Upbit loses about $36M as Solana hot wallet is drained; Lazarus suspected
On Nov 27, 2025, South Korea's largest exchange Upbit disclosed irregular withdrawals that drained roughly $36 million in Solana-network tokens from a hot wallet. Upbit froze the affected wallets, moved remaining funds to cold storage, said cold wallets were not breached and pledged to reimburse customers in full. South Korean authorities suspect North Korea's Lazarus Group, according to Yonhap, and CertiK said it tracked over 100 exploiter addresses on Solana. How the attackers got signing access has not been explained publicly. Customers did not need to act, but should treat any 'Upbit refund' message as phishing.
