Summer Finance Suffers $6M Loss From $65.4M Flash Loan Attack on July 6

GateNews
Security Incidents
According to Certik and Bitcoin.com, on July 6, 2026, Summer Finance's Lazy Summer Protocol suffered a $6 million loss from a $65.4 million flash loan attack. The attacker exploited a vulnerability in the Fleet Commander contract's asset accounting logic to artificially distort token value calculations. After depositing approximately $64.8 million into the manipulated system, the actor redeemed $70.9 million in assets and converted the $6 million profit into DAI stablecoins before moving funds to an attacker-controlled wallet, according to Cyvers. Following the breach confirmation, Summer Finance paused all Lazy Summer Protocol vaults while the development team investigates the vulnerability and prepares a comprehensive patch.
