Even if it was behind the attacks, spotting North Korean Internet traffic can be a tricky business.
While the country has its own block of IP (Internet Protocol) addresses, none of them are apparently in use and the few North Korean Web sites that exist on the Internet are almost all located in China or Japan.
Instead, connectivity for the country comes via connections to Chinese providers and that would make the traffic appear as Chinese. It would only be with more careful analysis of the individual addresses in use that it might be possible to suspect North Korean data.
To date there's no hard evidence of where the attacks came from, so no party can be ruled out. The governments of other nations, which are almost certainly all involved in the same, murky world of cyberespionage, do their best to hide their tracks, so why wouldn't North Korea do the same?
The true origin of the week's attacks is likely never to be known, but one thing's for sure: As the world comes to rely more and more on the Internet and computers, they won't be the last.
