South Korea Intensifies Crackdown on Illegal Online Gambling

South Korean authorities have intensified their nationwide crackdown on illegal online gambling, detaining 5,196 people over the past year as part of a coordinated enforcement drive. The campaign, led by the National Office of Investigation (NOI) under the Korean National Police Agency, ran from November 2024 to October 2025 and targeted both domestic bettors and offshore operators supplying unlawful gaming services.

A notable trend emerged in the data: young adults made up a significant share of those caught. Individuals in their 20s and 30s each represented roughly a quarter of those apprehended, together accounting for more than half of all arrests. Authorities placed 314 suspects in formal detention, and seized an estimated KRW123.5 billion (US$83.6 million) in illicit gambling proceeds.

The operation also extended far beyond South Korea’s borders, disrupting large-scale online gambling rings run from overseas. Investigators identified 97 suspects linked to offshore networks handling approximately KRW530 billion (US$358.8 million) in gambling activity, with operations traced to China, Cambodia, Vietnam and the Philippines. One of the most significant enforcement actions involved the arrest of 23 members of a group operating a Philippines-based gambling platform.

The Korean National Police Agency affirmed that the crackdown will continue through October 2026 as the country aims to curb the rise in illegal digital gambling and dismantle cross-border cybercrime ecosystems. With online gambling becoming more accessible due to rapid technological growth, authorities say the long-running initiative highlights the government’s determination to strengthen enforcement, enhance international cooperation, and protect citizens from the harms associated with unregulated gaming.
