The litigation continues: Sony Pictures Entertainment now faces yet another class action lawsuit from ex-employees alleging that the studio failed to take adequate precautions to protect private information.

The lawsuit filed in federal court in Los Angeles on Thursday is similar to three others filed earlier this week. It alleges negligence on the part of SPE and violations of privacy laws.

SPE, which “engages in the entertainment industry as part of a vast multinational corporate conglomerate, knows or should know that it may be the target of the world’s most sophisticated data hackers or cybercriminals,” and it failed to take “adequate steps” to protect itself from the possibility of an attack, says the suit filed by Michael Levine, former technical director for Sony Pictures Imageworks from 2003 to 2012, and Lionel Felix, a former director of technology who ran IT infrastructure for Sony Pictures Digital Entertainment from 2001 to 2004.

The plaintiffs were represented by Michael Sobol and RoseMarie Maliekel of Lieff Cabraser Heimann & Bernstein.
