Dough Finance Hack

On July 12, 2024, Dough Finance, a DeFi protocol, lost $1.8 million in digital assets due to a flash loan attack

On July 12, 2024, Dough Finance, a DeFi protocol, lost $1.8 million in digital assets due to a flash loan attack. Web3 security firm Cyvers flagged suspicious transactions and confirmed that Aave's pools were safe, though Dough Finance was heavily impacted. The attacker used the ZK protocol Railgun to fund the attack and swapped stolen USD Coin for 608 ETH, worth about $1.8 million.

Web3 security provider Olympix identified the cause of the exploit as unvalidated call data within the “ConnectorDeleverageParaswap” contract, allowing the attacker to manipulate data during flash loan calls. After the exploit funds were mixed with a Tornado mixer.
