Balancer DAO Issues Onchain Warning to ETH Exploit Culprits, Offers Bounty

The exploit, which Balancer reported to its users on Monday, resulted in more than $100 million worth of staked Ether (ETH) — including StakeWise Staked ETH (OSETH), Wrapped Ether (WETH) and Lido wstETH (wSTETH) — being moved to a newly created wallet. The hack drew attention to the audits of the exchanges smart contracts after reports showed four security companies had reviewed them.

How did the exploit happen？

According to a post-mortem report on the exploit from Wednesday, the platform said hackers used a combination of BatchSwaps and the upscale rounding function that affects EXACT_OUT swaps to exploit its v2 Stable Pools and Composable Stable v5 pools.

One of the auditors was contacted for further insights, but no response was available at the time of this report.

Although the onchain message did not specify the amount of the bounty, Balancers team initially said that it would offer up to 20% of the stolen funds, which is more than $20 million. No one appeared to have accepted the onchain offer at the time of publication.
