    North Korea is believed to be behind the recent data leaks from South Korea's nuclear power plants, investigators said Tuesday.

    Late last year, an unidentified hacker posted blueprints of nuclear power plants and threatened to destroy the facilities while demanding they be shut down.

    Last week, the hacker posted more files on Twitter with documents concerning the country's advanced power reactor 1400, while demanding money, Yonhap news agency reported.

    Announcing the results of their preliminary probe into the case, investigators said the series of incidents "is believed to have been caused by an (unidentified) group of North Korean hackers who "aimed at causing social unrest and agitating the people."

    The investigators said the hackers stole the data through hacking e-mails and online communities used by former and current officials of the Korea Hydro and Nuclear Power Co., instead of directly infiltrating the operator's network.

    "We've learned that the malicious code used in the e-mail attack in December was similar to what North Korean hackers usually employ," an official of the investigation team said.

    "Multiple Internet protocol addresses used for the attacks were found to be based in North Korea," he added.
