Sony Pictures released a movie called The Interview, a comedy about a fictional assassination of North Korean leader, Kim Jong Un.. North Korean didn't find it funny and hacked into Sony's computers, rendering thousands of computers inoperable and forced Sony to take its entire computer network offline. That wasn't enough, they then threatened terror attack on US citizens if Sony doesn't cancel showing the movie, forcing Sony to pull the interview from theaters and losing almost $200m. Then the US govt got involved and told Sony to go ahead and release the movie, that they don't take lightly to threats and promised to retaliate for the attack on Sony. It looks like they've kept their to promise. North Korea is currently offline. Lol
"Internet connectivity between North Korea and the outside world is currently suffering one of its worst outages in recent memory, suggesting that the country may be enduring a mass cyber attack a few days after President Obama warned the US would launch a "proportional response" to North Korea's hack against Sony
North Korea, which has four official networks connecting the country to the Internet -- all of which route through China -- began experiencing intermittent problems yesterday and today went completely black, according to Doug Madory, director of Internet analysis at Dyn Research in Hanover, New Hampshire."
