Arcus DEX Exploit: $2.23 Million Loss
Arcus DEX suffered a $2.23 million loss due to an accounting bug in its subaccount transfer system. An attacker manipulated account balances to make it appear as though more funds were available for withdrawal than actually existed. Arcus Labs covered the loss using company funds, and the platform stopped another $3 million in attempted withdrawals. The attack involved a newly created account and was prevented from becoming worse due to the platform's withdrawal security system.
