Chainalysis attributes the Qubit/QBridge theft to North Korea-linked hackers and describes it as South Korea’s largest cryptocurrency theft of 2022, with roughly $80 million drained from the BNB-chain DeFi lending protocol. The attackers exploited QBridge logic to mint unbacked qXETH without depositing Ether, used it as collateral to borrow protocol assets, and bridged the stolen funds to Ethereum. The laundering flow matched DPRK-linked DeFi theft patterns observed in 2022: moving assets to a chain where freezing was harder, sending funds through Tornado Cash, swapping some proceeds on decentralized exchanges, and routing funds toward centralized exchange deposit addresses.
