South Korean broadcasters affected by cyber attack

A cyber-attack has disrupted TV networks across South Korea.

National broadcasters KBS, MBC as well as YTN reported the disruption, with their network systems having been crippled by the attacks. 

The BBC reports that staff at the three broadcasters experienced a locked error screen on their computers, which could not be restarted.

Restoration attempts were made throughout the night, with news scripts being written by hand, to prevent further disruption of service.

In KBS alone, around five thousand office computers and parts of the server were affected.

As KBS’s broadcasting and office networks are run separately, security arrangements around the broadcasting network functions completely blocked any access from the outside. It was therefore unaffected by yesterday’s cyber-attack.

MBC restored its internet homepage yesterday afternoon and YTN is still working on its restoration.
