Computer networks of broadcasters, banks paralyzed

Computer networks of the nation's key broadcasters and banks were completely paralyzed Wednesday in what appeared to be a cyber attack, police said.   

At least three broadcasters -- KBS, MBC and YTN -- and two banks -- Shinhan Bank and Nonghyup -- reported to the National Police Agency (NPA) that their computer networks were entirely halted around 2 p.m. for unknown reasons, police said.   "Reports have been made simultaneously so we have dispatched investigators to the scene," a police officer handling cyber-terrorism at the NPA said, adding that officers will review all possibilities, including a cyber attack.   The presidential office Cheong Wa Dae is looking into the possibility of North Korea's involvement in the simultaneous network crash of the local broadcasters and banks, an official at the office said.   "The computer network has been paralyzed since 2 p.m. and we cannot do any business," an official of public broadcaster KBS said.   Another official of cable broadcaster YTN said not only the computer network but also editing equipment for the broadcasting system has also been paralyzed.   "We are figuring out the exact cause and it is expected to affect the broadcast," the official added.
