South Korea's Financial Intelligence Unit (FIU) ordered the blocking of 27 cryptocurrency exchange websites, including KuCoin, MEXC, BingX, and Phemex, on October 13. This action extends previous restrictions that had already blocked mobile applications for unregistered foreign exchanges via Apple App Store and Google Play. The Korea Media and Communications Standards Commission approved these website blocks following regulatory reviews conducted on October 6 and 7. Other affected platforms include Poloniex, BTCC, BitMart, XT.com, Bitrue, CoinW, and DigiFinex.

The enforcement targets virtual asset service providers operating without local registration under the Act on Reporting and Using Specified Financial Transaction Information. Unregistered operators face criminal penalties, including up to five years of imprisonment or fines of 50 million won. The FIU has referred 44 unregistered operators to investigative authorities. While the restrictions remove browser-based access channels, they do not imply that customer assets have been seized or that the exchanges have ceased global operations. Regulators plan to coordinate with the Digital Asset eXchange Alliance (DAXA) to assist existing customers in withdrawing remaining assets.
