The group that hacked Sony Pictures leaked another batch of data Tuesday, this time accompanied by an ominous message that overtly threatens violence for the first time.

Posted on the anonymous Pastebin website, the message foresees a "bitter fate" for those who choose to see Sony's upcoming movie, The Interview, in cinemas. It also says that "the world will be full of fear" and references 9/11.

Though the language is ominous, a Department of Homeland Security official told Mashable that there is "no credible intelligence" showing a plot to attack United States movie theaters at this time.

The full text of the message, in the hackers' usual jumbled English, is as follows:

Warning We will clearly show it to you at the very time and places “The Interview” be shown, including the premiere, how bitter fate those who seek fun in terror should be doomed to. Soon all the world will see what an awful movie Sony Pictures Entertainment has made. The world will be full of fear. Remember the 11th of September 2001. We recommend you to keep yourself distant from the places at that time. (If your house is nearby, you’d better leave.) Whatever comes in the coming days is called by the greed of Sony Pictures Entertainment. All the world will denounce the SONY.

Along with the message, the hackers released data that they labeled as "Christmas gift: Michael Lynton," presumably meaning that it includes files belonging to the Sony Entertainment CEO. Mashable was still reviewing the data.

The hackers, who go by "Guardians of Peace," stole a massive amount of corporate data from Sony Pictures in late November, and have been slowly releasing it ever since. They previously released years' worth of correspondence from the inbox of Amy Pascal, the studio's co-chairman.

The Interview, a comedy that portrays James Franco and Seth Rogen as assassins of North Korean leader Kim Jong-un, opens nationwide on Christmas. The movie has raised the ire of the North Korean government, leading to speculation that Kim's deputies or sympathizers are behind the Sony hacking.

But some security experts say the hackers may have nothing to do with North Korea and are using the movie as a cover for whatever their true motive may be.

In addition, the hackers sent an email to Sony executives three days before the original cyberattack in November, demanding "monetary compensation" to avoid the hack and making no reference to the film that they now claim to find offensive.
