Aevo recently officially confirmed a serious attack targeting older versions of DOV Ribbon vaults, causing approximately $2.7 million in losses, and pledged to compensate active users. This information quickly attracted significant attention from the DeFi community, especially given the ongoing hot topic of asset security on Derivative protocols and options strategies.
According to Aevo's announcement, the incident only affected "legacy" Ribbon DOV vaults, meaning those deployed before Ribbon was more deeply integrated into the Aevo ecosystem. Immediately after confirming the attack, Aevo decided to close all remaining Ribbon vaults to prevent the risk from spreading, and recommended that users with unwithdrawn deposits withdraw their assets as soon as possible.
However, due to the asset structure and the extent of the damage, Aevo stated that, for the time being, users can only withdraw a maximum of approximately 19% of the value of their deposited funds. This rate will be applied until June 12th of next year. Aevo explained that the initial allocation was set quite low because the majority of accounts in the system are "dormant" accounts, meaning they are almost inactive and unlikely to ever make withdrawals. Therefore, the protocol prioritizes protecting the interests of users who are still actively using the system.
