The FBI has confirmed North Korea was behind the cyber attacks on Sony Pictures.
“As a result of our investigation, and in close collaboration with other US Government departments and agencies, the FBI now has enough information to conclude that the North Korean government is responsible for these actions,” a FBI statement said.
“While the need to protect sensitive sources and methods precludes us from sharing all of this information, our conclusion is based, in part, on similarities in specific lines of code, encryption algorithms, data deletion methods, and compromised networks.”
“We are deeply concerned about the destructive nature of this attack on a private sector entity and the ordinary citizens who worked there,” the FBI said in the brief statement.
“Further, North Korea’s attack on SPE (Sony Pictures Entertainment) reaffirms that cyber threats pose one of the gravest national security dangers to the United States.”
The FBI said that it had “determined that the intrusion into SPE’s network consisted of the deployment of destructive malware and the theft of proprietary information as well as employees’ personally identifiable information and confidential communications.”
“The attacks also rendered thousands of SPE’s computers inoperable, forced SPE to take its entire computer network offline, and significantly disrupted the company’s business operations.”
While it has seen a rising number of cyber breaches, “the destructive nature of this attack, coupled with its coercive nature, sets it apart,” the FBI said.
