Ribbon DOV vault was attacked causing a loss of $2.7 million, Aevo opens a six-month claim window

【Blockchain Rhythm】Aevo officially just released an important announcement: The old version of the Ribbon DOV vault on the platform was hacked on December 12th, resulting in a loss of approximately $2.7 million. The attack was caused by a vulnerability in the smart contract update, but the platform’s operations were not affected and continue to run stably.

The most severely affected are Ribbon vault users—these vaults lost about 32% of their total assets due to this attack. The official has immediately disabled all Ribbon vaults, and users are required to withdraw funds following the standard process. Note that withdrawal operations require completing a contract upgrade first, with the upgrade version to be launched next week. The specific date will be announced separately.

For affected users, Aevo has established a claims window of six months (December 12, 2024, to June 12, 2026). The compensation plan is as follows: after the six-month claims period ends, the DAO will liquidate all remaining assets and distribute them to users who have withdrawn, with the maximum compensation amount reaching 19% of the missing assets or the remaining available amount (whichever is lower). This means users have ample time to submit claim applications, and subsequent compensation distribution will be based on the actual available assets.
