Sorry - this page has been removed. US tapped N Korean networks years ago, providing proof of Sony hack – reports
(4 months later)
This could be because it launched early, our rights have expired, there was a legal issue, or for another reason. The US National Security Agency began tapping into North Korean computer networks in 2010, an effort that ultimately helped provide evidence that Pyongyang was behind the cyber attack on Sony Pictures, the New York Times reported on Sunday.
Citing former US and foreign officials and an NSA document, the Times said the spy agency was able to penetrate North Korean systems with the help of South Korea and other allies after first tapping into Chinese networks that connect North Korea to the rest of the world.
For further information, please contact: The newspaper quoted officials as saying the program grew into an effort to place malware that could track many networks and computers used by hackers in North Korea.
Such activity proved crucial in persuading President Barack Obama to implicate the North Koreans in the Sony attack, the officials told the paper.
It was the first time the US directly accused another country of a cyber-attack of such magnitude on American soil.
Obama “had no doubt” in this case, a senior US military official told the Times.
North Korea has described the accusation as “groundless slander”.
Sony’s network was crippled by hackers in November as the company prepared to release The Interview, a comedy about a fictional plot to assassinate North Korean leader Kim Jong-un. The attack was followed by online leaks of unreleased movies and emails that caused embarrassment to executives and Hollywood personalities.
US officials could not immediately be reached for comment.
