Upbit, the dominant cryptocurrency exchange in South Korea, has experienced a significant security incident resulting in the loss of approximately 54 billion won, equivalent to $36 million. The exchange has moved swiftly to reassure its users, confirming that all their assets are secure and pledging to cover the full financial impact from its own funds.
Details of the Solana Ecosystem Breach
The security breach occurred in the early morning hours, characterized by unusual transactions involving digital assets from the Solana ecosystem. Cryptocurrencies including SOL, USDC, BONK, and others were reportedly diverted to an unidentified wallet. Oh Kyung-seok, the CEO of Upbit, emphasized that the protection of user assets is the highest priority and committed to complete reimbursement using Upbit's own financial resources. The balances in user accounts remain unaffected by this incident.
Following the discovery of the breach, Upbit immediately halted all trading activities. The exchange implemented system-wide lockdowns and transferred affected funds to cold storage for enhanced security. An internal investigation has confirmed that 12 billion won worth of LAYER tokens have been successfully frozen, and efforts are ongoing to trace the remaining stolen assets. Upbit is actively collaborating with relevant blockchain projects and law enforcement agencies on this matter.
Historical Context of Upbit Security Incidents
This recent breach occurs close to the anniversary of Upbit's major hack in 2019, which saw the theft of 342,000 ETH. That incident was later attributed to a state-sponsored group from North Korea. While there is no official connection between the two events, the timing has drawn attention. The Ethereum stolen in the 2019 hack is now valued at over $1 billion.
The security lapse comes at a critical juncture for Upbit, as tech giant Naver is reportedly considering acquiring Upbit's parent company, Dunamu, in a significant stock transaction. This incident poses a challenge to Upbit's established reputation. However, the decision to absorb user losses is viewed as a strategic move to maintain user trust. Upbit plans to gradually resume transactions once comprehensive security assessments are completed.
Key Takeaways from the Incident
- •The total financial loss incurred is 54 billion won, or $36 million.
- •User assets have not been compromised and remain secure.
- •Upbit has committed to providing full compensation to affected users using its own funds.
- •Emergency security measures included freezing trading systems and moving assets to cold storage.

Upbit issued a statement affirming their dedication to client financial safety: "We remain committed to our clients’ financial safety and will utilize all available resources to address and rectify this situation." This incident serves as a potent reminder of the persistent vulnerabilities inherent in cryptocurrency exchanges, even for leading platforms. Upbit's decisive actions underscore the critical importance of trust and robust security in the contemporary financial landscape.
