South Korean gambling ring that wagered $230M used hearing-impaired people as payment mules

Police in Busan say a gambling network routed $230 million (KRW 320 billion) through recruited bank accounts, including accounts belonging to people with hearing impairments. For PSPs and acquiring teams, the detail that matters is the mechanics: payment flows were split across 90 accounts to mask the real operators and keep the activity below the radar.

1. Investigators first opened a case around a low-profile illegal gambling website, but it quickly became clear they were looking at a broader operation. Police say the group used “mules” to process payments worth $3.8 million over a few months before the full structure came into view.
2. The Busan Metropolitan Police Agency identified that the bank accounts receiving money from the site belonged to people with hearing impairments. That gave officers the first concrete sign that the scheme was not just illegal gambling, but also a recruitment-and-account-sharing operation built around vulnerable account holders.
3. Police say a 40-something interpreter for people with hearing impairments played a central role. Victims were told that processing gambling payments through their accounts would improve their credit score, and the interpreter was allegedly paid about $1,100 per account to keep recruiting participants and preserve the cover story.
4. The group secured 90 bank accounts in total. The accounts were used not only for the website that triggered the investigation, but also for other sites and for “hedge” betting, or “two-way gambling” as South Korean outlets described it: betting on opposite outcomes of the same event to lock in a margin, while also taking advantage of promotional offers.
5. Following the initial investigation, police arrested 172 people linked to the scam, including gamblers and people behind the gambling websites. Six suspects, including the interpreter, were referred to prosecutors and are in custody.

For high-risk PSPs, this is a familiar compliance problem with a local twist: recruited accounts, fragmented inflows, and third-party payment processing used to obscure source and purpose of funds. When the transaction trail runs through multiple personal accounts instead of a merchant structure, the betting operator gets time; the bank or PSP gets the mess.
