South Korean Police Bust Supplier Network Behind 188 Illegal Gambling Sites and KRW23 Trillion in Bets

Police in South Chungcheong say they have dismantled the top of a pyramid that bought live casino feeds and game credits from overseas game companies, built sites in minutes and leased them to operators from offices in Vietnam and Cambodia. The companies, described as operating legally abroad, are not named.

• The Chungnam Provincial Police Agency's cyber crime unit said on Monday 19 October that it had caught 77 people and detained 21 over a network that allegedly built and leased 188 illegal gambling sites between March 2023 and July 2026, from bases in Vietnam, Cambodia and South Korea
• Police put the wagers placed through the sites at about KRW23 trillion, approximately $17.3 billion, a figure calculated from the network's game-credit records and bank accounts, and describe it as the largest in the country
• A "vendor" bought live casino video and game credits under contracts with well-known overseas game companies and sold them to a "solution" firm, which developed its own site-building software and charged KRW3 million (approximately $2,300) a month per site, according to the police account; no company was named
• All 188 sites have been taken offline, 408 web addresses blocked, KRW9.6 billion of alleged proceeds frozen before indictment and Interpol Red Notices sought for 12 suspects abroad
• The case follows a national crackdown in which police said many sites ran on the same platform, and comes after Cambodia made its online gambling shutdown permanent

Police Say They Took Out the Top of the Pyramid, Not the Sites

The Chungnam Provincial Police Agency's cyber crime investigation unit said on Monday that it had broken what it called the country's largest illegal gambling site supply organisation. Between March 2023 and July 2026 the group allegedly produced and leased 188 sites from offices in Vietnam, Cambodia and South Korea, opening gambling venues worth about KRW23 trillion (approximately $17.3 billion), according to the agency's announcement as reproduced by Korean outlets including Newsfreezone.

Of the 77 people caught, 25 belong to the supply organisation, 33 to downstream site operators and 19 are gamblers, SBS and Aju Business Daily reported; 18 of the supply group and three operators are in custody. Charges include opening a gambling venue, and 24 members of the solution firm, one still at large, also face charges of organising a criminal group under Article 114 of the Criminal Act. An earlier version of the figures, carried by several regional outlets on Monday morning, gave 72 caught and 19 detained.

Police describe five tiers: vendor, solution firm, site operators, recruiters working through adult PC rooms, and gamblers. The vendor contracted with overseas game suppliers for the right to stream casino video and to buy game credits, known as "al", and sold them on through its own distribution platform. The solution firm hired developers, including former staff of large IT companies, wrote a site-building program and leased the finished sites. SBS reported that the program could produce a site in 10 minutes.

Follow the Accounts, Then the Credits

The investigation began in November 2025 with the arrest of one downstream site's operators. Analysis of 795 bank accounts and overseas messenger records led police up the chain, and the KRW23 trillion comes from the vendor's game-credit administration pages and account data. Aju Business Daily notes that it measures stakes, not profit. SBS reported that police estimate the vendor's proceeds at about KRW120 billion and the solution firm's at about KRW30 billion, KRW150 billion (approximately $113 million) in all.

Police say the group recruited gang members to run sites, moved its offices often and used overseas servers, messengers and accounts in other people's names. The 408 web addresses were blocked at police request by the communications standards regulator. Pre-indictment freezing orders cover KRW9.6 billion (approximately $7.2 million); the earlier version said a court had approved KRW6 billion and was considering KRW3.6 billion. The National Tax Service has been notified, and 12 suspects abroad face Red Notice and repatriation requests. Asia Gaming Brief, which first reported the case in English, says they include two alleged leaders of the supply network.

Kim Tae-woo, head of the agency's cyber investigation unit, said cutting off the top of the supply chain had caused large numbers of sites to wither, according to SBS. Police did not identify the overseas game companies: the announcement calls them well known, and SBS describes them as legally operating abroad.

The Supply Layer Is Where Korean Enforcement Has Been Heading All Year

In June the Korean National Police Agency reported 2,319 arrests in a seven-month cyber gambling crackdown and said seized administration pages showed many sites running on the same platform, Herald Economy reported; it promised to pursue the companies that build and supply them. In July, Daegu police sent for prosecution a man repatriated from the United Arab Emirates who allegedly sold about KRW9 trillion (approximately $6.8 billion) of game credits to members of some 1,400 Korean sites, Segye Ilbo reported. The Chungnam case is the clearest result of that shift so far. Arresting operators produces new operators; removing a vendor and a builder takes away the inventory they all draw on. The test is whether it lasts: software that builds a site in 10 minutes can be rebuilt, and with 12 suspects abroad, not everyone who knows how is in custody.

"Legally Operating" Suppliers Are the Uncomfortable Detail

For the licensed industry, the most important line is the one without a name in it. If the game companies are licensed where they sit, their streams and credits still ended up on 188 sites serving a country where gambling outside a handful of licensed venues is a criminal offence, under the same Criminal Act Korean police have used against Polymarket traders. Nothing in the police account says the suppliers knew. But a chain in which a reseller buys feeds and credits and passes them down two further tiers is exactly the gap supplier due diligence is meant to close, and a question for the regulators that license live casino studios.

The Big Number Needs Context, and So Does Cambodia's Ban

KRW23 trillion over about 40 months is roughly KRW7 trillion a year on iGaming Times' arithmetic. The National Gambling Control Commission's sixth survey put Korea's whole illegal gambling market at KRW95.9 trillion (approximately $72 billion) in 2025, and the commission notes studies putting the illegal market at about three times the legal one. One network was a noticeable but minority share. Its bases matter too. Cambodia ordered casinos to stop online operations from October and is sending task forces into casinos in 16 provinces, while the US State Department has kept the country on Tier 3. The police account does not mention casinos: it describes offices that moved often, which a ban aimed at casino premises does not reach.

Chungnam police have shown that following the money from one site can reach the suppliers above it. The step that would change behaviour beyond Korea is identifying the licensed companies whose content fed the pyramid.
