Attackers Steal Over $120M From Balancer in One of 2025’s Largest DeFi Hacks

Decentralized exchange and liquidity protocol Balancer has suffered a major security breach, with attackers stealing over $120 million in digital assets.

Blockchain analytics firms Lookonchain and Nansen that the exploit is still active, with stolen funds moving across multiple linked wallets.

On-chain data shows that the attackers took around:

The stolen tokens were transferred to a new wallet flagged as suspicious by analysts. This ranks among the largest DeFi hacks of 2025, raising renewed concerns about the security of decentralized finance protocols.

Despite increased auditing and regulation efforts, this incident shows that even established DeFi platforms remain vulnerable to smart contract flaws and poor configurations.

On-chain security expert Clyde on X that the breach shows the urgent need for “real-time audit visibility” in DeFi pools. He recommended tools such as DeBank and DefiLlama to track suspicious wallet activity.

The Balancer hack underscores the ongoing security challenges in decentralized finance. Many DeFi protocols remain at risk from coding bugs, flash loan exploits, and setup errors.

Balancer was previously hit by a smaller exploit in 2023, which cost the platform about $238,000. The scale of this new breach marks a major escalation in both impact and sophistication.

The Balancer exploit came as the broader crypto market experienced mixed performance. Bitcoin is trading at a loss of 3.2% in the past day at $107,111, while Ethereum slipped below $3,700 after a 4.5% downtrend.

The Balancer breach adds pressure on decentralized platforms to tighten security measures and reassess governance processes. An analyst expects emergency votes, temporary protocol pauses, and potential recovery attempts if the attackers begin moving stolen funds across chains.
