The ongoing hacking nightmare that Sony Pictures has been suffering for over a week now seemingly has gotten very personal. An email allegedly from the Guardians of Peace hackers showed up in the inboxes of a number of Sony employees this afternoon threatening them, their families, and saying the company will “collapse.” It also implied the action was an inside job, adding in broken English that “one beside you can be our member.”

“Please sign your name to object the false of the company at the email address below if you don’t want to suffer damage. If you don’t, not only you but your family will be in danger,” the correspondence said (see the full email below). “This is getting very creepy,” said a source who received the email today. “We thought the worst was over.”

If Sony corporate thought the worst was over, they reacted fast Friday to the email.

“We understand that some of our employees have received an email claiming to be from GOP,” said a Sony spokesperson. “We are aware of the situation and are working with law enforcement.”

Sony had already been working with the FBI over the hacking that shut down the company’s computer system, revealed executive, employee and talent info and apparently leaked online five films including the still-in-theaters Fury and the yet-to-be-released Annie. In an email to staff Tuesday, Sony bosses Michael Lynton and Amy Pascal, who had details of their financial arrangements with the company made public, called the hacking ““malicious criminal acts.”

Here is the email Sony employees received today:
