Social game developer Zynga Inc., the company behind popular mobile games including Words with Friends, has been hit with a class action lawsuit stemming from a data breach that reportedly resulted in hundreds of millions of user accounts being hacked. 

Lawyers at Cotchett, Pitre & McCarthy; Foulston Siefkin; and The Miller Law Firm filed suit Tuesday in the U.S. District Court for the Northern District of California on behalf of a nationwide class of Zynga account holders whose personally identifiable information was stolen in the breach disclosed on the company’s website in September.
