Insider-aided wallet compromise.
Attacker wallets funded and staged ahead of the private key compromise exploit against Bithumb.
$31.0M drained from Bithumb on Ethereum via Private Key Compromise.
SlowMist flagged the anomalous transactions and published an initial alert.
Bithumb paused affected contracts or withdrawals and began tracing outbound flows.
Stolen assets followed through mixers, bridges, and exchange deposit addresses.
$14.0M of $31.0M recovered (45%); the remainder is still unaccounted for.
Remaining funds monitored across chains with exchange partners notified.
