North Korea’s access to the Internet has been restored after it was disabled for hours, with the outage coming days after the U.S. accused the country of being behind the hack into Sony Corp.’s computers, reports Bloomberg.
The country’s connection, which Bloomberg reports can be “patchy,” was restored after being out for almost 10 hours.
“North Korea, which has four official networks connecting the country to the Internet — all of which route through China — began experiencing intermittent problems [Sunday] and [Monday] went completely dark, according to Doug Madory, director of Internet analysis at Dyn Research in Hanover, New Hampshire,” Bloomberg reports.
“I don’t know that someone is launching a cyber-attack against North Korea, but this isn’t normal for them,” Madory said. He added: “This is not like anything I’ve seen before.”
While the U.S. linked North Korea to the hack, North Korea claimed it didn’t know the identity of the hackers and said that any U.S. punishment related to the attack would lead to retaliation “thousands of times greater,” the piece reports.
North Korea’s four networks connected to the Internet compare with 152,000 networks in the U.S., Dyn Research said. The North Korea outage appeared to be caused by a distributed denial-of-service attack, the story added. Since any hacker could spend a few hundred dollars to carry out the attack on North Korea, it’s unlikely it was done by the U.S., the report says, citing computer security experts.
