Upbit CEO issues public apology: confirmed losses of 44.5 billion won, and has fully compensated users for their losses.

Upbit's parent company, Dunamu, CEO Kyung-seok Oh, issued a public apology today regarding the abnormal withdrawal incident on the Solana blockchain. Oh acknowledged that the security incident stemmed from internal security management deficiencies and emphasized that Upbit bears "undeniable responsibility." Oh stated that Upbit has reported the incident to relevant authorities and launched a full investigation in accordance with regulations. After discovering abnormal withdrawals from Solana-linked wallets on the morning of the 27th, the team immediately conducted a comprehensive investigation of the relevant network and wallet systems, discovering a security vulnerability in some on-chain transactions that allowed for the deduction of private keys. This vulnerability has now been urgently fixed. According to official disclosures, the total locked losses are approximately 44.5 billion Korean won, including approximately 38.6 billion won in user assets, of which approximately 2.3 billion won in related tokens have been successfully frozen; another approximately 5.9 billion won belongs to the platform's own assets. Upbit has fully covered user losses with its own funds and suspended all digital asset deposits and withdrawals to track outflowing assets and continue to take freezing measures. Upbit stated that it is currently conducting a complete reconstruction of the wallet system and will reopen deposits and withdrawals after stability verification. Meanwhile, the company has initiated a company-wide security review mechanism and will use this incident as an opportunity to further strengthen its security infrastructure, maintaining transparent disclosure of any publicly available information. Wu Jingxi emphasized that "there is no absolute security," and Upbit will comprehensively upgrade its protection system to prevent similar incidents from happening again.
