The breach, which a U.S. official has said is linked to North Korea, resulted in the release of Social Security numbers, financial, medical and other personal info for about 50,000 Sony workers. "In addition to implementing a sophisticated public relations campaign to portray the breach as beyond its control, (Sony) focused its early remediation efforts on controlling the damage associated with salacious comments appearing in emails about movie stars and removing pirated films from the Internet," the suit states. In addition to Social Security numbers, salary details and medical information, hackers posted several Sony films that were unreleased or are still in theaters.
