After discovering abnormal withdrawals from the Solana-related wallet, the team immediately conducted a comprehensive investigation of the relevant network and wallet system, and found that some on-chain transactions on the platform exposed security vulnerabilities that could infer private keys, which have now been urgently repaired. According to official disclosures, the current locked overall loss is approximately 44.5 billion Korean won, of which approximately 38.6 billion Korean won is user asset loss, and approximately 2.3 billion Korean won of related tokens have been successfully frozen; another approximately 5.9 billion Korean won belongs to the platform's own assets.

Upbit has fully covered user losses with its own funds and has suspended all digital asset deposits and withdrawals to track outflows and continue to take freezing measures. Upbit stated that it is comprehensively reconstructing the wallet system and will reopen deposits and withdrawals after stability verification. At the same time, the company has launched a company-wide security review mechanism, which will use this incident as an opportunity to further strengthen security infrastructure and maintain transparent disclosure of publicly available content in the future. Kyung-Seok Woo emphasized that "there is no absolute security," and Upbit will comprehensively improve its protection system to avoid similar incidents from happening again.
