SEOUL, November 27 (AJP) - Upbit, South Korea’s largest cryptocurrency exchange, said Thursday that digital assets worth about $31 million were stolen in an early-morning security breach, marking the platform’s most serious incident since its major hack six years ago.

Operator Dunamu said the breach was detected around 4:40 a.m., when assets on the Solana network were transferred to an unauthorized wallet. The stolen holdings include Solana (SOL) and 23 other tokens such as DoubleZero (2Z), Access Protocol (ACS), Bonk (BONK) and Doodles (DOOD).

“Upon detecting the anomaly, we immediately halted all Solana-related transactions and initiated a comprehensive security review,” Dunamu said in a statement. “The loss has been fully covered by Upbit’s own assets.”

The company added that remaining assets had been moved to offline cold wallets to prevent further unauthorized transfers and that it is preparing to cooperate with law enforcement.

The incident is the first major theft involving Upbit since November 2019, when 342,000 Ethereum — then valued at roughly $500 million — were moved from the exchange’s hot wallet to an external address.
