- The Financial Supervisory Service is launching sanctions proceedings against Upbit operator Dunamu over a major 2025 hack and disclosure failures.
- The Financial Services Commission reports more than 40 unfair crypto trading investigations under the Virtual Asset User Protection Act and plans AI-based surveillance upgrades.
- Upcoming legislation and asset-law changes could harden penalties for hacking and manipulation, raising the compliance bar for Korean exchanges and traders.
Deep Dive
1. Upbit Hack Sanctions And Legal Gaps
The Financial Supervisory Service (FSS) has sent an inspection opinion letter to Dunamu, operator of Upbit, formally starting a sanctions procedure over a November 2025 wallet breach that drained about $3036 million in Solana-based assets. The exchange froze roughly 2.3 billion won in funds, pledged to fully reimburse customers, and overhauled its wallet architecture, including launching an Onchain AI Tracer System to track stolen funds, as described in a detailed FSS sanctions report.
Regulators are also scrutinizing Upbits delayed public disclosure, which came only after a merger-related event with Naver Financial concluded. The case highlights a legal gap: the Virtual Asset User Protection Act covers custody and unfair trading but does not explicitly set penalties for hacks or IT failures, leaving the scope of possible sanctions uncertain for now.
Korean exchanges face growing pressure to demonstrate robust security and rapid incident disclosure, even before dedicated hacking-penalty rules arrive.
2. Crackdown On Manipulation And Unfair Trading
On the second anniversary of the Virtual Asset User Protection Act, FSC Chair Lee Eog-won disclosed that authorities have investigated over 40 cases of unfair crypto trading, including market manipulation, insider trading, and fraudulent schemes, identifying 25 suspects and referring around 30 cases to law enforcement. Average unlawful gains were about 1.4 billion won (roughly $940,000), according to his public update.
The Act requires virtual asset service providers to segregate client assets from corporate funds and hold cash deposits at banks, while expanding the FSCs powers to inspect platforms and target practices like wash trading and pump-and-dumps. Authorities now plan to strengthen surveillance further with AI-based monitoring capable of real-time data analysis and automatic detection of suspicious accounts and trading intervals.
Confidence: high. These figures and plans come directly from senior regulators and recent policy communications.
3. Next Rules And Risks For Korean Crypto
South Korea is moving to embed crypto more deeply into its legal framework by proposing to include virtual assets in the National Asset Basic Law, formally recognizing them as an asset class within state statute, as outlined in a policy explainer. In parallel, the second phase of the Digital Asset Basic Act is expected to add explicit sanctions and compensation rules for hacking and system failures, closing the gaps exposed by the Upbit case.
Legislative debates around stablecoin reserves and exchange ownership caps have slowed passage of a fully unified digital asset law, but the enforcement trend is clear: more structured oversight, tougher penalties, and technology-driven surveillance. Risk note: stricter policing of manipulation and security failures could push some activity to offshore or lightly regulated venues, which may carry higher counterparty and custody risks.
Conclusion
South Korea is evolving from ad hoc crypto enforcement to a more systemic, law-backed and technology-driven regime that targets both market misconduct and operational security. For crypto users and projects tied to Korean markets, the direction is toward tighter rules, higher compliance expectations, and faster detection of unfair trading, with upcoming legislation likely to harden consequences for hacks and manipulation. Monitoring how these rules are finalized and applied will be key to understanding future liquidity and risk in Korean wondenominated crypto trading.
