A hacking attack on an internet provider in South Korea brought down the websites of three national broadcasters and two major banks on Wednesday, prompting the military to raise its alert level over fears of North Korean involvement.
Hacker broke into a network provided by LG UPlus Corp, replacing websites with a page claiming responsibility for a previously unknown group called the “Whois Team”. The message showed three skulls and an ominous warning that the attack marked the beginning of “Our Movement”. The websites of national television networks KBS, YTN and MBC were caught up in the attack, as well the the Nonghyup and Shinhan banks.
South Korea’s military raised its state of readiness in response to the attack. In the past North Korea, which recently scrapped an armistice with the South and threatened a return to war, has launched cyber attacks against its neighbour. These include a 10 day denial of services attack which experts suggest was designed to test South Korea’s defences. Police have refused to comment on the possibility of North Korean involvement in Wednesday’s attack, saying that it will take days to collect evidence from such a massive incident. Teams of investigators have been sent to all affected sites, said a police spokesman.
