UPDATE, 3:00 p.m. PST:

A second lawsuit was filed against Sony on Tuesday, this time by a group of production managers, according to The Hollywood Reporter.

Plaintiffs include Susan Dukow and Yvonne Yaconelli, who claim Sony should have known better than to provoke North Korea by including the real Kim Jong-Un in The Interview.

Unlike the earlier lawsuit (see below) which was filed in federal court, Dukow and Yaconelli filed in Los Angeles Superior Court. But like the federal case, it also points the finger at lax cybersecurity in the face of threats and known weaknesses and is seeking unspecified damages.

EARLIER:

LOS ANGELES — A class-action lawsuit against Sony Pictures Entertainment over its devastating data breach hit the federal courts Tuesday morning, the proverbial first drops in what will inevitably be a deluge of legal action against the studio.

Two former employees, Michael Corona and Christina Mathis, filed the action in U.S. District Court. As it goes with class-action suits, the filing invites "others similarly situated" to join. They are seeking unspecified damages and a jury trial.

Calling the hack "an epic nightmare, much better suited to a cinematic thriller than to real life," the lawsuit says the breach "boils down to two inexcusable problems: (1) Sony failed to secure its computer systems ... despite weaknesses that it has known about for years, because Sony made a “business decision to accept the risk”of losses associated with being hacked; and (2) Sony subsequently failed to timely protect confidential information of its current and former employees from law-breaking hackers" who warned Sony about what they were planning.

Corona, who now lives in Virginia, is a former Sony Pictures Entertainment employee who claims his personal information, including his Social Security number, were leaked in the breach, causing him to spend $700 on identity theft protection for the year. Mathis, who lives in California, is a former employee of subsidiary Sony Pictures Consumer Products who hasn't worked for the company in 12 years but claims she still had her Social Security number and address leaked.

Sony Entertainment CEO and chairman Michael Lynton held an all-hands meeting on Monday, telling gathered employees that the hack "won't take us down. You should not be worried about the future of this studio." The plaintiffs said they had not been contacted by the studio.

The lawsuit cites multiple reports suggesting Sony lost control of its cryptographic keys, which would enable a hacker to prowl its servers undetected, as far back as a year ago. The detail is significant because the 2011 data breaches to Sony's PlayStation network also came via stolen cryptographic keys, yet "Sony's bad information technology security habits continued."

They are suing for negligence, violation of state medical confidentiality laws and civil codes,

Sony did not immediately respond to a Mashable request for comment on the lawsuit.
