Upbit Confirms $36M Solana Network Breach, Pledges Full Customer Reimbursement

South Korean crypto exchange Upbit disclosed a security incident on November 27 involving approximately $36m in Solana-based assets transferred to an unknown wallet. The platform immediately suspended deposit and withdrawal services and committed to covering all losses from its own reserves without impacting customer balances. The breach occurred nearly six years after Upbit lost 342,000 ETH to North Korean actors in a November 2019 attack.
