Hackers in China have stolen secrets on South Korea's defence and foreign affairs by using bogus emails claiming to come from Seoul officials and diplomats.
The National Intelligence Service uncovered the hacking early this year and warned government offices about the danger of such emails.
Hackers sent emails in the names of South Korean diplomats, presidential aides and other people familiar to Seoul Officials.
Attached files containing viruses were disguised as important documents, such as analyses on North Korea's economy.
When a recipient clicked on the attachment, the virus started downloading documents in his or her computer
