Balancer Recovers $19.3M, Hours After the Multi-Million Dollar DeFi Hack 

The Balancer DeFi protocol recovered $19.3 million hours after what’s likely to be the biggest DeFi hack in 2025. The hack that happened on Monday,  November 3, has reportedly resulted in a loss of $128 million. The prompt response from Balancer led to the current recovery; nonetheless, the attack had exposed the vulnerabilities in the system. 

According to the post on X  from StakeWise, reposted by Balancer, around 5,041 osETH worth $19M  and 13,495 osGNO valued at around $1.7 million are recovered from the Balancer exploiter. The post further noted that the recovered amount represents around 73.53% of osETH. The rest of them were converted to ETH by the hacker. Following the recovery, the crypto analyst EmberCN said that the assets stolen by the hacker from Balancer had dropped from $117 million to $98 million.

Details of the Balancer’s $128M DeFi Breach

Balancer V2 Composable Stable Pools are affected by the breach on Monday. The hacker exploited a vulnerability in the smart contract authorization to orchestrate the breach. The in-depth analysis shows that the hacker has exploited the function that manages user balances. The exploiter moved the funds by bypassing the ownership checks. The attacker manipulated the Balancer’s system to transfer funds from liquidity pools holding Etherium-based assets to their own wallet by deploying malicious smart contracts and fake token interactions. The major tokens transferred are WETH (Wrapped Ethereum), osETH (Staked Ethereum issued by Origin Protocol), and wstETH (Wrapped Staked Ethereum from Lido Finance).

The Balancer confirmed the attack on V2 Composable Stable Pools within hours and assured the stakeholders that their team was working with leading security researchers to understand the issue and would share additional findings and a full post-mortem as soon as possible.

Following the attack, the platform’s total value locked (TVL) reduced from $442 million $214.52 million within a day. An inactive whale had reportedly moved 6.5 million from the Balancer.

The Bottom Line: A Cautionary Tale

According to Statista, the DeFi sector in the U.S  will experience an annual growth rate of 3.59% (CAGR 2025-2026).  And is projected to reach a total of US$2.6 billion by the year 2026. The estimates show the growing relevance of the sector, but cyber attacks remain a huge threat to the niche endeavours and participants.

Even though the present attack shows the vulnerability of the platforms, the prompt response from Balance is reassuring. Yet the event shows that the networks should put more focus on the security aspects and avoid any blind spots for the exploiters to attack. The traders, on the other hand, need to be aware of the risks associated with such unpredictable events and be prepared.
