One of the suspects arrested in connection with the murder of the half-brother of North Korea’s leader Kim Jong-un ran illegal online gambling operations on behalf of the regime.

On Wednesday, Korea JoongAng Daily reported that Ri Jong-choi, one of the suspects arrested in connection with last week’s murder in Malaysia of Kim Jong-nam, was operating illegal gambling and porn websites in that country while claiming to be working for an herbal supplement firm.

The 47-year-old Ri arrived in Malaysia last August, ostensibly to work at a small herbal supplement firm, but the company’s owner has since denied that Ri actually worked for him. Ri holds a software engineering degree from North Korea’s Kim Chaek University of Technology, a facility infamous for generating hackers.

North Korea’s isolated regime relies on a vast network of agents scattered across Asia whose job is to earn badly needed hard currency via a variety of illicit online activity, including operating gambling sites, selling gambling software and distributing malware to blackmail other websites into paying ransom. The regime is believed to earn over $860m per year from these online antics.
