Anthem subsidiaries face Missouri lawsuit over data breach
ST. LOUIS (AP) - A Missouri lawsuit seeking class-action status accuses three insurance agencies of failing to safeguard consumer data from hackers who recently breached health insurer Anthem's computer networks.
A lawsuit first filed in February in St. Louis County on behalf of a Richmond, Missouri, woman was amended Tuesday to add three plaintiffs who allege personal data stolen during the breach is responsible for fraudulent tax returns filed in their name.
Hackers in December or January broke into an Anthem database that included names, employment details and Social Security numbers.
The Missouri suit alleges such information of nearly 100 million consumers "is now in the hands of thieves."
Anthem says it has no evidence that the hackers shared or sold any of the data, or that fraud has occurred against its members.
