After discovering abnormal withdrawals from the Solana-linked wallet on the morning of the 27th, 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 a security vulnerability that allowed for the deduction of private keys, which has now been urgently fixed.</p><p> According to official disclosures, the total locked-up losses amount to approximately 44.5 billion Korean won, of which user asset losses are approximately 38.6 billion Korean won, and approximately 2.3 billion Korean won worth of related tokens have been successfully frozen; another approximately 5.9 billion Korean won belongs to the platform&#39;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.</p><p> Upbit stated that it is undergoing a complete overhaul of its wallet system and will reopen deposits and withdrawals after stability verification. Simultaneously, the company has initiated a company-wide security review mechanism, using this incident as an opportunity to further strengthen its security infrastructure and maintain transparent disclosure of all publicly available information.</p><p> Wu Jingxi emphasized that &quot;there is no absolute safety,&quot; and Upbit will comprehensively upgrade its protection system to prevent similar incidents from happening again.</p>
