(Seattle, WA)  --  Seattle-based attorneys are involved in the fallout from a data breach that recently hit Sony Pictures in Hollywood.  The firm Keller Rohrback has filed a federal lawsuit against the movie studio, claiming Sony is liable for the data breach that resulted in the personal information of thousands of employees and their families being posted on the Internet.  Law firm partner Gretchen Cappio told KIRO-TV that Sony was aware its computer security system was vulnerable because of a previous data breach.  U.S. officials say North Korea is behind the latest data breach.
