LINE Yahoo has revealed that approximately 440,000 items of LINE user information, including information published in November 2023, are suspected to have been leaked. The company says it is taking measures to prevent recurrence, including strengthening information management.
In November of last year, LINE Yahoo, a South Korean IT company called Naver, released information on LINE users, saying that a company it outsourced to had suffered a cyber attack, and that LINE Yahoo's system had also been accessed illegally. The number of suspected leaked information has expanded to approximately 519,000.
