Upbit Sanctions Loom as S.Korea Pushes for Tighter Crypto Oversight

The South Korean Financial Supervisory Service has begun sanctions proceedings against Upbit after a significant hack in November 2025. The incident saw hackers steal approximately $36 million worth of Solana-based assets from the exchange's hot wallet. The stolen funds, valued at about 44.5 billion won, were frozen within 54 minutes and transferred to cold wallets.

Upbit has promised to repay affected users, but the regulator is now reviewing whether the exchange met its security duties during the hack. Current laws in South Korea lack clear hacking penalties, which could lead to stronger crypto security rules being implemented as a result of this case.

The investigation may also shape future regulations aimed at improving exchange security and investor protection in the country's rapidly growing crypto market. Officials are considering new rules that would require stronger security standards and clearer customer compensation after cyberattacks.
