According to Foresight News, CertiK released a report on the Dough Finance vulnerability incident. Dough Finance was exploited in multiple flash loan transactions on July 12, and the hacker made a profit of about $2.1 million, of which about 76 ETH (about $260,000) has been returned by the white hat hacker. The attacker exploited the arbitrary call vulnerability in the Dough ConnectorDeleverageParaswap contract to transfer WETH directly from the vulnerable contract.
