clinical data were exposed.
The breach, which affects 11 million customers, was discovered on January 29 of this year, the company says in a statement. That’s the same day Anthem discovered its data breach, but a Premera Blue Cross spokesperson says it’s not clear whether or not the two are related at this point.
