Hackers attacked Korea's No. 3 Internet portal Nate and blogging site Cyworld on Tuesday to access the personal information of 35 million users in what could be the country's biggest-ever cyber attack.
SK Communications, which operates the websites, said on Thursday that the hackers targeted Web surfers' personal information, including their names, phone numbers, e-mail addresses, IDs, passwords and resident registration numbers.
Authorities believe the stolen information may be used for voice phishing or sending spam messages. But SK Communications said passwords and resident registration numbers had been encrypted to make it difficult for hackers to decipher them.
