South Korean Broadcasters Hit by Cyberattacks
North Korea is believed to be the perpetrator, after the country made aggressive threats of imminent "countermeasures" following its own computer outages five days ago.
South Korean authorities are investigating a possible cyberoffensive by North Korea, after leading media companies and banks reported that their computer systems had been attacked early Wednesday.
Prominent South Korean broadcast stations KBS and MBC reported that hundreds of its computers were paralyzed, according to a New York Times report. Cable channel YTN reported similar outages.
Four South Korean banks reported simultaneous attacks on their computer systems as well. Shinhan Bank, NongHyup, Jeju and Woori all claimed various levels of intrusion and damage to their networks. NongHyup and Jeju said computers at their various branches were frozen after they were “affected with viruses and their files erased,” the Times reported.
Police in South Korea have not yet established a direct link between the widespread computer attacks and North Korea. But given that the offensive comes just five days after North Korea publicly blamed South Korea and the United States for cyber attacks that crippled computers in Pyongyang last week, all suspicions have been directed northward.
Tensions between North and South Korea have been especially high since the North issued a barrage of belligerent threats toward the U.S. and South Korea -- including claims of a possible preemptive nuclear strike -- in the wake of U.N. imposed new sanctions against North Korea over its Feb. 12 nuclear test.
