The FBI has formally accused the government of North Korea for the hacking of Sony Entertainment Pictures.
Following an investigation, the FBI concluded that there could also have been Chinese involvement in the cyber attack.
In a statement released on Friday, the FBI said that analysis of the malware data used showed links to other malware the FBI knows has has been developed by North Korea. The FBI also said some of the IP addresses which were used to hack Sony were the same as ones used in previous cyber attack attempts on computer networks in South Korea and the US.
Whilst it was claimed the American authorities had been accusing North Korea privately for the Sony hack for some time, this is the first time the rogue state is being officially blamed.
It is also the first time that possible Chinese involvement has been officially made public.
While the FBI believes the attack was carried out by North Korea, it is suspected that it may have been done so with the help of the China in some capacity, either by using Chinese hackers, or using Chinese servers in order to hide the origin of the attack.
However, security experts have claimed that it is unlikely North Korea is behind the Sony hack.
Despite not revealing too many details on the attack, in its statement released earlier, the FBI claims that some of the code used in the cyber attack was written on computer with Korean language and locale.
However, that probably makes it even less likely there was North Korean involvement as the traditional Korean language is actually banned in the North Korea, according to Marc Rogers, an analyst with online security firm Cloudflare.
Also, the location of any computer can easily be changed before the code was distributed, Rogers wrote.
It remains to be seen how the US will respond to the attack and take action against North Korea.
Currently the US has strict trade sanctions in place against North Korea, and a military response is unlikely.
Even if the FBI was able to identify the individual hackers involved, it is unlikely they would ever see the light of day in a US courtroom.
If the US was then to try and launch its own counter-attack against North Korea, whilst this may have some short term success, it is likely to only add further fuel to the fire and could also encourage Pyongyang to launch more attacks on other targets in the US.
