Anthem has updated its estimate of how many customers’ records were compromised in the data breach. The original estimate of 80 million has been sharpened to 78.8 million. The company announced that from 8 million to 18 million of those individuals are not customers of Anthem. Anthem is part of a national network of “independently run” Blue Cross Blue Shield plans through which BCBS customers can receive medical services when they are in an area where BCBS is operated by a different company, Reuters reports.”]
