- Balancer Protocol has suffered an exploit.
- This follows a critical vulnerability warning on August 22.
- The hacker is still active, transferring funds.
DeFi protocol and Ethereum automated market maker (AMM) Balancer was exploited, leading to a loss of over $900,000 worth of crypto. The protocol confirmed the exploit via Twitter on August 27 and encouraged users to withdraw their funds from the affected liquidity pools.
The development comes a few days after Balancer reported a critical vulnerability in its V2 pools.
The Hacker Used an Ethereum Address
Cyvers founder and CTO Meir Dolev was among the first blockchain security experts to comment on the matter, noting that the hacker used an Ethereum address to transfer the stolen funds in DAI stablecoin.
While primary sources indicate that the hacker conducted two transactions totaling $893,978 in DAI, the associated wallet address had received another 85,080 DAI at the time of press. Cumulatively, the address now holds $978,947 worth of DAI.

“Mitigation procedures have drastically reduced risks but are unable to pause affected pools. To prevent further exploits, users must withdraw from affected LPs,” read Balancer’s tweet.
Alert on Critical Vulnerability
The Balancer Protocol team issued a vulnerability warning on August 22, noting that its boosted liquidity pools were susceptible to an attack.

Over $5 million of assets were exposed to risks during the vulnerability discovery, representing about 1.4% of the protocol’s total assets deployed on Ethereum, Optimism, Polygon, Avalanche, Gnosis, Arbitrum, zkEVM, and Fantom.
On August 25, the protocol released an update stating that 99.7% of the liquidity deemed vulnerable was safe, with only $565,199 of the total value locked remaining at risk.
Despite the previous mitigation measures aimed at lowering the vulnerability risks, the hacker still managed to steal more than what was deemed vulnerable, with recent wallet activity showing that the amount is almost a million.
