US officials today stood firmly by the FBI's conclusion that North Korea is responsible for the crippling cyber attack on Sony Pictures that ultimately led to the cancellation of The Interview. After North Korea vehemently denied those accusations earlier on Saturday, White House National Security Council spokesperson Mark Stroh said in a statement, "As the FBI made clear, we are confident the North Korean government is responsible for this destructive attack. We stand by this conclusion." He added, "The Government of North Korea has a long history of denying responsibility for destructive and provocative actions."
"We stand by this conclusion."
North Korea's response to the US called the FBI's accusations "groundless slander." The government, through a statement attributed to an unidentified spokesperson from the country's foreign ministry, called for a joint investigation into the hacking. The spokesperson claimed that "we have means to prove that this incident has nothing to do with us."
While Stroh didn't directly address the government's offer to join an investigation, he did say, "If the North Korean government wants to help, they can admit their culpability and compensate Sony for the damages this attack caused."
