South Korea Dismantles $17.2 Billion Illegal Gambling Network That Produced Casino Sites in 10 Minutes

South Korean police have dismantled one of the largest illegal online gambling networks uncovered in the country, which handled $17.2 billion in wagers across 188 casino websites.

The Chungnam Provincial Police Agency said Monday (Oct.19) that it apprehended 77 people, including website suppliers, operators, and gamblers. 21 have been detained. The suspects built and distributed the sites between March 2023 and July 2026 from offices in South Korea, Vietnam, and Cambodia.

Rapid Development Operation

The network recruited software developers from major South Korean corporations. They created an in-house program that produced a casino website in around 10 minutes. The group contracted with legitimate overseas gaming companies for video feeds and virtual gaming credits, then packaged them for smaller operators.

Those operators were charged a maintenance fee of 3 million won (about $2,250) per site each month. They recruited customers through adult-only internet cafés. Police estimate total wagers at 23 trillion won (about $17.2 billion). Criminal proceeds for the two main supply groups reached 150 billion won (approximately $112 million), with casino-feed suppliers taking 120 billion won and website developers 30 billion won.

Investigation Scale and Enforcement Steps

The case began in November 2025 with arrests of lower-level operators, then traced 795 bank accounts and overseas messages. Suspects shifted offices between South Korea and Southeast Asia while using foreign servers. Of those apprehended, 25 linked to supply, 33 to operations, and 19 were gamblers. Organized crime charges were filed against 24 in the development side.

All 188 sites were shut down, 408 web addresses blocked, and 9.6 billion won (about $7.2 million) frozen in proceeds. Authorities are seeking Interpol red notices for 12 suspects who fled overseas. This enforcement action, as first reported by Casino.org News, represents South Korea’s largest gambling bust.
