Financial regulators in South Korea announced a significant tightening of the "Virtual Asset Withdrawal Delay System" after discovering that weak exemption standards were exploited by voice phishing syndicates to launder criminal proceeds. The Financial Services Commission (FSC), the Financial Supervisory Service (FSS), and the Digital Asset Exchange Association (DAXA) confirmed that the new unified internal rules will take effect immediately to close loopholes used by scammers. The withdrawal delay system was initially launched in May 2025 to prevent instant movement of stolen funds by "mules." However, according to an FSC statement to the media, a recent review of regulatory requirements revealed a critical vulnerability whereby individual exchanges set their own criteria for bypassing these delays. Supporting this assessment, the statement cited data from June to September 2025, showing that 1,490 out of 2,526 fraudulent accounts were exempted from withdrawal delays. The total damage associated with these exemptions reached approximately $124 million (170.5 billion won), accounting for 75.5% of all losses from voice phishing using cryptocurrencies during this period. Criminals found it easy to bypass security measures by meeting simple criteria such as maintaining an account for a short period or conducting several small "fictitious transactions" to create a fake history. Under the new mandate, all exchanges must adhere to a unified and stricter standard. These mandatory factors require exchanges to conduct rigorous analysis of transaction frequency, overall account age, and total deposits and withdrawals. The FSC also defined conditions under which exemptions cannot be granted under any circumstances, regardless of trading history.#GateSquareAprilPostingChallenge
