<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>
<p><strong>Immediate actions taken by Ribbon Finance include halting all operations</strong> of their vaults after identifying the breach. This halt preserves existing fund integrity, while users are advised to withdraw assets.</p>
<blockquote>
 "The attacker established substantial oToken against Ribbon's Margin, utilizing these falsified expiry prices within its settlement pipeline to transfer hundreds of ETH and stETH of US, and WBTC addresses associated with the theft via redeem and redeemTo transactions." - Liyi Zhou, Web3 Security Expert
