Seoul: SK Chairman Chey Tae-won on Wednesday made a public apology for a recent large-scale data breach at SK Telecom Co., which may have leaked sensitive information of some 25 million users. "I apologize for the concerns and inconvenience caused by a cyberattack at SK Telecom," Chey said during a press conference.
According to Yonhap News Agency, SK Telecom detected hacking on April 18 that showed signs of a large-scale leak of customer universal subscriber identity module (USIM) data. In response, the company has offered to replace the USIM of all 25 million subscribers, including 2 million budget phone users, free of charge to prevent potential damage.
