North Korean hackers were behind last month’s cyber attack that brought down the network of a South Korean bank, according to prosecutors in Seoul.
Reuters reported the April 12 take down of South Korea’s agricultural banking cooperative Nonghyup’s computer system impacted millions of customers who could not use the bank’s credit cards and ATMs for more than a week.
The attacks were described by prosecutors as “meticulously prepared and executed” by the same group that launched cyber attacks on South Korean government and business websites in 2009 and in March this year. April’s attack was a new type of cyber terrorism that targeted a private firm in an effort to destroy the financial system, which is “the backbone of (the South’s) capitalist society,” Reuters said.
North Korea is also accused of disrupting GPS signals in the South in March, in a possible attempt to disrupt joint military drills by South Korean and U.S. forces.
