Upbit Suffers $36M Solana Hack: Exchange Promises Full Reimbursement

Upbit, South Korea's leading cryptocurrency exchange, has announced a security incident resulting in the loss of approximately $36 million worth of cryptoassets on the Solana network. The exchange detected unauthorized withdrawals and swiftly suspended deposit and withdrawal services to contain the breach.

Quick Action and Reimbursement Promise

CEO Oh Kyung-seok of Dunamu, Upbit's parent company, assured users that the exchange will cover the entire loss using its own assets, ensuring no customer funds are impacted. This commitment aims to maintain user trust and confidence during this challenging time.

Details of the Hack

The breach occurred in the early hours of November 27th, with various Solana ecosystem assets, including SOL, USDC, and other smaller tokens, being transferred to an external wallet. Upbit has labeled the incident as “abnormal withdrawal activity” and has taken immediate steps to address the situation. These steps include:

• Freezing compromised funds where possible.
• Working with relevant projects and institutions to implement additional freezes.
• Shifting all assets to secure cold wallets.
• Launching an emergency security review.
• Cooperating with law enforcement.

Historical Context

This incident marks the second major security breach for Upbit. In 2019, the exchange lost a significant amount of ETH, which was later attributed to North Korean hackers.

Regulatory and Market Implications

The hack occurs amidst reports of a potential Nasdaq listing for Upbit following a multibillion-dollar stock swap merger with Naver. The security breach could potentially impact these plans, highlighting the ongoing risks associated with cryptocurrency exchanges.
