South Korean intelligence officials yesterday blamed their North Korean neighbours for a cyber attack that paralysed the president's website as well as those of the defence ministry, other state agencies, banks, retailers and media companies.
South Korea is one of the world's most wired nations and the attack highlighted what some see as its vulnerability to cyber attacks from the North and others.
The South's Communications Commission said that the websites of the presidential Blue House, defence ministry and national assembly as well as private companies were inundated by heavy traffic generated by malicious software, beginning on Tuesday.
