South Korea accuses North of cyber attacks


SEOUL (Reuters) - South Korea accused North Korea on Tuesday of mounting cyber attacks on the websites of its presidential office and other government agencies, saying it had identified signature malicious computer codes and an internet address.

The cyber attacks took place last month, on the anniversary of the beginning of the 1950-53 Korean War which left the peninsula divided between the rival countries.

North Korea has been suspected of masterminding previous cyber attacks on South Korea, including one in March that paralyzed tens of thousands of computers and servers at major broadcasters and banks.

North Korea has repeatedly denied responsibility for such attacks saying it has also been a victim of hacking.



The malicious computer codes and technique of the attack were similar to those detected in previous hacking attacks traced to the North, officials added.

The accusation comes as the two Koreas wrangle over the reopening of a joint factory park just inside North Korea that North Korea closed during a period of tension that began when it conducted its third nuclear test in February.

They failed to reach agreement on Monday on the reopening of the complex.


South Korea's defense minister said at a recent conference that North Korea had about 3,000 highly trained cyber warfare personnel, according to media reports.

In March, the North suggested the United States was behind cyber attacks on its internet servers after reports of disruptions to its main news services.

A hacker collective known as Anonymous said it had attacked North Korean websites on the anniversary of the Korean War.

The group denied through Twitter posts any involvement in attacks on South Korea.
