The Sony Pictures hack is thought to be one of the most serious by volume of data stolen already.
Now, there’s evidence that whoever hacked Sony also made off with the social security numbers of thousands of employees — including some of the actors and celebrities who worked with the film studio.
The Wall Street Journal reports the compromised documents included SSNs for Sylvester Stallone, Judd Apatow and Rebel Wilson, among others.
Much of the data was reportedly stored in spreadsheet files without any sort of password protection. Passwords were apparently in a file named “passwords.”
The leading theory among infosec experts is North Korea was behind the breach.
The country isn’t happy with one of Sony’s upcoming movies in particular. "The Interview" tells the story of an assassination attempt on Kim Jong Un.
“It’s very clear that a nation-state has done it. And it’s very clear that Sony might have to change its behavior because a nation-state does not find it acceptable,” said Dave Aitel of Immunity, Inc.
It’s not clear if North Korea — or whoever has Sony’s data now — has any specific interest in celebrity social security numbers. The Wall Street Journal says representatives for those actors affected have declined to comment.
