A former employee angry over being fired may have organized the hacking of Sony Pictures' computer network, a security expert says.
The FBI has blamed the government of North Korea, allegedly as reprisal for the movie The Interview. The movie depicts a talk show host and producer who score an interview with North Korean leader Kim Jong Un and are then recruited by the CIA to assassinate him.
But Kurt Stammberger, a senior vice president with the security firm Norse, told the Security Ledger researchers there believe the hacking was an inside job. Stammberger said the team has even identified one possible perpetrator, a woman who worked for Sony for 10 years before losing her job in a recent reorganization.
The woman has a "very technical background" and has posted angry messages online, Stammberger said. He said a total of at least six people appear to have been involved in the hacking, with the others including two in the United States and others in Canada, Singapore and Thailand.
