Los Angeles: The FBI is investigating threatening emails sent to employees of Sony Pictures, which was hit by a disruptive cyberattack last week.
The FBI's statement Friday doesn't provide details.
However, Variety says a group that first hacked Sony on Nov. 24 is taking credit for an email, written in broken English, that demands employees object to “the false of the company.”
“If you don't,” the message warns, “not only you but your family will be in danger.”
Messages to Sony representatives weren't immediately returned.
Cyberattacks have put unreleased movies and personal employee information online.
There has been speculation that the attack was North Korean retaliation for Sony's new movie, “The Interview,” about an attempt to assassinate that country's leader, Kim Jong Un.
On Thursday, North Korea denied involvement.
