South Korean Court Jails Three Men Over $17.6M Illegal Gambling Network Linked to North Korean Hackers
The Seoul Central District Court has sentenced three South Korean men to prison terms ranging from three to four years for collaborating with North Korean hackers to develop, maintain, and distribute illegal online gambling platforms. Handed down on Thursday, November 12, the rulings penalize a sprawling cyber-gambling operation that generated roughly 23.5 billion won ($17.6 million) between 2022 and 2024 by selling 16 illicit websites to domestic operators with more than 7 billion won ($5.2 million) funneled directly to Pyongyang-linked developers.
According to court findings, the operation’s alleged ringleader, identified by the surname Kim who had previously received a separate five-year prison sentence contacted China-based North Korean IT operatives to commission custom gambling software, including a mobile version of the popular slot game Sea Story (Bada Iyagi). Rather than a one-off build, the arrangement included ongoing technical support, server maintenance, and security management. Investigators linked the developers to General Bureau 313 and the Reconnaissance General Bureau, two key agencies behind North Korea’s state intelligence and cyber operations. Meanwhile, Kim’s two accomplices marketed the low-cost turnkey platforms to prospective illegal operators via Telegram and X, receiving three-year sentences each alongside a four-year term for the remaining defendant.
During the trial, Kim’s younger brother claimed he was unaware the software developers were North Korean nationals. Prosecutors dismantled that defense by presenting over 1,100 intercepted Telegram and chat messages containing distinct North Korean vocabulary most notably the term "sonjeonhwa" for mobile phone, rather than the South Korean equivalent. Consequently, the court convicted two of the defendants under South Korea’s National Security Act in addition to illegal gambling charges, while the third was convicted of operating illegal gambling facilities. In issuing the sentences, the bench emphasized both the severe national security risks of financing Pyongyang’s cyber apparatus and the broader social harm inflicted by illicit online gambling.
The case underscores persistent intelligence warnings regarding North Korea’s use of overseas IT workers to generate foreign currency for the regime. In 2024, South Korea’s National Intelligence Service (NIS) exposed a similar 15-person North Korean software cell operating out of Dandong, China posing as Chinese nationals and offering illicit gambling site builds for roughly $5,000 plus $3,000 in monthly maintenance fees in a scheme tied to Bureau 39, the regime’s slush-fund organization.
