Looks as if the hackers are not done with Sony, even though the movie studio caved into demands to cancel the release of the James Franco-Seth Rogen comedy 'The Interview.'

Brand-new threats believed to be from the mysterious group emerged Thursday evening (Dec. 18), a studio source tells CNN. An email obtained by the news service applauds the "very wise" decision to cancel the movie, but delivers a new list of demands as well.

"Now we want you never let the movie released, distributed or leaked in any form of, for instance, DVD or piracy," the poorly worded email states. "And we want everything related to the movie, including its trailers, as well as its full version down from any website hosting them immediately."

The hackers then threaten to release more of the company's "private and sensitive data." Sony executives have declined to comment on the latest threats.

Sony has been the target of hackers over the film about an attempted assassination of North Korean leader Kim Jong-un, with the FBI confirming today (Dec. 19) popular speculation that North Korea is behind the series of cyberattacks.

The company pulled 'The Interview' from release on Wednesday (Dec. 17), after possible terror threats against theaters showing the movie. That much-criticized move followed the cancelation of the New York City movie premiere and the release of several embarrassing private emails from high-ranking Sony execs.
