<p><strong>Ribbon Finance's Ribbon DOV legacy vault</strong> experienced a breach on December 12 after a smart contract vulnerability was exploited by attackers. This incident resulted in the <strong>loss of approximately $2.7 million</strong> as attackers manipulated oTokens tied to the vault's settlement.</p>
