Former Sony employee might have been behind the Sony cyber attack. After investigations, a security firm informed the FBI that the hacker of Sony might have been an ex Sony worker together with a team of cyber experts. A week ago the Federal Bureau Of Investigation declared that North Korea was the brain of the operation.
Kurt Stammberger, senior vice president for market development at cyber intelligence firm Norse, declared that they gave the FBI “raw data” and had a three hours meeting with them on Monday in St. Louis. He also stated, that the FBI seamed very open to receiving their information.
The firm has evidence about malware samples that only a person inside Sony could posses. So far the evidence claimed by the FBI accusing North Korea of the attack, have been described inconclusive. And there were a lot of sceptics questioning wether or not, North Korea, had the technical ability to hack Sony’s systems. The theory that it might have been carried out by former Sony employees seams more plausible. Even so, Tuesday, the FBI stood firm on its previous announcement.
“(…) Government of North Korea is responsible for the theft and destruction of data on the network of Sony (…). “There is no credible information to indicate that any other individual is responsible for this cyber incident.” said the FBI in a statement.
Dmitri Alperovitch, working for the security firm CrowdStrike, said that the United States has a lot more evidence proving North Korea’s involvement in the cyberattack, but the government is not ready to release it yet.
An online post on the blog of Norse, said that their investigation surrounds around a group of at least six people, who may have been sabotaging Sony’s network. They seam to be sure that one of them used to work for Sony, and was aware of the technical system and had inside information.
They believe the rest of the hackers are international, belonging to different countries. They might have joined forces against Sony’s policy as the company let go a lot of people, earlier this year. Investigators think one of them is an American and others are from Canada, Thailand and Singapore.
The cyber experts said that they are not doubting FBI’s abilities and evidence, but their investigation hasn’t come across anything that linked the attack to another nation.
