Beefy posted on X that it had operated 9 Sonne vaults on Optimism (7) and Base (2). The team responded within minutes of the Sonne attack by suspending all of these vaults, effectively withdrawing about two-thirds of the funds from Sonne, but some Optimism vaults were affected, meaning users of the affected products suffered partial losses.
The attack vector appears to be a problem specific to Compound forks and only affected Sonne's Optimism deployment. However, the situation remains fluid and all Sonne vaults remain suspended. Beefy will remain in contact with Sonne and will work with them to ensure any funds are returned to affected Beefy users if any funds are recovered or any other compensation is provided.
