South Korea lets exchanges freeze withdrawals on hack suspicion

South Korea's Financial Services Commission (FSC) issued a "no-action opinion letter" on November 12 allowing crypto exchanges to suspend deposits and withdrawals when a hack is merely suspected, without waiting for the attack to be confirmed. Existing rules allowed such a freeze only with clear evidence of a breach.

Details

Under the FSC document, an exchange may block transactions when there are signs of a hack or security incident, such as abnormal trading activity. The regulator says swift blocking measures are critical for limiting user damage in crypto attacks and cites the Binance hack as an example.

According to Cointelegraph, exchanges that cannot provide round-the-clock monitoring must limit operations to staffed hours and notify users. Regulators also want 24/7 incident response, more assets held in cold wallets, and stronger insurance and reserves. In October, 130 of 555 financial companies nationwide were found to have cybersecurity deficiencies.

The move follows recent incidents: Gopax halted trading and withdrawals after an email threatening a hack, and Prabang suspended services after suspicious hot-wallet withdrawals, with losses of about $70,000, Cointelegraph reports.

What this means for the market

For users of Korean exchanges, precautionary withdrawal freezes become a legitimate tool rather than a regulatory risk for the platform. The upside is faster protection of assets; the downside is more sudden freezes without a confirmed attack. Cold-wallet and insurance expectations add cost for smaller exchanges.
