Global hackers' group Anonymous on Saturday released the personal information of another 6,216 subscribers of North Korean propaganda website Uriminzokkiri, on top of the 9,001 subscribers it revealed last week.
Out of the total 15,000 subscribers whose information has been leaked, 2,600 are using email addresses with major South Korean portal sites or websites.
The police, prosecutors, and the National Intelligence Service started investigating on Friday based on the information but are struggling to make progress. It is impossible to confiscate the server of Uriminzokkiri as it is based in China, and users can sign up with a false name, so the authorities may face difficulty proving any South Korean laws were violated.
The list of subscribers includes famous politicians such as former President Lee Myung-bak and former chairman of the Liberty Forward Party Lee Hoi-chang, as well as soldiers and policemen. But most are apparently fake.
A police spokesman said, "It will take over a year to identify the members, uncover to their pro-North Korean activities and bring charges against them."
