North Korea’s Internet Disconnection After Sony Cyberattack: Is USA to Blame?

The Sony cyberattack takes a possibly worse turn that can be alarming. American President Barack Obama declared to have a “proportionate response” to the North Korean attack against Sony. Just two days after the president’s announcement, North Korea lost their internet connection. Suspicions regarding the involvement of the US government were starting to surface.

However, early reports suggested there was no connection between Obama’s promise of retaliation and the disappearance of North Korea from the internet.


Sources said the timing was not coinciding with the suspicions. Arbor Network’s traffic monitoring project, Atlas, tracked the connection problem throughout the week, way before FBI confirmed the involvement of North Korea in the cyberattack and Obama’s declaration. Obama was not even prepared, based on his statement that he was still waiting for options of retaliation.

Technically, North Korea was experiencing “denial-of-service” attack. It works by using illegal traffic to flood a connection or server. Because of that, legitimate traffic is impossible to get through.

North Korea’s connection had only one link to China Unicom, which is the pathway for the country’s limited internet traffic.

According to Atlas, the recent cyberattack to North Korea was slow in progress, suggesting that the attackers had limited capabilities. If Obama ordered the attack, it would have resulted in just seconds, not days. Dan Holden from Atlas assured that the American government was not responsible.

“Much like a real world strike from the U.S., you probably wouldn’t know about it until it was too late. This is not the modus operandi of any government work,” Holden said.

According to The Verge, the content delivery network CloudFlare had a similar statement with Atlas. CloudFlare CEO Matthew Prince stated that there were three alternate reasons: hardware failure, cutoff from China Unicom or voluntary internet shutdown.

Prince believed anyone on the web could be the culprit of the recent North Korea dilemma because of the “exceptionally low barrier to entry.”

There were already anonymous groups claiming the attack such as Lizard Unit.

“I’d be far more surprised if it was a government launching the attack than I would if it was a kid in a Guy Fawkes mask,” Prince told The Verge.
