SEOUL, March 25 (Yonhap) -- Some of the malicious code that paralyzed network systems at major South Korean banks and TV broadcasters last week originated from the United States and three European countries, police here said Monday.
Local TV broadcasters KBS, MBC and YTN along with Shinhan, NongHyup and Jeju banks suffered a massive network failure on Wednesday that halted financial services and crippled operations.
