- The attacker executed a flash loan assault that manipulated the accounting mechanisms of the USDC vaults, enabling them to inflate assets artificially and redeem for profit.
- Following the incident, the protocol’s SUMR token lost more than 18% of its value.
Summer.fi, a decentralized finance protocol, has paused its Lazy Summer vaults after a security breach that resulted in roughly $6 million being stolen from its Ethereum-based yield platform, as reported by the project and various blockchain security experts.
Lazy Summer operates as an automated yield platform that seeks higher returns by directing deposits to lending markets like Aave and Morpho while managing rebalancing for users.
The exploit was initially identified by blockchain security firm Blockaid, with PeckShield and CertiK also noting abnormal activities. Summer.fi subsequently acknowledged it was probing the incident and indicated that protocol guardians had suspended the affected vaults to mitigate further losses.
Initial evaluations suggest that the perpetrator utilized a substantial flash loan, reportedly acquired via Morpho, to alter the accounting logic within the automated USDC vaults of Lazy Summer.
DeFi security analyst Bhari pointed out that the exploit exploited a vulnerability in the code, allowing the attacker to inflate the total assets and subsequently redeem them for profit. The stolen assets were reportedly converted to DAI on Curve before being moved to the attacker's wallet.
Before the exploit, the protocol had recorded $22 million in total value locked, according to data from DeFiLlama. Following the incident, the SUMR token experienced a decline of over 18% in value.
