Gov't confirms Pyongyang link in March cyber attacks

Amid escalating tension on the Korean Peninsula, the South Korean government on Wednesday announced that North Korea was behind the massive hacking attack that paralyzed networks of local financial firms and broadcasters last month.

Three South Korean banks -- Shinhan, NongHyup and Jeju -- and their insurance affiliates as well as three TV broadcasters -- KBS, MBC and YTN -- were hit by the cyber attack as malicious code infected some 48,000 computers in their networks on March 20.

Following the initial attack, 58 YTN affiliate servers and 14 anti-Pyongyang Web sites, including those operated by North Korean defectors, also suffered another round of attacks on March 25 and 26.
