BlockBeats News, December 14 — Aevo officials stated that due to a vulnerability in the smart contract update, the old version of the Ribbon DOV vault was attacked on December 12, resulting in a loss of approximately $2.7 million. The Aevo platform was not affected and will continue normal operation. All Ribbon vaults have been halted and will be immediately decommissioned, with approximately 32% of the total assets lost due to the attack. Users are advised to withdraw funds through the standard withdrawal process; the withdrawal requires an upgrade to the contract, which will be launched next week (announcement to follow). The claim window will be open for six months, from December 12 to June 12, 2026. After that, the DAO will liquidate all remaining assets and distribute them to previously withdrawn users, with compensation potentially covering up to 19% of the missing amount or the remaining available funds.
