A South Korean official was cited by the Yonhap news agency as stating intelligence agencies in Seoul had found signs that computer servers for the government's press room may have been compromised by a cyberattack emanating from North Korea.
Government spokesman Yoon Chang-jung said the press office's computer networks were more vulnerable that government systems because they were connected to commercial computer networks. He said, however, there was "some misunderstanding in the course" of delivering warnings, Yonhap adds.
Authorities early this week said a cyberattack on the website for a South Korean newspaper was tied to Pyongyang.
The misstep comes as South Korean President-elect Park Geun-hye starts preparations for taking office in late February. The opposition Democratic United Party said the miscommunication on the cyberattack was "shameful."
North and South Korea remain technically at war.
