Several government and private sites fall victim to hackers, according to South Korea's science ministry.
South Korea has suffered its latest cyberattack, and one that marked the 63rd anniversary of the start of the Korean War.
The country's science ministry said that multiple government and private sites were hit in Tuesday's hacking, the Associated Press has reported. Included in the attack were the site for the country's presidential Blue House and several media servers.
The South Korean government said that it's investigating further and has urged officials and citizens to secure their computer systems, the AP added.
No potential suspects were named in the attack. But North Korea would likely top the list. In April, South Korea accused its neighbor to the north of launching a March cyberattack that affected tens of thousands of computers at banks and broadcasting stations.
A spokesman for South Korea's Internet agency told the AP at the time that the attack mimicked past attempts by North Korea to hack into key Web sites. The spokesman singled out an espionage agency run by the North Korean military.
