SEOUL, South Korea (AP) — Police and South Korean officials were investigating the simultaneous shutdown Wednesday of computer networks at several major broadcasters and banks. While the cause wasn't immediately clear, speculation centered on a possible North Korean cyberattack.
The shutdown came days after North Korea blamed South Korea and the United States for cyberattacks that temporarily shut down websites in Pyongyang.
Officials at the two South Korean public broadcasters KBS and MBC said that all computers at their companies shut down at 2 p.m. (0500 GMT). The officials said the shutdown was not immediately causing any damage to their daily TV broadcasts.
