South Korean Supreme Court Affirms Privacy Law Liability for Illegal Gambling Operators Using Stolen Data

South Korea’s Supreme Court has established that operators of unlawful online gambling platforms can be held criminally responsible for violations of data protection laws when they acquire and use personal information obtained through illegal means. The ruling clarifies that individuals involved in illicit gambling operations are not exempt from liability under privacy legislation simply because the information was used within the context of an illegal enterprise.

The decision was issued by the Supreme Court’s First Division, which rejected an appeal filed by an unnamed defendant who sought to overturn a lower court judgment that found him guilty of breaching the Personal Information Protection Act. The man had already been convicted of operating an unauthorized online gambling platform and pursued his appeal after unsuccessfully challenging the verdict in the appellate courts.

According to reports from the South Korean media outlet News1, the district court sentenced the defendant to one year in prison for his offenses. In affirming the conviction, Supreme Court Justice Seo Kyung-hwan emphasized that businesses or individuals who obtain or utilize personal data that was originally acquired through unlawful hacking activities must also be regarded as “personal information processors” under applicable legal standards.

During the proceedings, prosecutors explained that the defendant established an online gambling platform in 2024 with the assistance of an accomplice. Authorities alleged that, in preparation for launching the operation, the pair acquired customer information that had been unlawfully obtained from another gambling website operator whose identity remains unknown.

The data set allegedly contained sensitive personal details belonging to 796 users of the other platform, including full names, bank account information, and mobile telephone numbers. Prosecutors argued that the defendant subsequently used the stolen information while conducting operational tests on his own gambling website. These tests reportedly included simulations and evaluations of account deposits, withdrawal functions, and the performance of various gaming systems available on the platform.

The defendant maintained that his actions did not constitute a criminal offense because the website was never officially launched to the public. He argued that the use of the data occurred only during testing and that no actual gambling service was ultimately provided to users.

However, both the High Court and the Supreme Court rejected this defense. The higher courts concluded that the defendant’s argument was unsupported by the facts and declined to accept the claim that “no crime took place, because [his] site never went live.”

Judges reviewing the case determined that the platform’s financial systems were fully operational when law enforcement authorities intervened. Evidence presented during the proceedings showed that deposit and withdrawal functions were functioning at the time of the defendant’s arrest, contradicting his assertion that the website remained inactive.

The Supreme Court likewise dismissed his broader argument that the platform had never become accessible to the public. Prosecutors informed the court that users were in fact able to “access the site and play games such as baccarat and slots.” Authorities also submitted evidence demonstrating that “functions for depositing and withdrawing gambling funds were actually operating” when the arrest took place.

The ruling comes amid heightened concern over illegal gambling activities across South Korea. Gambling-related offenses have remained a major topic of public discussion throughout the year, with law enforcement agencies warning that both gambling addiction rates and gambling-related criminal activity among young people have been increasing.

The issue has also drawn attention within South Korea’s political, entertainment, and sporting communities. Several public figures, including athletes, politicians, and celebrities, have faced scrutiny over alleged involvement in gambling activities. In a recent example, four prominent professional baseball players returned to competition after serving lengthy suspensions related to gambling activities conducted in Taiwan.

South Korea maintains some of the strictest gambling regulations in the region. Under current law, most forms of online gambling are prohibited, and South Korean citizens are also barred from participating in gambling activities at overseas land-based casinos. The Supreme Court’s latest decision reinforces the government’s broader efforts to combat illegal gambling operations while simultaneously strengthening the enforcement of personal data protection laws.
