TechFlow news, on November 28, Oh Kyung-seok, CEO of Dunamu—the parent company of Upbit—issued an apology statement regarding the platform's recent cyberattack incident, acknowledging that the breach resulted from internal security management lapses and pledging zero losses for users. Upbit stated that the incident occurred on the morning of the 27th when abnormal withdrawals were detected from its Solana-linked wallet. The team immediately conducted a comprehensive review of its network and wallet systems, subsequently fixing a critical vulnerability that could potentially allow private key inference through on-chain transaction analysis. To date, Upbit has determined that approximately 44.5 billion KRW in digital assets were affected, including 38.6 billion KRW in user assets, of which 2.3 billion KRW have already been frozen; the company itself sustained losses of about 5.9 billion KRW. Upbit emphasized that all user losses have been fully compensated using the platform’s own funds.
